FOREWORD

M

ore and more people realise the importance of good oral health and how negative the impact of oral diseases can be on daily performance, social participation and general well being. Oral diseases are to a very large extent preventable, yet when they occur they can be among the most expensive to treat or cure. Despite the central role of the mouth as gateway to, and mirror of, the body, general knowledge about prevention of oral disease is limited. Health planners and politicians are often unaware of the magnitude and impact of oral diseases and believe dental treatment and preventive services are an optional luxury. Others think that oral care is just too costly for their health care system, and often no budgets are allocated to this sector. Yet simple, effective and evidence-based interventions exist that can help, in rich and poor countries alike, to reduce the burden of oral diseases significantly.

“Oral health is a neglected area of international health” – these words of the Director-General of the World Health Organization, Dr. Margaret Chan, expressed during the landmark 120th session of the WHO’s Executive Board in 2007, were a wake-up call for the international health community. They were also tremendous encouragement for us to continue the long-standing advocacy work of the FDI World Dental Federation.

Dental caries is the most common chronic non-communicable disease in the world, but few people, even in public health, know about this fact. This Oral Health Atlas is intended to draw attention, in a graphic manner, to the huge burden of oral disease around the globe, highlighting the key risk factors, workforce issues, stakeholders and solutions. It is hoped that it will be used as a tool to both demonstrate the problems and motivate health care providers, governments and the public to take action.

Oral health is subject to a number of key risk factors. Fortunately, avoidance of risk factors such as high sugar consumption, poor nutrition, poor basic hygiene and tobacco use will also prevent many other serious health problems. Good oral health is not something that we should take for granted. The recognition of oral health as a basic human right commits all of us, particularly the dental profession, to do everything possible to improve access to quality care and preventive programmes – for every citizen of the world.

This Atlas provides a snapshot of the status and challenges of oral health globally. Its maps clearly highlight the lack of current data in many areas important to oral health. I see it as the first edition of an important publication that will be updated periodically to capture and communicate the ever-changing picture of global oral health. I encourage FDI member associations and other organisations to translate the Oral Health Atlas into other languages to facilitate the dissemination of information.

The FDI World Dental Federation, with its vision of “leading the world to optimal oral health”, is proud to present this Atlas to the global audience. Please study and use it to help make the dream of “(Oral) Health for All” become a reality.

PREFACE

T

he Oral Health Atlas is intended for readers interested in global health issues, and serves as an invaluable resource for health professionals and policy makers, and for those interested in how better to look after their own oral health. The Atlas demonstrates that oral health has all the ingredients of a fascinating public health story: it is both personal and political, encompassing total health, political will, economics, big business (sugar, tobacco and personal care), allocation of resources, poverty, children and human development, and it will be crucially important in the future.

There are several surprises for most general readers and even, we suspect, for many health professionals: • The first is that oral health problems and rudimentary treatments have been identified and described for many thousands of years.

• Secondly, oral health is not limited to teeth – there are many intriguing parts of the mouth, with surprising functions, which also need to be cared for.

• Oral health does not just involve the mouth but is intertwined with the health of the whole body. Thus, modern oral health care is far removed from the traditional “drill, fill and bill” concept of dentistry, but rather involves caring for the health of the complete body.

• Perhaps more expected, but utterly regrettable, the Atlas maps the huge gap in oral health between rich and poor countries, high- and low-income populations. The little boy on the cover exemplifies the high-risk child: from a low- or middle-income country, probably without access to adequate dental care, who already has serious tooth decay – a path towards life-long oral health problems.

The Oral Health Atlas maps the history, documents the current situation and challenges, as well as predicts the future of oral health. There is a marketing maxim “If you can’t measure it, you can’t manage it” and the Atlas emphasises the urgent need for better data on oral health. We encourage you to read our comments on the data sources where the problems and shortcomings of current global oral health data are highlighted.

The Atlas also looks at solutions and reflects the importance of multiple approaches to improving oral health, requiring action by the World Health Organization, governmental and non-governmental organisations (NGOs), the private sector and individuals. Integration and collaboration are the key words here; oral health initiatives require that efforts be made both to alter personal behaviour and inform population policy. We hope that a future edition of the Atlas will be able to map the broad landscape of other stakeholders, such as the dental industry, dental NGOs and others.

In the last few decades we have seen developments and improvements which have had a global impact, ranging from the introduction of fluoride toothpaste in 1955 to the reduction of one of the major risk factors – tobacco – by the 2005 WHO Framework Convention on Tobacco Control. The good news is that nearly all oral diseases are preventable and most are also treatable. Unlike our colleagues in other fields of health, we are lucky enough to have both the knowledge and the tools to significantly improve oral health worldwide, drastically improving both the quality of life and economic productivity of nations.

The Atlas is thus a challenge, an opportunity and a “call to action” to be bold and improve oral health now, so that within our lifetime millions of people will be able to benefit from better health and human development.

O

ral health is an important international public health issue; oral diseases have a significant impact on individuals, communities, health systems, economies and society at large.

Oral health refers to the entire mouth, not just the teeth. It includes the gums, the hard and soft palate, the linings of the mouth and throat, the tongue, lips, salivary glands, chewing muscles, and the upper and lower jaws.

The World Health Organization defines oral health as “a state of complete physical, mental and social wellbeing, not merely the absence of tooth decay, oral and throat cancers, gum disease, chronic pain, oral tissue

Oral health is an essential and integral component of overall health. Oral diseases impact on general health and systemic diseases show symptoms in the oral structures. An unhealthy mouth and teeth may limit people’s ability to take in food, thereby affecting their capacity to study or work. It may also affect their social interactions.

Tooth decay (dental caries) and gum diseases (periodontal diseases) affect virtually every human being during their lifetime, although both diseases are almost entirely preventable.

he development of the human dentition is a complex process, with a primary set of 20 teeth and a permanent set of 32 teeth. Occasionally, there are extra (supernumerary) teeth. Primary teeth (baby teeth, milk teeth or deciduous teeth) start to form between the sixth and eighth week in the womb, and permanent (secondary) teeth begin to form in the twentieth week in the womb.

Babies get their first teeth at around six to eight months of age, usually starting with the lower two front teeth. The remaining baby teeth erupt at regular intervals and usually all 20 teeth have erupted by the age of two-and-a-half. Like adult teeth, primary teeth are important for both eating and appearance, but they also act as a stimulus for the jaws and face

Eight muscles are needed for chewing – their maximum force is 200 kg/cm2 (the force of a lion’s bite is about 350 kg/cm2).

Normal saliva production can vary from between 0.75–1.5 litres per day.

to grow and maintain spaces for the permanent teeth to erupt from underneath. Early loss of baby teeth as a result of accidents or tooth decay often leads to overcrowding of the permanent teeth.

The permanent teeth start to erupt around the age of six to eight and again, the front teeth (incisors) on the lower jaw are usually the first to appear.

While the outer coating of the tooth (enamel) is the hardest tissue of the human body, teeth have a soft-tissue interior (pulp) with nerves and blood vessels. Throughout life, tooth wear causes loss of enamel or underlying dentin. In the absence of gum diseases or other reasons for tooth loss it is possible to retain a functioning full dentition for a lifetime.

SOME IMPACTS OF ORAL CONDITIONS ON GENERAL HEALTH HIV/AIDS often manifests in the mouth.

Diabetes can result in delayed wound healing and the worsening of gum disease.

Low blood sugar level can be detected by a characteristic odour.

Leukaemia may result in oral ulcers.

Syphilis during pregnancy can result in characteristic tooth and palate malformation in the child.

Tetracycline antibiotic use by pregnant mothers or children can result in an enamel malformation and staining of the children’s teeth.

Stress and psychological disorders can lead to grinding, clenching and TMJ joint problems.

Measles is usually detected by characteristic spots on the inner cheeks.

Down Syndrome often includes an enlarged tongue.

Tuberculosis may show as a characteristic ulcer of the tongue surface or other oral tissues.

Drug abuse is often associated with severe caries and tooth loss.

Xerostomia (dry mouth due to lack of saliva) results in rapid dental decay.

Bulimia often causes characteristic tooth erosions (from gastric acid).

Tetanus infection may result in lockjaw.

Various genetic syndromes cause malformation of teeth and jaws.

he mouth is a gateway to the body and can be used as an early warning system for health practitioners. Signs in the mouth can indicate trouble in other parts of the body. For example, mouth lesions and other oral conditions may be the first sign of HIV infection and can be used as indicators to follow its progression to AIDS. An oral examination can also reveal other diseases, general health status and habits such as tobacco and other drug use.

Oral diseases share common determinants with many other chronic diseases, such as diabetes and heart disease. The mouth should be seen as an interrelated part of the body. Patterns of oral disease mirror those of many other chronic diseases. Inequalities in both general and oral health

ORAL HEALTH AND GENERAL HEALTH 3 Dental treatment is required before heart surgery to avoid complication from dental infections.

SOME IMPACTS OF SYSTEMIC DISEASE ON ORAL HEALTH

Edentulousness (loss of teeth) within the elderly population results in impaired ability to chew and can lead to malnutrition.

Dental infections have been associated with higher increased risk for pneumonia.

The mouth may be a reservoir for bacteria associated with stomach ulcers.

Saliva and oral swabs are used to detect compounds, genes, diseases and conditions, as well as to identify individuals through their DNA.

Gum disease can complicate diabetes.

Oral bacteria are associated with infective arthritis.

The mouth can reflect the state of general health. Conversely, oral diseases can have an impact on general health.

Gum disease can be the starting point for noma.

Oral bacteria are associated with infective endocarditis (inflammation of the heart's inner lining).

Gum disease has been associated with higher risk of cardiovascular disease.

Gum disease has been associated with higher risk of pre-term babies.

Gum disease has been associated with higher risk of low-birthweight babies.

are also very similar. These similarities highlight the close association between oral and general health.

Oral and general health are linked and jointly influenced by psychosocial factors such as stress, behaviours such as diet and smoking, and broader socio-environmental factors. The evidence to date highlights the need for future oral health preventive programmes to be more integrated with general health-promotion activities.

ental decay (caries) is a major global public health problem. Caries is the most common childhood disease worldwide and the most common non-communicable disease on the planet. Caries is a multi-factorial disease for which at least three main factors must come together: dietary sugars (including carbohydrates), oral bacteria and time.

Put simply, bacteria metabolise sugars and produce acids, which over time break down tooth enamel. The consequences of this process, if left untreated, are the destruction of the tooth’s hard tissues, pain, abscess and possible tooth loss.

Caries can be diagnosed by sight, by using a probe, via x-ray (radiograph) or other advanced technology. Caries usually starts, often hidden from view,

TOOTH DECAY 4 Dental decay (caries) is the most common chronic disease on the planet, yet it is preventable.

EARLY CHILDHOOD CARIES As soon as a child’s teeth appear, at around 6 months of age, they are susceptible to a specific and rapidly progressing form of tooth decay called Early Childhood Caries (ECC). Frequent bottle-feeding with liquids containing sugars, particularly during the night, can be an important cause of what is sometimes referred to as “baby-bottle syndrome”. Where possible, breastfeeding instead of bottle-feeding is recommended.

Parents should give their babies and toddlers only water between meals and brush their teeth twice a day with a smear of fluoride toothpaste.

Toothache is the number one reason for absenteeism from schools in the Philippines and many other countries.

Tooth decay in the USA is five times more common than asthma and seven times more common than hay fever.

In 2000, 51 million hours of school were lost in the USA due to dental problems.

in the fissures of a tooth or in the tight spaces between teeth. Root caries are more frequent among adults. Caries is treated by removing the decayed tissue and then placing a filling in the cavity to restore the tooth function.

On a global scale, most dental decay remains untreated due to unavailable or inappropriate oral-care services. Caries can be prevented by twice-daily toothbrushing with fluoride toothpaste, by applying fluorides, sealing the pits and fissures of molars, reducing the frequency of consuming sugars and carbohydrates, and by removing dental plaque (a film of bacteria that builds up on the teeth). Interventions related to personal behaviour and population-wide strategies must complement each other to effectively address the global burden of dental decay.

DENTAL PLAQUE

Dental plaque is a biofilm consisting of approximately 10,000 different types of bacteria, but only a few cause problems, and only one is mainly related to dental decay – Streptococcus mutans.

Saliva can protect against caries by dilution and elimination of bacteria and sugars, by buffering bacterial acids, and remineralisation of damaged tooth surfaces.

Patients with dry mouth (xerostomia) usually suffer from severe caries.

Health Actions • Cut down on sticky, sugary foods and soft drinks.

• Avoid unhealthy snacks between meals.

• Brush twice a day with a fluoride toothpaste.

• Chew sugar-free gum after snacks.

• Visit the dentist regularly.

ooth decay (dental caries) is an ancient disease. Levels of caries rose during the 17th century and reached epidemic proportions in the 19th and 20th centuries. The FDI and WHO set Global Goals for Oral Health by the Year 2000, and over the last three decades caries rates dropped in high-income countries. Scientists believe that this improvement was mainly the result of the widespread use of fluoride.

As populations of low-income countries adopt a more affluent lifestyle, high in sugar consumption, dental decay rates rise. Generally, caries rates are highest in middle-income countries where sugar consumption is high but access to prevention and care is low.

Since 1938, tooth decay has been measured using an index known as

MAPPING DENTAL CARIES 5 Dental decay remains largely untreated and there are widespread inequalities both between and within countries.

DMFT, which records the number of decayed (D), missing (M) and filled (F) teeth (T). While DMFT is not the only measure and has limitations, the oral health status of populations is often summarised as a DMFT score (usually of 12-year-olds).

A DMFT score of 1.0 means that one of the 32 adult teeth is either decayed, missing or filled. Scores for individuals are full numbers, for populations they can have decimal values. The WHO maintains a global database for caries levels; the data collection, however, is incomplete and not up to date due to the complexity of undertaking national surveys or different health-system priorities. Accurate data about dental decay is important for projecting the future disease burden.

Calculus (tartar) is a hard deposit on the tooth surface, typically on the inner surfaces of the lower incisors, but also on other teeth. It develops from dental plaque that hardens through minerals from saliva and becomes so hard that it cannot be removed with a toothbrush.

Calculus itself does not cause gingivitis, but the bacteria living in and on it can do so.

Calculus accumulation can be controlled and prevented by regular brushing, but once formed it can be removed only by an oral health professional.

MEXICO

Measuring gum disease and oral hygiene There are several ways of measuring the prevalence, severity and impact of gum diseases, including the assessment of: • bleeding • pocket depths • whether or not teeth are loose • the presence and severity of dental plaque.

The Community Periodontal Index of Treatment Needs (CPITN), developed by the World Health Organization (WHO), is one of the indices used to measure these aspects in population surveys.

However, many other indices are used as well, making comparisons between different surveys difficult.

um (periodontal) diseases include a range of inflammatory diseases of the tissues that support the teeth (periodontium). When the gums are involved, the disease is called gingivitis. If the deeper connective tissues and supporting bone are involved, it is called periodontitis.

Gingivitis, showing as swollen, red and bleeding gums around the teeth, heals with good oral hygiene and removal of dental plaque. Periodontitis and loss of attachment (“pockets”), however, can only be stopped but not restored. Left untreated, the disease can lead to increased tooth movement, abscess or even tooth loss.

The bacteria in dental plaque are the leading cause of gum disease. Other common factors of gum disease include smoking, diabetes, leukaemia and

HIV, hormonal changes associated with pregnancy, stress, and socioeconomic factors. Factors predisposing to plaque accumulation, such as calculus (tartar), defective dental fillings and crooked teeth also play a role.

Gingivitis is a very common disease, present in four out of five adults worldwide. Gum diseases include a number of distinct diseases with specific characteristics. In general, the link between gum disease and systemic health is the strongest of all oral diseases. Subject to intensive worldwide research, gum diseases have been linked to an increased risk for heart disease, premature and low-weight birth, and can influence the severity of diabetes.

Oral cancer often first shows up as a visible or palpable lesion of the lip, tongue, throat (pharynx) or other oral soft tissues; there may be pain, difficulty in eating, swelling, bleeding or ulceration. Tobacco use, especially when combined with alcohol consumption, is the major risk factor for developing oral cancer, together with poor diet and vitamin deficiency, viral infections, genetic disposition and other factors. Smoking is associated with about 75 per cent of oral cancer cases. Oral cancers are predominantly squamous cell carcinomas.

Quitting all tobacco products greatly reduces the risk of developing oral cancer. Dentists and other oral health professionals can help by offering tobaccocessation counselling.

Similar incidence rates of oral cancer may result in dramatically different case numbers, depending on population size. In 2002, India: female incidence rate 7.5 = 20,609 cases Namibia: female incidence rate 7.2 = 40 cases

In 2002, more than 400,000 cases of oral cancer were diagnosed worldwide. The risk for oral cancer is 15 times higher when the two main risk factors, tobacco use and alcohol, are combined.

NEW ZEALAND

Health Actions The clinical diagnosis is often confirmed by a biopsy of a suspected lesion and, if possible, the cancer is surgically removed. Radiation and chemotherapy can help in advanced cases. A dentist or other trained medical professional can perform a painless visual oral cancer screening in less than five minutes. If oral cancer is found at a very early stage there is a high chance of survival. However, as it is often diagnosed at a later stage, the average 5-year survival rates of oral cancer patients are only around 50 per cent.

• Reducing tobacco and alcohol use keeps your oral cancer risk low.

• If you have sores, white or dark patches, unusual bleeding or pain in your mouth or neck that persists for more than two weeks, see your dentist. Early detection will increase your chance of survival.

Noma affects mainly children up to six years old, often when they are being weaned at around the age of three.

oma is a rapidly spreading gangrene that starts in the mouth and disfigures the face, sometimes within days, consuming both soft tissue and bone.

The disease affects mainly children and, if left untreated, as noma usually is, is fatal in 80 per cent of cases. Children with noma are often hidden by their families due to social stigmatisation or, if they survive, live a life of permanent extreme disfigurement and handicap.

The World Health Organization estimates that 140,000 people, mostly in the poorest regions of Sub-Saharan Africa but also in Asia and South America, are affected. It is difficult to estimate the number of new cases, but a recent study by WHO/AFRO calculated about 42,800 new cases in one

Noma is a neglected, deadly and disfiguring disease of poverty, affecting mainly children.

WHO STRATEGY AGAINST NOMA

The NoNoma Federation is a coalition of more than 30 nongovernmental organisations united in the fight against noma.

Together with the WHO and the FDI, it organised the first World Noma Day on 22 May 2008 to raise awareness of the disease.

year in 21 Sub-Saharan Africa countries as a worst-case scenario.

Noma is a disease of extreme poverty and indicates general neglect, malnutrition, and lack of hygiene. Recently, eastern and southern African countries reported new cases of noma among HIV-infected children and adults, highlighting the significance of a compromised immune system in the disease process.

In 1998, the WHO established a Global Action Programme against Noma, supporting countries in their fight against the deadly disease. Treatment of noma is possible but requires complex interventions, starting with rehydration and improved nutrition, followed by antibiotics and, if necessary, plastic surgery. Emphasis should therefore be put on prevention.

More than ever, the common risk factors approach is the key to the elimination of noma. Fighting noma means also fighting malnutrition, measles and other infections, improving hygiene and, most importantly, fighting poverty.

For every two people put on antiretroviral drugs, another five become newly infected.

bout half of HIV-positive people develop oral fungal, bacterial or viral infections early in the course of the disease. Oral lesions such as candidiasis, herpetic ulcers and Kaposi’s sarcoma (a cancer often seen in association with HIV infection, but otherwise rare) are among the first symptoms of HIV infection. All these conditions cause pain, discomfort, eating restrictions and provide a constant source of opportunistic infection.

Despite many promising developments and global efforts to address the HIV/AIDS pandemic, the number of people living with HIV continues to grow. The most striking increases are seen in East Asia, Eastern Europe and Central Asia. In many regions of the world, new HIV infections are concentrated on 15–24 year olds.

Fungal infection (candidiasis) on the palate as sign of HIV/AIDS.

HIV-positive adults and children live, continues to bear the brunt of the global epidemic.

Early detection of HIV-related oral lesions can be used to diagnose HIV infection, monitor the disease’s progression, predict immune status, and can result in timely therapeutic intervention. The treatment and management of oral HIV lesions can considerably improve wellbeing. Oral examination is quick and inexpensive. In addition, oral health services and professionals can contribute effectively to the control of HIV/AIDS through health education and health promotion, patient care, effective infection control, and surveillance. However, most of those with HIV do not have access to these services, if they are offered at all.

Health Action • Know your HIV status so that your dentist and physician can provide appropriate health care.

If lip and palate clefts are properly treated by surgery, complete rehabilitation is possible.

left lip and cleft palate are the most common types of congenital birth defects. Factors such as genetic predisposition, poor nutrition, smoking, alcohol and obesity during pregnancy increase the risk of birth defects, which can result in many different forms of clefts.

Treatment of the deformity is necessary to restore normal eating, speaking and appearance, and to avoid social stigma. If left untreated, serious complications and even death may result. Children affected require multiple surgeries, frequent follow-up and appropriate facilities, little of which is accessible or affordable for many children affected in low- and middle-income countries. Specialised NGOs sometimes assist in making such services available.

Every year, 5 million teeth are knocked out of the mouths of children and teenagers during sports in the USA.

TRAUMA 11 Boys are almost twice as likely to experience dental trauma as girls.

Head and tooth trauma are important public health problems worldwide.

The highest risk of tooth trauma is associated with football (soccer), handball and ice hockey.

When a tooth is knocked out completely, keeping it either in a glass of milk or in your mouth under the tongue can help maximise the chance of reattachment. See a dentist immediately!

RISK FACTORS FOR DENTAL INJURIES • large overbite (protrusion of front teeth) • traffic and bicycle accidents • contact sports

The cost of dental trauma treatment in Sweden is estimated at US$3.3 – US$4.1 per person per year.

• violence • falls • piercing of tongue and lips • physical abuse (children/elderly)

M

ost traumas to the jaws and teeth are associated with sports, unsafe environments (schools and playgrounds), traffic accidents or violence. The costs of treatment and follow-up care for trauma patients is significant; thus trauma is an important public health problem worldwide.

Head trauma can result in tooth chipping, fracture of the tooth or supporting bone, as well as tooth loss or dislocation. In many cases the long-term survival of the tooth is at risk.

Traffic accidents and violence are the most important risk factors for fractures of the jaw and facial bones, which are usually fixed by the surgical insertion of titanium plates.

Health Actions • Wear a mouth guard during contact sports.

• Wear a helmet during exposed transportation and for accident-prone sports (motorcycles, skates, biking, etc.).

• Always wear a seatbelt.

ral diseases impact on individuals, communities, society, health systems and the economy. It is difficult to calculate the full economic impact of oral diseases and no comprehensive international statistics exist in this context.

The World Health Organization (WHO) estimates that oral diseases are the fourth most expensive diseases to treat. Another study showed that if treatment were available, the costs of treating the dental decay of children alone would be greater than the total health care budget of many low- and middle-income nations. However, prevention and early treatment substantially reduce overall costs.

In addition to the direct costs of treatment, there are indirect costs to

Simple tooth extraction consider. In the USA alone, 2.4 million days of work and 1.6 million days of school were lost due to oral disease in 1996. Additionally, absenteeism from school and work can lead to limited academic achievement and reduced employment opportunities. On the other hand, dentistry and the related health care industry generate significant contributions to a country’s employment market and economy as a whole.

Dental care is the most common reason for medical tourism, where patients travel to other countries for cheaper treatment. Yet, for the majority of health systems in the world, appropriate dental care and coverage for the entire population are not realistic because of low expenditure on health in general and other, more pressing, health priorities.

ral diseases are traditionally measured with clinical or statistical indices, but measuring their significant negative impact on the quality of life is equally important. The impact of oral diseases is higher in poorer countries and for populations with lower socio-economic status, mainly due to the prohibitive costs of treatment.

Oral diseases can affect self-esteem, social interactions and communication. They can also disrupt crucial functions such as chewing, swallowing, speaking and sleeping, leading to difficulties in concentration and missed days of school and work.

condition is a public health problem or not. For some oral conditions, such as birth defects or noma, the impact for the individual affected is very high, while the overall effect on society is not; for other diseases, such as dental decay, the cumulative impact on society is substantial.

Dental pain and toothache are commonly ranked among the worst pain imaginable. There is no comprehensive data on the prevalence of oral pain, but untreated dental caries is the most common reason for dental pain, particularly affecting children. Pain resulting from oral diseases leads to a complex sequence of related issues: the need to pay for treatment, the loss of productivity and the downward cycle of health problems, poverty and deprivation.

Further improvements in oral health and a reduction in oral health equalities will only be secured through the adoption of oral health promotion policies based upon the common risk factor approach. â&#x20AC;Ś Isolated, individualistically focused oral health education interventions are ineffective, wasteful of limited resources and may increase inequalities.

C

hronic diseases, including oral diseases, are of long duration, generally progressing slowly and usually non-communicable. A small number of common causes (risk factors) are responsible for most chronic diseases. Major risk factors, such as tobacco use, physical inactivity and a diet high in fat, salt and sugar, contribute to a range of chronic diseases, such as obesity, diabetes, cardiovascular diseases and oral diseases.

The risk factors for chronic diseases compound over time, resulting in higher levels of chronic disease as age increases. Poverty and chronic disease are linked into a vicious cycle; chronic diseases can exacerbate poverty and the poor have greater exposure to risk and less access to health services.

RISK FACTORS 14

High consumption of sugar is the number one risk factor for tooth decay and diabetes. Almost 80% of diabetes deaths occur in low- and middle-income countries.

A range of oral and other chronic diseases can be reduced, or even prevented, when the key risk factors responsible are addressed.

Tobacco use is the most important risk factor for six out of the nine leading causes of death.

Supportive policies, a healthy environment and individual behaviour contribute to reducing the major risk factors. Many risk factors are results of broader determining factors, such as lifestyle, socio-economic status, or living conditions.

A dramatic increase in most chronic diseases, such as diabetes and obesity, has been observed in low- and middle-income countries. It is important to monitor and collect data about risk factors to predict future disease burdens and plan health services accordingly.

The following pages look in more detail at a few major common risk factors for oral health: sugar, tobacco, and socio-economic status.

The global confectionary market is expected to reach US$107 billion by 2010.

ugars are carbohydrates and, like all carbohydrates, provide an essential source of energy in a balanced diet. Sugars primarily come from sugar cane, corn and sugar beets, but also occur in fruit, honey and many other sources.

The frequency and amount of sugar consumption is directly related to increased risks of tooth decay, type 2 diabetes and obesity. Oral bacteria, such as Streptococcus mutans, metabolise sugars into lactic acid, which can cause demineralisation of tooth tissue and tooth decay. This is why the frequent consumption of snacks and beverages containing high sugar levels increases the risk of tooth decay.

The food and associated industries spend a lot of money on promoting and advertising sweetened products. Carbonated beverages (also known as soft drinks, fizzy drinks, or soda pop) contain large amounts of sugar, have very little nutritional value and replace other, more nutritional fluids, such as milk. These products are heavily advertised, are cheap, and are sold in virtually every country in the world. Diet soft drinks and sugar-free gums contain sugar substitutes. They may reduce, but do not eliminate, the risk of tooth decay.

Health Actions • Limit the consumption of sugary foods and drinks, especially between meals.

• Snacks and sweets labelled as “sugar-free” are usually less harmful to oral health.

sing tobacco has a great impact on oral health and is one of the key risk factors for oral disease. Among the most significant effects of tobacco use are oral cancers and pre-cancers, increased severity and extent of periodontal diseases, and poor wound healing. Tobacco is dangerous in all its forms – manufactured cigarettes, roll-your-own, cigars, pipes, snuff, chewing tobacco and paan.

There are currently an estimated 1.4 billion smokers in the world and the number of smokers continues to increase. The World Health Organization (WHO) estimates that by 2030 there could be about 1.6 billion smokers.

Tobacco use killed 100 million people worldwide in the 20th century and the WHO predicts that it could kill 1 billion more in the 21st century unless

governments act now to dramatically reduce it.

Tobacco use is the second biggest killer in the world, causing 5.4 million deaths a year. Cigarettes kill half of all lifetime users, half of whom die in middle age (35–69 years), losing an average of 20 to 25 years of life.

Oral health professionals play an important role in helping their patients stop smoking. The FDI World Dental Federation and the WHO promote an active role for oral health professionals and their associations in tobacco control. Dentists and their team are as effective as other health professionals at cessation counselling. In order to be successful role models, health professionals need to quit smoking and make all health facilities smoke free.

Health Actions • Reducing or quitting tobacco use will improve your oral health. If you cannot do this, remind your dentist to check for oral cancer symptoms.

• Advocate for smoke-free environments.

s the WHO Commission on Social Determinants on Health (2008) expressed so clearly: “In countries at all levels of income, health and illness follow a social gradient: the lower the socio-economic position, the worse the health.” Such social gradients are present in oral health and disease. They are seen in the unequal distribution of gum disease, tooth decay and oral cancer across countries of different incomes, and also occur within countries, with those occupying the lowest socio-economic positions having the highest levels of oral diseases.

Many of the factors determining oral health are found outside the mouth, including income, education, housing and sanitation, gender, ethnic origin, availability and access to health services.

SOCIO-ECONOMIC STATUS 17 Socio-economic status is a key risk factor for many oral diseases, and significantly determines both general and oral health.

IMPACT OF POVERTY Compared with their compatriots of high socio-economic status, those on a low income and of low educational attainment, including immigrants and ethnic minorities, experience: •

fewer dental visits

•

fewer fillings

•

more missing teeth

•

higher tobacco consumption

•

higher rates of oral cancer

•

Dental decay rates are highest in middle-income countries experiencing economic transition. People are able to increase their income and their ability to purchase sweet foods, but may not be exposed to populationwide preventive measures such as fluoridation, or have access to affordable dental care.

Simple, proven and cheap population interventions, such as fluoridation, make systematic disparities in oral health avoidable, and their continuation unfair. The WHO Commission on Social Determinants on Health concluded powerfully that “reducing health inequities is … an ethical imperative.

Social injustice is killing people on a grand scale.”

O

ral diseases are largely preventable. Personal behaviour, lifestyle and oral care habits are important factors for retaining a healthy mouth throughout a lifetime. Behaviour patterns are determined early in life, thus most health education efforts focus on children. Parents and peers are crucial role models in this context.

There are a few key preventive behaviours that can secure good oral health: brushing twice daily with a fluoride toothpaste; a varied and balanced nutrition low in sugary foods and soft drinks; not smoking or chewing tobacco; consuming alcohol within recommended safe limits; wearing protective mouth guards if participating in contact sports; and visiting an oral health professional for check-ups and preventive advice.

BEHAVIOUR AND CHOICES 18 In many parts of the world miswak (chewing sticks) are used to clean teeth. They are mainly obtained from the Arak (Salvadora persica) or Neem tree (Azadiracta indica). They have antimicrobial properties and can be as effective as using a toothbrush.

Oral diseases are preventable by appropriate behaviour, which is reinforced and encouraged by public health policies and health promotion.

FAQS ABOUT ORAL HEALTH

Q A Q A Q A Q A Q A

How often should I brush my teeth?

Evidence shows that brushing twice daily with a fluoride toothpaste is sufficient for good oral health. If you wear a denture, clean it regularly.

In 2003, the toothbrush was selected as the number one invention Americans could not live without.

Should I use dental floss?

There is moderate evidence to recommend flossing to prevent dental caries and little or no evidence to recommend flossing to prevent gum disease.

Should I use a mouth rinse?

Only a small percentage of the bacteria living in the mouth cause dental decay or gum disease, the rest are harmless. Antibacterial rinses should not be used on a daily basis unless prescribed. Alcohol-free rinses containing fluoride are more likely to be beneficial.

Should I use a manual or electrical toothbrush?

There is evidence showing that a rotation-action electrical toothbrush removes more plaque than a manual toothbrush. Additionally, some electrical brushes have a timer, which can help encourage tooth brushing for the recommended time. But it is also possible to keep the teeth clean with a manual toothbrush.

What kind of toothpaste should I use?

Only use toothpaste that contains fluoride. Brushing your teeth with a non-fluoride toothpaste does not protect your teeth from dental decay.

However, knowledge about even simple personal oral care measures should not be taken for granted. Dental teams and health professionals in general have the professional responsibility to help their patients acquire the knowledge and skills to maintain good oral and general health. All recommendations on oral hygiene must be based on the best possible evidence and take the individual situation into account. In the long term, positive oral health behaviour is only sustained if it is supported by additional public health actions that tackle the broader social and environmental causes of poor oral health.

or over 60 years, fluoride has been crucial in strategies to prevent dental caries. Fluorides are compounds containing the element fluorine, the 13th most abundant element in the Earth’s crust. Fluorine occurs naturally in rock, soil, water, plants and animals.

In the early 1940s, the relationship between fluoride levels in drinking water and dental caries was established. Early programmes to artificially adjust the level of fluoride to optimum levels in public water supplies (water fluoridation) resulted in a reduction in decay of around 50 per cent.

Many methods of fluoride delivery are available. In addition to community measures such as water, salt and milk fluoridation, there are self-applied measures including fluoride toothpaste and rinses, as well as professionally

applied or prescribed measures such as varnish, gel and tablets.

Fluorides prevent caries topically by inhibiting bacterial metabolism (acid production) in dental plaque, inhibiting demineralisation of teeth, enhancing remineralisation (repair) and making the teeth more resistant to future acid challenge.

Exposure to higher than recommended levels of fluoride during tooth development (mainly between birth and four years of age) might cause dental fluorosis. This condition is often not noticeable; only the rare and severe forms show brown spots and discolouration of teeth. Older children and adults are not at risk. If applied at recommended levels, fluorides are a safe and effective way of reducing the global burden of dental decay.

ater and salt fluoridation are not available to the majority of the world’s population, therefore fluoride toothpaste remains the most significant method of fluoride dissemination globally.

Fluoride toothpaste is the most rigorously evaluated means of fluoride use, with over 100 clinical trials confirming its efficacy in preventing tooth decay. There are huge differences in the affordability and quality of fluoride toothpaste available worldwide.

Toothpaste came into general use in the 19th century and fluoride was first added to toothpaste in 1914. Joseph Muhler and his team at Indiana University developed the first effective fluoride toothpaste to prevent dental caries, which led to the first commercially available fluoride

FLUORIDE TOOTHPASTE 20 In 1960, Crest® became the first brand of toothpaste to receive an endorsement from the American Dental Association for being effective in preventing tooth decay. In 2009, 51 fluoride toothpaste brands marketed in the USA bore the ADA seal.

Combined use of fluoride toothpaste and fluoridated water is more effective in preventing caries than either used alone. There is no harm or risk of overdose if both fluoride sources are used.

The widespread use of fluoride toothpaste has been recognised as the single most important reason for the decline of dental caries.

Children under the age of six should only use a pea-sized amount of fluoride toothpaste and be supervised to minimise the amount swallowed.

toothpaste, sold as Crest®, in 1955. By the 1990s, more than 90 per cent of the toothpaste sold in the USA, Canada, and other high-income countries contained fluoride.

Fluoride toothpaste is available in a number of formulations both as a paste and gel. Sodium fluoride (NaF) and sodium monofluorophosphate (Na2PO3F) are the most common forms of fluoride used in toothpaste.

Stannous and amine fluoride formulations are also marketed. Most toothpastes contain between 1,000 and 1,450 ppm (parts per million) of fluoride, although low-fluoride formulations for children exist.

Health Actions • Brush your teeth twice a day with a toothpaste containing fluoride (best after breakfast and before going to bed).

• Spit, but do not rinse after brushing to increase the anti-caries effect.

DEBATE Some countries have banned amalgam as a filling material due to concerns about patient safety and environmental concerns relating to the mercury component.

Major international scientific and health bodies, including the World Health Organization, confirm that dental amalgam is a safe, reliable and effective restorative material.

In the USA, it is estimated that 30–40 million people avoid dental treatment every year due to anxiety and fear.

Crown: Also known as a cap, involves reducing a tooth so that a covering made of metal, porcelain fused to metal, or ceramics, made by dental technicians, can be permanently fixed to restore tooth function.

In 2007, about 43,000 UK patients travelled abroad for dental treatment, each spending an average of US$6,000.

Filling: Involves removing caries and placing a restoration (consisting of an amalgam, ionomer or composite resin) into a prepared cavity in a tooth.

Extraction and surgery: Tooth removal, draining of abscesses, and other surgical procedures.

Preventive treatment: Includes preventive advice and action such as tobacco cessation, dietary advice, fissure sealants etc.

ental treatment, using a broad range of available restorative, corrective and cosmetic procedures, is traditionally a core activity of dentists. Interventions include check-ups, x-rays, tooth cleaning, tooth extraction, different types of fillings, veneers, crowns, bridges, root canal treatment, partial or full dentures, implants, complex rehabilitation of function and aesthetics, prevention and treatment of oral infections.

Orthodontics (braces, retainers, etc.) and cosmetic dentistry are also options for patients able to afford the costs.

Dental implant: A titanium post is implanted in the jaw bone to attach a crown or anchor a denture.

The US market for dental implants is estimated to be US$1 billion in 2011.

Gold is the most expensive filling material and has been used in dental fillings for thousands of years.

fear and avoid regular check-ups. The dogma of two check-ups a year has been abandoned for a more flexible schedule based on individual need.

Dental care is the most frequent reason for seeking health care abroad.

Dental tourism is a growing trend, which involves people travelling to other countries for private dental care at a fraction of the cost of care in their home countries.

There are huge inequalities in dental care throughout the world.

Treatment is limited due to available resources, as well as affordability and accessibility for patients. Quality restorative oral care is only realistic for affluent, urban population groups, while rural, poor and deprived population groups lack access to even basic emergency care.

Left: Oral Urgent Treatment in Cambodia.

Below: Removing caries with a hand instrument prior to ART restoration.

The WHO Oral Health Programme recommends that: “Health authorities should strengthen the implementation of oral disease prevention and health promotion programmes rather than traditional curative care. Community-oriented essential care and affordable fluoride toothpaste should be encouraged.”

BASIC PACKAGE OF ORAL CARE WHAT IS OUT? Oral Urgent Treatment (OUT) is an on-demand service providing basic emergency oral care. The three fundamental elements of OUT are: • relief of oral pain • first aid for oral infections and dento-alveolar trauma • referral of complicated cases.

OUT can be provided by trained non-dentist personnel.

For nearly 20 years, Cambodia has successfully provided essential dental treatment in most rural areas by training community nurses.

Dentists help with training, and supervise and manage the programme.

WHAT IS AFT? Use of Affordable Fluoride Toothpaste (AFT) is one of the most important preventive measures in managing dental caries.

However, fluoridated toothpaste is often too expensive for disadvantaged groups in low- and middle-income countries to purchase. AFT programmes are designed to allow people to clean their teeth twice daily with affordable fluoridated toothpaste.

WHAT IS ART? Atraumatic Restorative Treatment (ART) is a caries management approach, consisting of a preventive (fissure sealant) and a restorative component (filling). ART can be performed inside and outside a dental clinic, as it uses only hand instruments and does not rely on electricity and running water. It causes minimal pain, minimises the need for local anaesthesia, and helps with cross-infection control.

In Tanzania, ART restorations accounted for between 8% and 20% of the total number of dental procedures carried out in 13 public dental clinics during a 31-month period following introduction of the approach.

ppropriate, accessible and affordable oral health care remains a remote aspiration for the majority of the world’s population. Oral health care using a technology-focused curative approach is unrealistic for most low-income countries.

The Basic Package of Oral Care (BPOC), developed by the WHO Collaborating Centre for Oral Health Care and Future Scenarios at the University of Nijmegen, Netherlands, is designed to better match the realities of low-income countries. The BPOC is a milestone, providing a conceptual framework for integration of oral health into Primary Health Care. This WHO-endorsed concept is based on modular components that can be adapted to the resources and needs of recipient communities.

The “Fit for School” programme in the Philippines provides for teacher-supervised daily tooth-brushing and hand-washing, and twice-yearly de-worming. Cost for material is US$0.50 a child per year. It reduces caries by 40% and reduces the progression of caries into the pulp by 60%.

Quantity of care needed

A Primary Health Care system that provides universal coverage is people-centred, has demand-led policies and programmes and integrates health into all policies (labour, environment, education, etc.). It is more likely to benefit a greater proportion of the population than traditionally designed health care services.

In settings with low resources, essential health packages pool high-impact interventions in a scalable, affordable and synergistic way. Focus should be on preventive actions, priorities allocated according to disease burden, and basic emergency care and pain relief. It is possible to target interventions to specific population groups. The elderly are likely to benefit most from treatment, while children will benefit most from prevention.

UN MILLENNIUM DEVELOPMENT GOALS The MDGs were agreed by all member states of the United Nations in 2000 in order to address the growing gaps in development between nations by 2015. The goals have a significant impact on the international health agenda, and oral health can be linked to all goals.

Global Goals for Oral Health In 1981, the WHO and FDI jointly agreed the Global Goals for Oral Health by the Year 2000. The target was a DMFT value of less than 3 for 12-year-old children. Although not all countries reached the goals, they catalysed action for oral health. New goals for 2020 were agreed in 2003.

ecause oral health and general health are related, oral care and prevention of oral disease must be an integral part of any health system. Oral health is a human right and requires appropriate provision for everyone. This goal is yet to be achieved and will remain a challenge for decades to come. Through the Global Goals for Oral Health by the Year 2000 many countries have proved that health targets can be reached, if priorities and political support follow population needs.

The Millennium Development Goals (MDGs), as well as many other international declarations, provide the platform for increased advocacy for improved oral health worldwide. International stakeholders, NGOs and the oral health care industry play an essential role in this context.

What is a Chief Dental Officer?

Many governments have a dedicated person for oral health matters, often called a Chief Dental Officer (CDO). As the principal dental advocate they are crucial in ensuring that oral health is integrated into the government's agenda, and that oral health is part of national health planning and health budgeting.

However, not all countries have a CDO, or the position is sidelined by lack of involvement and budgets.

World Oral Health Day World Oral Health Day was designated as 12 September by the FDI in 2007, in commemoration of the birthday of the FDI’s founder, Charles Godon, and in recognition of the Alma-Ata conference on Primary Health Care, which took place on that date in 1978. Every year, the day is an occasion to advocate for oral health worldwide.

During a Global Oral Health Workshop, convened by the FDI in 2003, the Ferney-Voltaire Declaration was adopted. It urges all concerned with health to work together in a network of formal and informal partnerships to reduce inequalities in health and to increase access to affordable oral health care by developing policies that focus on: “Improving living and working conditions, enabling people to adopt healthier lifestyles, encouraging communities to participate in every stage of the policy planning process, enabling all people to access an appropriate, locally determined, programme of basic oral health care that includes: relief of pain, promotion of oral health and the management of oral diseases and conditions.”

Oral health practice is broader than, but includes, the professional practice of dentistry. The specific practice of dentistry is a large and critical facet in this regard; but dentistry cannot be successful alone as it is not sufficient to resolve the challenges at hand. In many regards, it appears that the practice of dentistry may contribute as much to the problem as it has potential to participate in the solution.

Part 5 ORAL HEALTH WORKFORCE 65

Dental Assistant Dental assistants support the dentist in the surgery and help with administration; they normally work under the supervision of a dentist.

Dental Hygienist Dental hygienists focus on oral hygiene and education, application of preventive agents to teeth and gums, and procedures aiming at preventing tooth decay and periodontal diseases. In some countries they practise independently without the supervision of a dentist.

Training: 1–3 years Training: 1–3 years

A

team approach in dentistry, as in other health professions, has become more and more common in many countries. The dental team may include up to five different types of oral health professionals and is usually led and supervised by a dentist. Dental assistants (also called dental nurses), dental hygienists, dental laboratory technicians and dental therapists perform a range of complementary tasks.

National regulations determine the exact roles and duties of the five allied oral health professions, and ensure their proper training. Depending on community needs, available resources and local legislation, these roles vary from country to country, and not all professions exist in all countries.

There are no comprehensive international statistics covering these

THE DENTAL TEAM 24 Dental Therapist Dental therapists provide basic dental treatment such as extractions and simple fillings, as well as undertaking the tasks of hygienists. In some countries they practise independently without the supervision of a dentist.

Dental teams function in a variety of settings, ranging from high-tech clinics to simple community or field settings.

DEBATE Delegating basic tasks to lower-trained and non-dental personnel can increase access to care.

Only oral health professionals can provide quality oral health care.

Training: 1–4 years

New Zealand has an extensive system of School Dental Therapists. Treatment costs for children up to the age of 12 are covered by the state.

Dentistry is defined as the “evaluation, diagnosis, prevention and/or treatment of diseases, disorders and/or conditions of the oral cavity, maxillofacial area and/or the adjacent and associated structures and their impact on the human body.”

Dental (Laboratory) Technician Dental technicians are responsible for manufacturing crowns, bridges, dentures, and other dental prosthetics following a prescription from a dentist. In some countries they are allowed to manufacture and fit dentures independently, without involving a dentist (then called a “denturist”).

Training: 1–3 years (+ postgraduate if specialised)

professions, but it can be estimated that their total worldwide number is at least twice the number of dentists, bringing the total number of “dental workers” to about 3 million worldwide.

Illegal or “quack” providers carry out routine dental care in many countries, sometimes outnumbering registered dentists. These illegal practitioners typically lack proper training, tools, cross-infection controls or anaesthetics, resulting in low-quality, ineffective and often dangerous, counterproductive care. However, for many they are the only available or affordable providers of oral care and pain relief. In the context of task shifting, new, more flexible, workforce models are being developed to better address the needs of resource-poor or remote communities.

The dental team aims to prevent oral disease and ensure the best possible quality of oral health care.

entists are health care professionals who focus on the diagnosis and treatment of diseases that affect the mouth and teeth. Dentists and dental teams are usually an integral part of health services, providing education, prevention, supervision and management. Dentists work in a variety of settings including academia, hospitals, private practices, community clinics, research institutes, private companies and the public health sector. Dental councils or equivalent institutions register and license dentists, provide ethical guidance and quality control. The dentist-topopulation ratio is a rough indicator of service availability, and a higher number of dentists does not necessarily result in the improvement of all aspects of oral health.

There is a significant shortage of dentists around the world, particularly in low-income countries. Practitioners tend to cluster in affluent urban areas, leaving rural areas or less affluent populations with a serious lack of access to quality care. Illegal practitioners, many of whom lack formal training and appropriate equipment, often fill the gap. Unfortunately, although such illegal services can be harmful to patients they may provide the only available or affordable relief.

Adding to the shortage of dentists is a growing “brain drain”, with oral health professionals migrating away from their country of origin.

he global oral health workforce is affected by many factors: emerging dental education institutions; demographic developments; evolving science; economic pressures in the private sector; changing public health priorities. In many high-income countries a large proportion of dentists will leave active work and retire in the coming decade without being replaced by new graduates, resulting in a decrease of active dentists.

On the other hand, dentist numbers are steadily increasing in many middle-income countries.

The overall shortage and unequal distribution of dentists is complicated by a growing trend of “brain drain”, as oral health professionals migrate from their country of origin to work in a different country, often attracted

Governments and professional organisations try to address the problems related to international migration with ethical codes, calling for equal working conditions for all health professionals and discouraging active recruitment.

The relations among members of the dental team in many countries are not well defined, making matters of independent practice, supervision, and delegation a constant topic of debate. In some countries innovative models of task-shifting from highly trained dentists to other oral health professionals with less extensive training are implemented to improve access to care and lower costs, particularly in rural or remote areas.

Dental degrees require four to six years of university study and are expensive, for the country, the institution and the student. Generally, dental school entry requirements and training are comparable to those of medical schools.

Dental education covers theoretical and practical training, including anatomy, physiology, biochemistry, pathology, behavioural sciences and dental materials science, as well as clinical skills.

Established in 1920, its mission is: to advance research and increase knowledge for the improvement of oral health worldwide; to support and represent the oral health research community; and to facilitate the communication and application of research findings. IADR emphasises transforming science and knowledge into practice, creating tangible benefits, particularly in low-income countries.

Are we focusing enough ... attention on fundamental, cross-cutting, and far-reaching ... approaches to the control of oral disease globally? Or are we ... dealing with them in compartments ... without attacking the underlying, fundamental issues?

The 2007 World Health Assembly adopted Oral Health: Action Plan for Promotion and Integrated Disease Prevention, a significant milestone for global oral health. WHO policies, such as global strategies on diet and nutrition, tobacco, and Primary Health Care, need to be integrated with national oral health planning. Other elements of the action plan include workforce planning, promoting fluoride, strengthening data collection for effective national planning, as well as translation of evidence into action and public health practice.

his Oral Health Atlas provides a global view of oral health and – as the subtitle of the book suggests – maps a neglected area of international health. The degree of neglect is visible in many areas and dimensions, predominantly in the huge inequalities in disease burden, exposure to risk factors and access to care between and within countries.

The scorecard is intended to assess the current situation, provide a baseline, encourage debate of oral health issues, and highlight areas that require urgent and sustained action.

Based on a concept of a scorecard for global public health (Beaglehole & Bonita, 2008), the authors of this atlas have used their informed judgement to assess the situation relating to important oral health areas. The scores

Evidence-based interventions for all major oral diseases exist, but they are not available or implemented in the majority of countries.

CRITERIA FOR SCORING Evidence for action Data: Are current data available for measuring the burden of oral disease and for tracking trends?

Interventions: Do cost-effective interventions exist to address the disease burden?

Leadership for oral health Agenda: Is oral health firmly on the health agenda?

Advocacy: Is there strong and sustained evidence-based pressure for action?

Resources Financial resources: Are adequate resources allocated to oral health?

Human resources: Is the oral health workforce sufficient and appropriate?

Health systems Prevention: Do health systems give due attention to prevention of oral diseases?

Treatment: Do health systems provide appropriate curative treatment?

Integration: Is oral health integrated with other health areas in national health plans? allocated reflect the current status in each of these areas. Although the division into high-, middle- and low-income countries is a generalisation, it nevertheless highlights the very different realities and challenges; the framework should ideally be used to develop scorecards for every country.

Improving any area of global health requires evidence for action, leadership, resources, and appropriate health systems. The scoring criteria chosen address these areas by looking at more detailed aspects for each of the four main areas against four important disease areas â&#x20AC;&#x201C; dental decay, periodontal diseases, oral cancer and oral manifestations of HIV/AIDS. The scores presented do not show a precise measurement, but are indicative and will hopefully stimulate discussion.

he milestones featured on this page should not be taken as real facts, but rather as informed speculation on what is to come over the next 40 years.

Populations today generally enjoy better oral health than their forebears a century ago. However, the fact that not all population groups have achieved the same level of oral health and well-being is still a major challenge.

In high-income countries tooth decay, gum disease and toothlessness rates will fall, while oral cancer survival rates will improve as prevention, oral hygiene and early detection get better. Tooth decay will rapidly increase in low- and middle-income countries as people consume more sugar, have low

The number of deaths resulting from communicable conditions is expected to continue to decline, while the number of deaths from non-communicable conditions, including most oral diseases, is expected to rise, resulting in a greater burden to public health in the future.

The FDI will celebrate its 150th anniversary in 2050.

exposure to fluoride and lack access to appropriate oral health care.

High-income countries will see a growing elderly population who will require more care than the generations that follow them.

Focusing on prevention is the only realistic way to address the epidemic of oral diseases worldwide. To help ease this burden, oral health products, such as toothpaste, will be exempted from taxes and sold in smaller quantities, to increase their affordability. Innovative ways of delivering fluoride will make it even easier and more effective to prevent dental decay. The market for oral health products and treatment will skyrocket as millions of new consumers rise out of poverty, particularly in India and China.

There is no shame in not knowing; the shame lies in not finding out.

COMMENTS ON DATA Many people, even in public health, do not appreciate the value of sound and reliable health statistics. Others, on the contrary, overemphasise the need to have statistics before taking any action. Both extremes are probably not appropriate; at times, however, it is difficult to find a realistic middle ground.

Collecting data on health is a complex undertaking that requires appropriate and agreed indicators, a health system strong enough to undertake surveys or data reporting on a regular basis, as well as political support to allocate sufficient budgets to statistics. While much progress has been made in general health and health systems performance data collection, particularly those related to measuring the Millennium Development Goals, much remains to be done in the areas of health workforce and especially in all areas related to oral health. Initiatives from WHO, the European Union and others to integrate appropriate oral health indicators in routine health data surveys are welcome steps in the right direction that have yet to be implemented at a national level in many countries. Including key oral health data in international health statistics is a task still to be tackled on a broader scale.

The maps and charts of the Atlas reflect averages from disparate data sets of varying coverage and quality.

Averages, unfortunately, obscure significant differences from the mean and may paint a rosier picture for some countries than may exist for significant portions of their respective populations. Those averages may consequently also obscure areas for future data collection and research, as well as associated recommendations for action.

Some of the data sources used throughout this atlas are outdated, unreliable or not comprehensive in coverage.

Researching the data revealed astonishing gaps in data availability and quality, ignorance of existing appropriate indicators, or simply absence of any data at all. On the other hand, for many countries or regions of the world, data ranging from acceptable to very good exists. In order for this gap to be addressed, significant political and financial efforts are required. However, despite the shortcomings of some underlying data, the sources used are generally the best available; and the maps highlight key issues in oral health that require international attention and action.

Although all possible efforts were made to present the most recent and reliable data, errors and omissions will occur. We welcome suggestions and comments on specific data aspects and accuracy, but encourage all to read the following remarks first, outlining the source and limitation of specific data. After all “No one loves the messenger who brings bad news”! (Antigone, Sophocles, Greek tragedian, 496–406 BCE).

5 MAPPING DENTAL CARIES Despite dental caries being the most widespread chronic disease on the planet, the lack of reliable data are striking.

The WHO Oral Health Country/Area Profile Programme, used for the map, is the only international source of data, yet 41% of data entries for caries are 10–19 years old, 16% older than 20 years, while only 8% of datasets are less than 5 years old. Furthermore, many datasets do not rely on a national survey and are thus not representative for an entire country, but rather present data from only one region, city or village. Differences within countries, i.e. between rural and urban or different socio-economic strata, are not reflected at all in this data. The focus of the data is on 5–6-year-old or 12–15-year-old children; while data for other age groups are not comprehensively

104

recorded. In addition, there is a general critique of using the DMFT index to measure dental caries (for more details see: Fejerskov O, Kidd EAM. Dental caries: the disease and its clinical management. Oxford: Blackwell Munksgaard; 2008, p126). For some countries (Serbia, Mozambique, Montenegro, Democratic Republic of Congo), the WHO database only gives a DMFT range, and the map colour is determined by the average value.

The graph indicating percentages of the different DMFT components according to country income group is a modified version of the data given by Baelum et al. 2007 (Baelum V, van Palenstein Helderman W, Hugson A, Yee R, Fejerskov O. A global perspective on changes in the burden of caries and periodontitis: implications for dentistry. J Oral Rehabilitation. 2007;34:872-906).

6 GUM DISEASES Periodontal disease is usually recorded using the (CPITN) index, which was too complex to be used in this publication. We therefore included data on total toothlessness (edentulousness/edentulism) as a proxy for the impact of gum disease, well aware that a number of other factors contribute to tooth loss. The data presented are based on the WHO Oral Health Country/Area Profile Programme, which is even more limited with regards to periodontal disease than for dental caries. Data are only available for 127 countries, and information on more than 60 is older than 10 years. As described in the comments for dental caries earlier, limitations apply to national representativeness, age groups and socio-economic differences within countries. It should also be noted that the data only refer to complete edentulism, although missing a few but not all teeth can have a significant impact on quality of life too.

7 ORAL CANCER Male and female age-standardised incidence and mortality rates for oral cancer were sourced from International Agency for Research on Cancer, which is part of the WHO system. Their GLOBOCAN database uses the latest available estimate figures for the year 2002. However, although the populations of the different countries are those estimated for the middle of 2002, the disease rates are not those for the year 2002, but from the most recent data available, generally 2–5 years earlier. Full details of the limitations of the GLOBOCAN 2002 data are available at: http://www-dep.iarc.fr/globocan/database.htm The GLOBOCAN 2002 database uses the ICD10 code C00-C08 to define oral cancer. This definition includes the following cancer localisations: lips, tongue, floor of the mouth, gingiva, palate, salivary glands and other oral mucosa areas.

8 NOMA There is a severe lack of global data on noma, due to the specific characteristics of the disease. The only figures accessible are the number of noma cases referred for treatment, which are dependent on the existence of a system of medical records for each patient. In 1994, the WHO organised an expert consultation using the Delphi method. It was estimated that only 10%–15% of noma cases were referred for treatment and that the mortality rate was 80%–90%. The total number of cases worldwide per year was estimated at 140,000.

The inset map of Africa gives the latest available figures from 2006. The data are based on a survey undertaken

by WHO/AFRO (unpublished) using reported numbers from 21 Sub-Saharan countries, and estimating the incidence assuming a scenario of 10% referred cases and

90% mortality rate; thus following the methods used by Fieger et al. (Fieger A, Marck KW, Busch R, Schmidt A. An estimation of the incidence of noma in north-west Nigeria.

Trop Med Int Health. 2003;8:402-407) and the WHO Report on Noma (World Health Organization. Noma today: a public health problem? Report of an expert consultation organised by WHO using the Delphi method (WHO/MMC/ NOMA/98.1). Geneva: WHO; 1998). The resulting number of 42,800 cases in 2006 may be an underestimation, since only 21 countries of the WHO/AFRO region participated and key countries affected by noma, such as Sudan and Somalia, are not part of WHO/AFRO. 9 HIV/AIDS The map is based on the latest available data from UNAIDS and shows the estimated percentage of the population aged 15–49 who were HIV-positive in 2007 (Joint United Nations Programme on HIV/AIDS (UNAIDS). Report on the global AIDS epidemic 2008. Geneva: UNAIDS; 2008) 10 BIRTH DEFECTS The incidence rates were taken from Gundlach KK, Maus C. Epidemiological studies on the frequency of clefts in Europe and world-wide. J Craniomaxillofac Surg. 2006 Sep;34 Suppl 2:1-2. In order to display the incidence rates visually, an average was calculated for each range, which served as the basis for the bar chart. The range is represented but not labelled on the chart for simplicity.

The incidence data are expressed as average number of birth defects per 100,000 live births. Some terminology relating to ethnic groups was modified. The “Asian” group does not include data from Japan or Mongolia.

12 ECONOMICS The conversion basis for prices quoted in the Medical Tourism Survey 2007 US$ was based on a dollar conversion rate of US$1.75 = £1 and a Euro rate of a1.2 = £1.

13 IMPACT OF ORAL DISEASES The world map on percentage of children affected by dental decay relies mainly on data of the WHO Oral Health Country/Area Profile Programme. Similar limitations to those mentioned in relation to previous data from this source apply (see 5 MAPPING DENTAL CARIES and 6 GUM DISEASES). The World Table lists the different age groups and years used. Most data are not representative for an entire country or even specific groups within a country.

The data are old: 28% is 5–9 years old, 50% is 10–19 years old, 10% is 20 years or more out of date; and only 10% is up to five years old.

15 SUGAR The map data are mainly based on statistics published by the International Sugar Organisation, a global organisation of the sugar industry, in their annual Sugar Yearbook 2008, reporting about 2007 (Source 1 as indicated in the World Table). These statistics include, for some countries, data on industrial sugar consumption as well as data for ethanol production. Sugar consumption per capita is calculated based on total sugar consumption as provided from the data source divided by the population, using the latest available population data from the United Nations Department of Economic and Social Affairs, Population Division, 2007. The resulting amount of sugar consumed per capita does not necessarily equal actual sugar intake, but proportions could also be consumed in other ways (food exports, ethanol, etc.).

Data for countries in the European Union and several other countries were not available from the Sugar Yearbook 2008; instead, data from the FAO Statistical Yearbook 2005–2006 were used (Source 2 indicated in World Table).

16 TOBACCO Data on global cigarette consumption were used from: Mackay J, Eriksen M, Shafey O. The Tobacco Atlas, 3rd

edition. American Cancer Society; 2009, courtesy of the American Cancer Society.

17 SOCIO-ECONOMIC STATUS Caries prevalence and income data in the inset are based on a paper by Hobdell & Ortiz (2009, submitted) using the WHO Oral Health Country/Area Profile Programme and World Bank GDP data from 2002.

The diagram relating Care Index and GDP (Country Income and Dental Care) is modified from: Brunton PA, Vrihoef T, Wilson NH. Restorative care and economic wealth: a global perspective. Int Dent J. 2003 Apr;53:9799. Their data are based on data from the World Health Report 1999 (GDP, adjusted for purchasing parity) for selected countries where detailed DMFT data was available from the WHO Oral Health Country/Area Profile Programme.

The diagram displaying the strength of the relationship of different oral diseases to socio-economic status (SocioEconomic Factors) is modified from: Hobdell MH, Oliveira ER, Bautista R, Myburgh NG, Lalloo R, Narendran S, Johnson NW. Oral diseases and socio-economic status (SES).

19 FLUORIDE The world map detailing the percentage of the population within countries benefiting from optimal levels of fluoride in the water is based on data provided by the British Fluoridation Society in their publication One in a million – the facts about water fluoridation, 2004. Much of the data, particularly that relating to naturally occurring fluoride in water date from before 1990. Newer data were used when available.

There is very little data on the percentage of populations within countries benefiting from fluoridated salt since this fluoride delivery system depends upon consumer choice. The availability of fluoridated salt was based on information contained in the PAHO publication Promoting Oral Health. The Use of Salt Fluoridation to Prevent Dental Caries, 2005, and on more recent data from publications and other sources.

The Borrow Foundation was kind enough to provide information on the number of children covered by their international milk fluoridation programmes.

Information on global fluoride use was based on estimations made for the year 2000 by Rugg-Gunn (2001), but was updated where more recent estimations had been made. Care should be taken in interpreting this data since populations might be benefiting simultaneously from multiple sources of fluoride. Thus, for example, the majority of those who are exposed to fluoridated water are probably also benefiting from the use of fluoride toothpaste. A simple summation of the number of people using different modes of fluoride delivery therefore cannot provide a reliable estimate of the number of people globally benefiting from fluoride.

The proportion of children reached with milk fluoridation was calculated as a percentage of the total child population. The total child population was taken from the 2009 CIA World Factbook and included people aged 0–14 years.

20 FLUORIDE TOOTHPASTE Since fluoride toothpaste is a commercial commodity, data on fluoride toothpaste sales and use are not easily available. This lack of even simple market figures is striking, considering that fluoride toothpaste is the most widespread mode of fluoride delivery worldwide. Data on the average annual expenditure per person on toothpaste were sourced from Stamm (2007). It should be noted that

105

the average annual expenditure on toothpaste is related not only to the price of toothpaste per region but also to the number of people using toothpaste and the amount used per person per year. In addition, non-fluoridated toothpastes will contribute to a limited extent to the data presented on annual expenditure on toothpastes per region.

Data on the annual cost of fluoride toothpaste in terms of the number of days of household expenditure were based on a study conducted by Goldman et al. (2008).

Annual supply was based on 182 g/person.

23 ADVOCACY AND INTEGRATION The world map indicating presence of a Chief Dental Officer or similar person dedicated to oral health within the government is based on the FDI database of World Chief Dental Officers. This collection relies on: • Self-reported data from governments • A regular questionnaire survey undertaken by the FDI’s Section of Public Health • Data provided by WHO/AFRO • Data from the Directorio odontologico del latinoamerica y del caribe (DOLAC) compiled by the Pan American Health Organzation (PAHO).

The accuracy of the information cannot be guaranteed.

24 THE DENTAL TEAM No comprehensive world statistics for dental assistants, dental hygienists, dental therapists and dental laboratory technicians exist. While two publications (Kravitz & Treasure. Survey of the dental workforce in the Commonwealth. London: Commonwealth Dental Association; 2007 and Manual of dental practice. Brussels: Council of European Dentists; 2008) give some detail about Commonwealth and European Union member states, data for the rest of the world are not easily available. Two recent papers indicate about 450,000 dental hygienists in 21 countries (Johnson PM. International profiles of dental hygiene 1987 to 2006: a 21-nation comparative study. Int Dent J. 2009;59:63-77) and 14,500 dental therapists in 54 countries (Nash DA, Friedman JW, Kardos TB et al. Dental therapists: a global perspective. Int Dent J. 2008;58:61-70.)

The numbers for dental personnel reported by the WHO World Health Statistics 2008 are not detailed enough, as they group all dental team members in the same category.

In addition, their data sources are not revealed.

25 DENTISTS The statistics about the numbers of dentists for each country come from two different sources: • Self-reported data from member associations of the FDI (2002–09; indicated as source 3 in the World Table) • The WHO World Health Statistics 2008 (indicated as source 4 in the World Table.

The WHO source gives numbers of dentistry personnel (including dental nurses, hygienists and dental laboratory technicians), rather than pure dentist numbers. Among all statistics for health professionals from the WHO World Health Statistics, only the “dentist” category uses such an undifferentiated approach, while figures for physicians, nurses and pharmacists are well separated. The reason for this difference in statistical recording is unclear.

Where possible, the highest self-reported National Dental Association member numbers from the FDI membership database between 2002 and 2009 were used in order to cover fluctuations in membership of national dental associations. However, not all dentists in a given country are mandatory members of the National Dental Association, so the numbers tend to be lower than in reality. Nevertheless, we preferred them over the numbers from the WHO World Health Statistics, since the WHO numbers grossly overrate the number of dentists by lumping all dental personnel together in this category. To highlight the problem: the figure for dentists in the USA reported by the American Dental Association is 117,822

106

(2008); the US Labour Office reports 161,000 (2006, see http://www.bls.gov/oco/ocos072.htm), while the WHO source mentions 463,663 (2000–06)! Where no data from an FDI member association were available, or the country was not a member of the FDI (2002–09), the figure from the WHO World Health Statistics 2008 was used, as indicated in the World Table.

The calculation of the dentist:population ratio used the same population figures as mentioned previously (United Nations, 2007). The ratios for countries with small numbers need to be interpreted with caution, since little differences in the number of dentists greatly affect the ratio. In addition, the world map gives an average for the respective countries and thus generalises the usually huge geographical differences within countries. The dentist: population ratios tend to be much greater in rural areas than in urban areas; as illustrated with the inset map for the African region.

The inset relating to gender ratios are taken from the WHO’s Global Health Atlas and uses information from 2000 or later (see http://www.who.int/globalatlas/docs/ HRH/HTML/Sex_occ.htm). It is interesting to note that no comprehensive data on gender distribution for the global oral health workforce exists. Total dentist numbers given in this study do not match the data about country dentist numbers given in the World Table since different years and sources were used.

26 WORKFORCE CHALLENGES The cartogram uses the total number of dentists per country (calculated as described above) and shows it as a function of the country surface on the map. One square of the map represents 1,000 dentists.

There is virtually no data on international migration of dentists, despite considerable international effort to collect data on migration of nurses or physicians. This may be due to the overall small volume of dentist migration, yet for smaller countries migration can be a significant problem. The table indicating the migration streams is based on a publication of the OECD (Dumont JC, Zurn P. Part III: Immigrant health workers in OECD countries in the broader context of highly skilled migration. International Migration Outlook SOPEMI 2007 Edition. Paris: OECD; 2007). Their estimations, however, are based on data from 1999–2000. It is thus justified to say that the map presented is only a snapshot of a situation about 10 years ago – yet no more recent data could be identified. The migration data have been simplified and condensed; only the major migration streams of 100+ dentist, source countries and destination countries are represented on the map.

27 DENTAL EDUCATION The statistics of dental schools worldwide are based on a number of sources, mainly the FDI World Directory of Dental Schools, last updated in 2006; the FDI Basic Country Facts from 2004, a collection of self-reported data from FDI member associations; and the Directorio odontologico del latinoamerica y del caribe (DOLAC) from the Pan American Health Organization (PAHO). Additional sources, as indicated in the World Table, complement this data.

For most countries, the number of dental schools has remained stable over the last 10 years, particularly in highincome countries. In specific countries, such as Brazil, India, Pakistan and others, the number of dental education institutions has increased significantly, mainly due to a boom in private dental schools.

29 FDI WORLD DENTAL FEDERATION The map of FDI member countries uses the latest available data from April 2009.

Community Periodontal Index of Treatment Needs (CPITN) – a complex assessment index used to establish periodontal treatment priorities for individuals or population groups. composite filling – tooth-coloured filling made of resin. country income classifications – economic classification of the World Bank based on Gross National Income (GNI) per capita, expressed in US dollars. In 2007, low income was classified as $935 or less; middle income as $936 – $11,455; and high income as $11,456 or more. cross-infection control – all hygiene and protective measures taken to avoid transmission of a communicable disease from one person to another during dental treatment. crown – restoration that is placed over a tooth and is used to rebuild decayed or broken teeth or to improve the cosmetic appearance of a tooth; also known as a cap. dentine – the mineralised substance that makes up most of the tooth structure. It is covered at the crown by enamel, at the root by cementum and protects the sensitive inner pulp. dentition – (1) the process of tooth eruption; (2) the entire set of teeth present in a person’s mouth. fluorosis – condition of the tooth enamel resulting from excessive fluoride exposure. Mild and moderate fluorosis can hardly be detected; only the rare severe forms are characterised by visible mottling. dental plaque – the biofilm the develops on the surface of teeth, made up of bacteria. dento-alveolar trauma – injury or damage to teeth or supporting bone structure, usually caused by excessive force from outside. dentures – partial or complete set of artificial teeth for the upper and/or lower jaw.

DMFT – index used to measure the decayed, missing and filled teeth of individuals or population groups in epidemiological surveys.

Early Childhood Caries (ECC) – The American Academy of Paediatric Dentistry defines ECC as “the presence of one or more decayed, missing or filled tooth surface in a child 71 months or younger”. edentulism – the absence or complete loss of all natural teeth. epidemiology – the science of the causes, distribution, and control of disease in populations.

Primary Health Care – Primary Health Care, as defined by the World Health Organization in 1978 is “essential health care, based on practical, scientifically sound, and socially acceptable methods and technology, universally accessible to all in the community through their full participation, at an affordable cost, and geared toward self-reliance and self-determination”. public health – science concerned with the health of communities and populations.

fillings – restorations made of amalgam, resin (composite), metal, ceramics or other material, used to replace lost tooth tissue.

root-canal treatment – procedure to remove diseased or damaged pulp tissue from inside a tooth and seal it with special filling material.

fissure sealant – resin material that is placed in the pits and fissures of teeth in order to prevent the development of dental decay.

squamous cell carcinoma – a cancer developing from epithelial cells. It is the most common form of oral cancer.

fluoride – mineral that helps prevent tooth decay if used in recommended dosage.

Streptococcus mutans – common bacteria found in dental plaque and mainly responsible for dental decay.

gingivitis – inflammation of the gum; clinical signs may include swelling, bleeding upon probing or brushing, and/or pain.

Gross Domestic Product (GDP) – total market value of all the goods and services produced within a country during a specified period. halitosis – medical term for bad breath. It can result from a number of factors such as poor oral hygiene, decayed teeth and gum disease, but also from general health problems. orthodontics – the branch of dentistry concerned with the development and treatment of malformations of teeth, jaws and facial structures. periodontal diseases (periodontitis) – group of diseases affecting the tissues that support and anchor the teeth.

temporomandibular joint disorder (TMJ) – term summarising a group of symptoms involving the joint and muscles between lower and upper jaw.

Symptoms include headaches, soreness in the chewing muscles, and clicking or stiffness of the joints. wisdom teeth – the teeth at the back of the dental arch. They are the last teeth to erupt, typically in early adulthood. Due to lack of space they are often impacted (stuck) and need to be removed surgically. xerostomia (dry mouth) – the condition of not having enough saliva to keep the mouth wet.

It can cause difficulties in tasting, chewing, swallowing, and speaking, and is often associated with increased levels of tooth decay.

periodontium – the tissues surrounding a tooth and anchoring it in the supporting bone.
