(Figure 1B) This results in heating of areas which are directly targeted by the electrode-pins to temperatures leading to ablation and resurfacing of the skin directly in contact with and below the array, leaving intact or slightly affected zones in between the targeted areas. In the short term, the preserved tissue helps to maintain skin integrity. In the long term, it serves as a pool of cells that promote wound healing.

FACIAL PIGMENTATION
Face is the key to fortune as the old saying goes. The saying becomes further more relevant in the present day times as possessing attractive external persona and cosmetic appeal have become essential for professional and personal success . A tiny facial blemish or an innocuous spot , scar or imperfection can shatter self esteem or erode the confidence of an individual thus resulting in poor quality of life. Nature has blessed Asian skin with color which protects us from the harmful effects of UV light and helps in vitamin Dsynthesis . Skin Color is contributed by – melanin, hemoglobin and carotenoids , former being the most important determinant of skin color. All races have equal number of color producing cells known as melanocytes irrespective of their skin color, however it is the size and arrangement of these tiny sacs which carry the melanin pigment in them (melanosomes) that determines the final color of skin. Caucasians or white races have smaller melanosomes which lie in one place in contrast to the darker races which have larger melanosomes that lie scattered throughout the pigment cell .

Once the technique for integrating varying shades and composite types to construct a single laminate has been mastered and the anatomical landmarks of a smile understood, the placement of laminate veneers becomes a series of sequential steps, each one following the other to successful completion. > A successful clinical outcome depends upon achieving healthy gingival tissues prior to any aesthetic procedure. > Remove any unsatisfactory restorations and prepare retentive slots in existing indirect restorations.
WHITENING VS. BETTER ENAMEL CARE (ACP WHITENING) – ‘WANT’ OR ‘NEED’ BASED DENTISTRY?

Do we really have a definition for ‘want’ based and ‘need’ based Dentistry? What we do have is a broad perspective of ‘want’- based and ‘need’- based dentistry. Simply, ‘want based’ would be that which the patient asks for and is not a critical need of the hour. ‘Need based’ dentistry would be that which is the
need of the hour or when treatment is given when the patient is in difficulty or in pain. Most of our practices are devoted to ‘need based’ dentistry merely because that is the bulk of the patients we get People do not want to come to the dentist unless they have a problem to address. We are a little different from the western world. They have patients that come into a dentist’s office with requests that are not need based. That’s probably because they come in for hygiene appointments, are comfortable with the clinic and then are very aware and comfortable seeking additional work done to enhance their smiles. Western Dental offices also are much more aggressive in offering treatments with special offers than Indian offices are. Since we do not have typical hygiene departments in our dental offices we tend to miss out on entire section of society till the need arises.

thought is to the word that the feeling is to the facial expression. He pointed out in 1806 that a smile could convey a thousand different meanings, yet it is the most easily recognized expression. And because the mouth is one of the focal points of the face , it should come as no surprise that the smile plays a major role in how we perceive ourselves, as well as in the impressions we make on the people around us. A charming smile can open doors and knock down barriers that stand between you and a fuller, richer life. An attractive or pleasing smile clearly enhances the acceptance of the individual in the society where he belongs and the character of the smile influences to the great extent the attractiveness and the personality of the individual.
PRINCIPLES OF CREATING A SMILE
In our modern competitive society, a pleasing appearance often means the difference between success and failure in both our personal and professional lives. Scottish physiologist Charles bell (1774-1842) was quoted as remarking that the

A CASE REPORT OF USING THE BIODEGRADABLE FIXATION DEVICE (ENDOTINE) FOR DOUBLE CHIN WITH ORTHO-GNATHIC SURGERY Dong-Ju Choi, Se-Heung Choi, Byeong-Gi Park, Sang-Sik Chae1, Tae-Sun Lee1, Jun-Woo Park Department of Oral and Maxillofacial Surgery, Kangdong Sacred Heart Hospital, Hallym University, Seoul, Korea Department of Oral and Maxillofacial Implantology, Graduate School of Clinical Dentistry, Hallym University, ChunCheon, Korea1
IntroductIon Recently, Orthognathic surgery has developed technically with a lot of attention and played a leading role in solving dentofacial anomalies. But, for the purpose of improving aesthetic as well as functional aspects, the patient treated with orthognathic surgery has some complaints about lack of the amount of improvement in nasal and neck area after surgery. It is possible to solve in skeletal problems during surgery, while still unpredictable in soft tissue asymmetry after surgery1. In order to improve these soft tissue asymmetry, the orthognathic surgery need more additional aesthetic surgeries like - chin surgery (chin augmentation, chin reduction), rhinoplasty, facial contouring surgery, and submadibular soft tissue surgery. Above all, especially loose condition below the chin, in other words – Double chin, is generated by locally accumulation of fat through stretching of thin muscle in the neck area. This is the main factor causing the patient’s dissatisfaction, but the suitable surgery is not developed still now. In case of excessive soft tissue below the chin area, local resection or liposuction are widely used for treatment. But, it is impossible to remove all fat tissue completely and if the body weight is increased, the new fat is likely to be concentrated in the region of liposuction area by accumulation of additional fat in residual original fat tissue.2 Traditionally, the 2-stage surgery which means soft tissue repositioning surgery after maxillofacial surgery

ABSTRACT Orthognathic surgery has been accepted by professions as a useful method to obtain remarkable result in oral and maxillofacial deformities. Now, in development of this method with additional aesthetic surgery, above of them, the soft tissue lifting with absorbable Endotine device is considered as a very excellent method. We reported the case which showed a good result to improve double chin with two jaw surgery and Endotine esthetic surgery simultaneously Key Words – orthognathic surgery, double chin, Endotine.
is preferred, because the change of hard and soft tissue after facial asymmetry surgery has been known as no significant relevance in vertical change and this surgery is more predictable.3 The prognosis of 2-stage surgery is more predictable, but duration of treatment is so long and the patient’s discomfort is increased by more surgical procedures. In recent years, several methods to improve soft tissue incongruity with orthogranthic surgery have been introduced to decrease the patient’s discomfort. Among these many methods, ENDOTINE Ribbon(Coapt System Inc., United state) has been proven its reliability and ease, so it is widely used in forehead or mid-face lifting.4,5,6 However, it is not yet widely used to treat double chin and a few discussion about this method applicated to orthognathic surgery has been performed.
Jan-Mar 2015 In this case, the reflected prominent double chin was treated with using a two-jaw surgery and Endotine Ribbon for double chin lifting at the same time. The operation procedure was simple and the result was so effective. So we report this case, becasue aesthetic improvement is good and excellent and patient’s satisfaction is also high.
case report 1. Patient information A 29-year-old female patient visited the Department of Oral and Maxillofacial Surgery, Kangdong Sacred Heart hospital, Hallym University complaining of asymmetry and malocclusion for orthognathic surgery in November 2012. The patient was referred our clinic after orthodontic treatment in private dental clinic for orthognathic surgery. She was single and had high expectation for aesthetic part and she wanted to improve mid-face depression, long face, double chin and malocclusion. 2. Clinical and radiological examination As the result of clinical examination, difference of the canting of maxillary posterior area was not big with just
FACIAL PLASTIC SURGERY 1mm, and asymmetry of the maxilla was not severe. Nasolabial angoe was more than 90 degrees and mild depression was shown in mid-face area. Maxillary anterior teeth was exposed about 5mm in relaxed state, and freeway space was about 4mm. Nose tip was slightly bent to right side, and both upper and lower lip and chin point was shifted to left side about 2mm. Upper and lower central incisors were shifted to left side about 1mm from midline. The occlusion relationship was shown as class I tendency. (fig 1) In radiographs, the maxillar was mild retrognathism and vertically long tendency compared to whole facial aspect. The mandible was shown as a little protrusion and the both angle were more developed. Chin area was longer than the average. Overall, the mandible was shown asymmetry to be shifted left side. (fig 2) The treatment purpose of this patient was improvement of openbite by malocclusion in functional aspect and long face in aesthetic aspect. These problems were planned to treat by Le Fort I osteotomy of the maxilla and mandible BSSRO, angle reduction, and genioplasty. But it was expected to be more severe her double chin after orthognathic surgery, so chin lifting with Endotine Ribbon

area was to backward movement about 2mm and upward about 4mm, so lower part of face was more shorted than before surgery. Also the angle reduction was performed. After orthognathic surgery, the incision was performed in behind of the both ears by rhytidectomy approach and the soft tissue of double chin area was lifted by Endotine Ribbon. The operation time took an additional 30 minutes

and the patient did not appeal any special discomfort with lifted chin area. The precautions of not to greatly extend the neck and excessively shake her head were kept in mind and she was shown to relatively rapid recovery. Immediately after surgery, the effect of lifting did not be recognized prominent and she had concern about being touched Endotine Ribbon device under the skin. But, it was not care much more because it was absorbable material. 4

FACIAL PLASTIC SURGERY dIscussIon The various methods are used to solve disharmony of facial soft tissue. Many procedures like liposuction surgery, botulinum toxin injection, and facial lifting with absorbable material are perfomed for this problem, but above all, the facial lifting with absorbable Endotine are more used to advantage in more simple and predictable result.7,8 Endotine device is anatomically fixed to the structure site called SMAS - Superficial Muscular Aponeurotic System. In 1976, Mitz V. defined at first the SMAS layer as structure divided into between superficial and deep adipose tissue in parotid and cheek region.9 After the study, the phenomenon of sagging the facial skin is just for skin and SMAS structure connected with skin is known as important structure with sagging. SMAS has been recognized as an essential structure in facial lifting. It is located under the skin of the face as a single layer structure composed of a continuous, constant and close to spread over the entire face. SMAS and skin are connected with strong fiber septum(fibrous septa) and moved together when the muscle acts. Therefore, the skin and SMAS should be pulled strongly upward and fixed with periosteum or deep tissues, so it can be maintained for a long time and not recurred. In 2007, Ryan N. researched about Endotine midface st 4.5 device for 121 patients in mid-face lifting and it was known as simple, effective, and easy to learn technique. Among them, 78 patients were treated with rhytidectomy or blepharoplasty and it was revealed to more prominent result.10 In addition, Anthony P in 2007 reported many cases of eyelid cosmetic rhinoplasty with mid-face lifting using endotine fixation.11 In 2007, Allison M. reported adventages of Endotine about no require a metal screw, no need for suture, and no remove the device after healing. However, possible complications are expected about exposure of device, need for repositioning by asymmetry after surgery, or tenderness of device under the very thin skin. Additional expensive costs are also considered.12 On the other hand, concerns about side effects are going to be bigger, while a lot of interest is with facial lifting. In 2006, Jennifer L reported some side effects like alopecia on brow fixation, loss of elevation, implant palpability, and paresthesia. And he measured the thickness of the 14 skulls for more safe facial lifting procedure.13 In orthognathic surgery area, Choi JY etc in 2010 reported that the procedure of Endotine Ribbon with orthognathic surgery in 10 patients were shown good results about solving lip cant or disharmony of gonial angle area.14 In this case, the chin lifting was applied to the patient who was expected more severe double chin symphtom after orthognathic surgery and the result is so successful. In general, the tongue and hyoid bone is more downward to

Jan-Mar 2015 keep the airway physiologically when the mandible moves to backward.15 This makes more obtuse angle of between neck and chin. So, movement of the mandible to backward makes the form of chin and neck anesthetic in double chin patients. In this respect, more good results can be obtained in well-selected patients in procedure with orthognathic surgery. The patient should be felt some discomfort because the excessive extension and rotation of neck were avoided to fixed entotine device with periosteum and skin layer. Also, the tenderness of device under the thin skin seems inevitable shortcoming. The manufacture describes the device would be absorbed completely in 12 months through hydrolysis. So its safety is somewhat verified. But the more studies are needed about fixation periods by loss of strength of the material itself, integrity and force to downward because of its complete absorbable characteristics.
conclusIon To date, the facial lifting technique was reported successful for solving the soft tissue disharmony in maxillofacial region. But it is not yet being so many operations with orthognathic surgery at the same time which is shown most noticeable improvement. This is thought to be result of factors that uncertain prognosis and longer operation time are contemplated when the hard and soft tissue surgery are done at the same time. However, if more certain anticipated indication was taken through accurate diagnosis and analysis of facial soft tissue, the Endotine Ribbon procedure with orthognathic surgery would be a great effective method.

NOVEL MINIMALLY INVASIVE FRACTIONAL MICRONEEDLE RADIOFREQUENCY DEVICE AND APPLICATIONS IN COSMETIC DERMATOLOGY Avitus John Raakesh Prasad, Sheeba Grace, Vijay Kumar J.
IntroductIon The field of cosmetic dermatology in the treatment of tissue tightening and scar remodelling has developed very rapidly over the past several years, with many new devices appearing on the market that utilize radiofrequency (RF) energy to effectively tighten and rejuvenate the skin.1,2 What originally began with a single monopolar RF device has progressed into a world in which there are skin-tightening devices that utilize, besides monopolar RF energy, bipolar energy and tripolar energy, and newer machines that boast five and eight poles of RF energy. Microneedle / Fractional RF is a newer technology used for skin rejuvenation, tightening, body sculpting, and scar remodeling. These technologies provide an alternative to ablative lasers, and are said to reduce the incidence of side effects and increase patient compliance. Microneedle / Fractional RF induce dermal neocollagenesis causing minimal or no epidermal disruption, thereby limiting adverse effects and very minimal down-time of few hours to 2-3 days.
MechanIsM of actIon of radIofrequency based devIces
ABSTRACT Skin resurfacing has evolved rapidly over the past 15 years from ablative techniques to nonablative methods and most recently fractional ablative resurfacing. This article helps in understanding this new technology and its uses. This Nonlaser systems based on RF technology is used for skin rejuvenation, tightening, body sculpting, and scar remodelling. Device: Fractional / Microneedle RF is gaining popularity as an alternative to fractional and non ablative lasers in terms of efficacy, outcome and minimal downtime. Indications: This newer technology can be used for several indications such as skin tightening, periorbital tissue tightening, treatment of nasolabial lines and jowl, scar revision and remodelling, treatment of photodamaged skin and primary axillary hyperhidrosis. Facility: Microneedle RF can be carried out in a clinic or hospital setting or a nursing home with a small operation theatre. Informed consent and counseling: The dermatologic consultation should include detailed assessment of the patient’s skin condition and skin type. An informed consent is mandatory to protect the rights of the patient as well as the practitioner. All patients must have carefully taken preoperative and postoperative pictures. Parameters: Depends on the indication, the area to be treated, the acceptable downtime for the desired correction, and to an extent the skin color. Anesthesia: There is acceptable pain and is tolerated well by patients but may require topical anesthesia. In most cases, topical cooling and numbing using icepacks is sufficient, even in an apprehensive patient. Postoperative care: The newer radiofrequency systems are safe, even in type V & VI skin types, and postoperative care is minimal. Proper postoperative care is important in avoiding complications. Post-treatment edema and redness settle in a few hours. Postoperative sun avoidance and use of sunscreen is mandatory. Use of Epidermal growth factor gel helps in faster healing and recovery time.

DERMATOLOGY inherent resistance (impedance) converts the electrical current to thermal energy. This reaction is dictated by the following formula: energy (J) = I 2 x R x T (where I = current, R = tissue impedance, and T = time of application). (3) High-impedance tissues, such as subcutaneous fat, generate greater heat and account for the deeper thermal effects of RF devices. Radiofrequency energy can be transferred from an electric field to charged particles in the target tissue via 3 mechanisms: the orientation of electric dipoles that already exist in the atoms and molecules in the tissue, polarization of atoms and molecules to produce dipole moments, or displacement of conduction electrons and ions in the tissue. In all 3 mechanisms, heat is generated by the movement of particles in response to an electric field respectively by the collisions between the transmission charges and immobile particles.4 Various considerations are required for there to be successful transfer of the RF energy into thermal energy, including the size and depth of the tissue being treated, as one needs to consider the tissue impedance of the skin being treated. Since RF energy produces an electrical current instead of a light source, tissue damage can be minimized, and epidermal melanin is not damaged either. Using this theory, RF energies can be used for patients of all skin types since does not act on any chromophores mainly melanin and allows for different depths of penetration based on what is to be treated, allowing for ultimate collagen contraction and production of new collagen.5
evolutIon of radIofrequency devIces The first device in this technology was a monopolar radiofrequency (RF) device that was US FDA approval for noninvasive treatment of the periorbital rhytids in 2002, and for the full face in 2004 using this proven mechanism of skin tightening.6,7 Disadvantages of that 1st generation device included inconsistency of clinical results and significant discomfort during treatment. Newer bipolar and multipolar RF devices are constantly being developed to improve results and minimize discomfort. Monopolar systems deliver current through a single contact point with an accompanying grounding pad kept at a different location in contact with the body that serves as a low resistance path for current flow to complete the electrical circuit.3 Monopolar electrodes concentrate most of their energy near the point of contact, and energy rapidly diminishes as the current flows toward the grounding

Jan-Mar 2015 electrode.7 Bipolar devices pass electrical current only between two adjacently positioned electrodes applied to the skin. No grounding pad is necessary with these systems because no current flows throughout body to complete the circuit.8 The tripolar / multipolar RF systems exclusively utilize the effects of combining unipolar RF and bipolar RF energies in one applicator to simultaneously heat deep and superficial tissue layers, while protecting the surface skin.7 The tripolar RF technology uses sophisticated algorithms to control the treatment electrodes which change the current and polarity to achieve variable energy focus in different fat layers resulting in visible clinical results. This system is also used for the treatment of skin laxity and facial recontouring. Newer devices have been introduced, like the Viora Reaction™ (Viora, NJ, USA) which also utilizes three poles of RF energies, but is distinguished from the other devices in that it emits its RF energies at different RF frequencies which is unique to this machine. Clinical trials with this device have not been published except individual case reports. Another new device, the Venus Freeze™ (Venus Concepts, AZ, USA) uses eight poles of RF energy and pulsed magnetic fields to have its effect on skin rejuvenation and body contouring. Clinical published studies with this device are also not yet available. This article will focus on the Fractional Microneedle RF (FMRF) which is a very new technology which has been developed and upgraded in the last 2 years.
What Is sublatIve (superfIcIal) fractIonal rf Fractional RF was developed to address the shortcomings of ablative and non-ablative device modalities performing ablation on small microscopic “ dots ” of skin allowing rapid healing with minimal pain and downtime.9,10 In Sublative Rejuvenation™ the treatment is delivered via a hand-held applicator that is fitted with a square disposable tip at its distal end. The tip consists of parallel rows of bipolar arranged electrode-pins, forming an array of positively and negatively charged electrodes for multiple delivery of 1 MHz of RF energy. ( Figure 1A) Energy up to 20 J can be delivered at a 5% or 10% coverage rate via 64 or 144 (according to the specific tip) equally spaced electrode-pins, each approximately 200 µm in diameter. Radiofrequency delivery via dry skin flows between each pair of positively and negatively

charged electrode-pins such that part of the electrodepinhead array forms a closed circuit of bipolar RF current that passes into the epidermis and deeper into the dermis. (Figure 1B) This results in heating of areas which are directly targeted by the electrode-pins to temperatures leading to ablation and resurfacing of the skin directly in contact with and below the array, leaving intact or slightly affected zones in between the targeted areas. In the short term, the preserved tissue helps to maintain skin integrity. In the long term, it serves as a pool of cells that promote wound healing.
The tips can be monofractional to bifractional tips in newer machines. Bifractional tips passes deeper RF energy and effective for deeper dermal remodelling. Monofractional is mainly used for superficial dermal remodelling. The distance between the electrodes is directly proportional to the energy delivered and depth of penetration. If deeper work is needed lesser number of pins is used to prevent collateral damage in epidermis when higher energy is used.

(Figure 3B) Ablative technology commonly forms a conical or columnar injury zone. The term “sublative” is a derivative of “sub-ablative,” referring to the ability to generate heat energy well beneath the ablated zone below the epidermal surface and where the effect is largely caused by a large volume of heated tissue.

which are inserted into the skin to desired depth and RF current is passed. In microneedle RF the treatment is delivered through probe tip which consists of an array of microneedles over a minimum area of 10 mm2 that form an array of positively and negatively charged electrodes. The microneedles delivered bipolar radiofrequency energy in a fractional manner that can be inserted into the skin at a depth of 0.5 to 3.5 mm depending on level of treatment in the dermis.
DERMATOLOGY The microneedles array can consists of needles as low as 25 needles per tip to 81 needles per tip. Some tips have higher number of needles for superficial dermal remodelling. The microneedles can be insulated except the tip or noninsulated. Non-insulated microneedles causes epidermal thermal injury which can produce epidermal resurfacing while insulted microneedles work in the dermal zone causing profound dermal remodelling. The microneedles can also be blunt which will work as the same mechanism as Sublative RF working through the epidermis into deeper part of dermis. The sharp microneedles in contrast deliver the RF energy directly to the desired zone of the dermis creating better treatment outcome. (Figure 5B)
Figure 4A. In the microneedle tip, the length of needles can be adjusted to pass RF energy through epidermis in a fractional array into the desired depth in dermis.

paraMeters Parameters have individual variations depending on different equipment since each company has a different interface. Few basic parameters which are common to most of the Microneedle RF equipment are discussed below.

More the distance between the needles, longer needles can be used and deeper the needles can be passed into the dermis with higher RF energy delivery. Different needles lengths are available are separate tips. Newer tips have manual and motorised adjustment of length of needles, this is very useful since the same tip can be used to deliver RF energy to different levels in the dermis. The RF energy

contInuous or pulsed Wave Continuous wave means when the RF energy is passed, it continuously delivers the energy till the foot switch or ON button is pressed. There is no ON or OFF time associated with it. Pulsed wave has an oscillating wave when the ON button or foot switch is pressed and it has an ON and OFF time. (Figure 7) When a continuous wave is used there is no cooling phase since there is no ON and OFF time which can be painful for the patients. The pulsed mode can be single or repeat. Single mode means only one wave of pulse is passed when the foot switch is pressed. Repeat mode means multiple waves of the pulse are delivered till the foot switch is ON.

The ON and OFF time is set in seconds and it is used only when the pulsed wave mode is selected. Ideally as low as 0.5 seconds to 3 seconds is kept as ON time. The OFF time is the time given for the cooling of the treated area before the next wave passes, it reduces the discomfort to the patient.

The OFF time can be equal to ON time or more than ON time, it all depends on the patients comfort.
energy The energy is in watts or joules. Its set to a value depending on the depth of penetration and also the amount of heat needed to be delivered to the dermis. The energy E in joules (J) is equal to the power P in watts (W), times the time period t in seconds (s): E(J) = P(W) × t(s), joules = watts × seconds (J = W × s). Example : What is the energy in joules when a power or 10 watts is used for time duration of 2 seconds? Using the formula it can be derived as E(J) = 10W × 2s = 20J. An Energy joules of 10 – 40J can be used depending on the condition and location of treatment area.
The needle depth is available as preset needle length ranging from 0.5mm to 3.5mm. Newer machines have adjustable needle length. The benefit is that in preset needles if energy has to be delivered at different depth in same treatment session then different needle sizes have to be used but in newer adjustable needles, the same needle can be adjusted by increasing /decreasing the needle length thereby being cost efficient and time saving.
Manual vs autoMated needle InsertIon Manual insertion of needles is done by the user but it can lead to difference in depth penetration. But in newer automated needle insertion, the handpiece pushes the needle to the same depth every time it inserts giving precision to the treatment. Passes Passes means treating the area again after few minutes of completing the first pass treatment. The number of passes can be from 2 to 4 passes depending on the area being treated. Near the eye and forehead will need one to two passes, the cheek and chin two to four passes and for the neck two passes is sufficient.

Thus, for effective resurfacing to occur, regeneration of the epidermis as well as portions of the dermis is required, thereby improving both the appearance and health of the aged skin.29

UNDERSTANDING OF STEVENSJOHNSONS SYNDROME AND ITS MANAGEMENT:-REVIEW ARTICLE Dr. Rabiya A Hameed
INTRODUCTION First described in 1922, as an immune-complex–mediated hypersensitivity reaction that is a severe expression of erythema multiforme. Stevens - Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are variants of a same disease arbitrarily separated by percentage of body surface area involvement in both conditions. It is characterised by erythematous macules leads to epidermal detachment and mucous membrane erosions. SJS typically involves the Skin and mucous membrane; sometimes in its minor presentation it involves mouth, nose, eye, respiratory tract and GI. It is important to diagnose Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) and manage them properly because chances of missing are more. SJS is a serious systemic disorder with the potential for severe morbidity and even death. The mortality rate of SJS and TEN is high: even in moderately severe cases. Complications are seen in patients who survived from this too. Several classifications has been recommended to distinguish between SJS and TEN, the simplest is as follows. »» Less than 10% of body surface area involved – SJS »» 10-30% of body surface area involved – SJS/TEN (Overlapping Type) »» More than 30% of body surface area involved - TEN

ABSTRACT Non-steroidal anti-inflammatory drugs are commonly prescribed in dental practice after minor oral surgical procedures, root canal treatments, periodontal surgeries etc. Dentists prescribing these medications must know about possible side effects and warn their patients. One such potential complication of commonly used drugs, like NSAID’s, is Stevens-Johnson syndrome, a potentially fatal condition that manifests mainly on the skin and mucosal surfaces but also affects other vital organs. Stevens-Johnson syndrome otherwise known as erythema multiforme. Stevens-Johnson Syndrome(SJS) and Toxic Epidermal Necrolysis (TEN) are variants of a spectrum of conditions characterised by erythematous macules evolving to epidermal detachment and mucous membrane erosions. In SJS there is less than 10% body surface area involvement; where as in TEN more than 30% and 10-30% overlaps cases. The mortality rate of disease is high that’s why it is important to be able to recognise disease early and manage them properly. In this article the clinical features of this condition and multidisciplinary management of the patient are described in brief.
Jan-Mar 2015 PATHOPHSIOLOGY SJS/TEN is an immune-complex mediated hypersensitive disorder that caused by multiple drugs and body’s response to its metabolites. An inability to detoxify the drug and its metabolites, serves as heptans, which complexes with host epithelial tissues there by initiating immune response. Initiated immune triggers various mediators such as Fas, Ligand and tumour necrosis factor (TNF), leading to apoptosis of keratinocytes.
dermotology involvement, sometimes leads to corneal ulceration, anterior and uveitis. It does not limit to Skin and mucous membrane, it spreads to involve Pulmonary and digestive and renal system. Gastrointestinal tract involvement will result in diarrhoea, malena and oesophageal necrosis. Renal involvement will result in proteinuria, haematuria and azotaemia. Pulmonary involvement shows shortness of breath, hypoxia and haemoptysis. The course of the disease is unpredictable and is depend upon various factors. Sepsis is the most important cause of mortality. Extensive erosions put patients at risk of infection will result in pulmonary complications and multi-organ failure.
MANAGEMENT OF SJS/TEN SJS and TEN are life threatening conditions that need early diagnosis and extremely intensive care with experienced multidisciplinary team work. Withdrawal of all potential causative agents is essential for a favourable outcome. Morbidity and mortality increase if the causative agent is withdrawn late. It is been observed that death rates were lower in cases where the half life of causative agent is less and withdrawal is less than 24 hour.
GENERAL MANAGEMENT (CHART - 1) RECOGNISING SJS AND TEN It is easy to recognise SJS/TEN early if signs and symptoms are familiar to us, especially the initial ones (Prodromal Signs) such as Fever, malaise, cough, stinging eyes and sore throat. Later patient develops skin eruptions that start as an erythematous lesion followed by maculae. Initially these lesions are discrete maculae, later ruptures and coalesce with each other. The rash first appears on the face and upper part of the trunk and proximal part of the extremities and spread rapidly to the rest of the body. Nikolsky sign (separation of epidermis from dermis with lateral pressure) can be demonstrated. It is an important sign but not pathognomonic sign of this disease. Finally the apoptotic epidermis comes off leaving large areas of red exudative dermis exposed. The skin and mucosal lesions are painful. Mucosal involvement in SJS/TEN usually starts as Erythema, followed by painful erosions on the buccal, ocular and genital mucosa and usually it involves more than one site. In Large no of patients, conjunctival

DISCUSSION Numerous studies have shown that up to 10% of the total number of hospital admissions are because of adverse drug reaction. Fortunately, only about 2% of adverse cutaneous reactions are severe and very few are fatal such as SJS/ TEN. SJS is a severe adverse drug reaction characterized by widespread lesions affecting the mouth, eyes, pharynx, larynx, esophagus, skin and genitals. It almost invariably involves the oral mucosa. The spectrum of severe cutaneous adverse drug reactions includes SJS or TEN; All cases of SJS and TEN should be confirmed by biopsy. In Biopsy initial lesion shows suprabasal layer apoptotic keratinocytes. Later lesion shows full-thickness epidermal necrosis and separation of epidermis from dermis. As numbers of conditions are similar to these diseases so it is important to rule out the SJS/TEN from them by histopathological study (Table-1). SJS and TEN can be easily confused with erythema multiforme. In 1993, a group of experts proposed a new classification in which SJS was separated from the EM spectrum and added to TEN and created a new spectrum of severe drug related disease. The lesions in our patient had an atypical appearance and epithelial detachment exceeding 10% BSA.

FACIAL PIGMENTATION Vibhu Mendiratta
Face is the key to fortune as the old saying goes. The saying becomes further more relevant in the present day times as possessing attractive external persona and cosmetic appeal have become essential for professional and personal success . A tiny facial blemish or an innocuous spot , scar or imperfection can shatter self esteem or erode the confidence of an individual thus resulting in poor quality of life.
Pigmentation is quite common in Indians and often turns out to be a complex diagnostic problem. Genetic and racial factors are important.
Nature has blessed Asian skin with color which protects us from the harmful effects of UV light and helps in vitamin D synthesis . Skin Color is contributed by – melanin, hemoglobin and carotenoids , former being the most important determinant of skin color. All races have equal number of color producing cells known as melanocytes irrespective of their skin color, however it is the size and arrangement of these tiny sacs which carry the melanin pigment in them (melanosomes) that determines the final color of skin. Caucasians or white races have smaller melanosomes which lie in one place in contrast to the darker races which have larger melanosomes that lie scattered throughout the pigment cell . The “pigment factory “ or the melanocytes lie in the superficial layer of skin called the epidermis . The production of melanin depends on several external and internal factors. The melanocytes can be easily stimulated to produce more melanin by ultraviolet rays in the sun light, frictional force on skin, chemical injury , hormonal changes during pregnancy , drugs , autoimmune diseases such as thyroid etc.
1. Congenital- Refers to conditions that are usually present at birth or appear in the first few years of life. Some of them are familial namely melanocytic naevi or the pigmented moles while others are isolated abnormalities. Pigmentation can only be limited to skin or it may be associated with abnormalities in brain, eyes, ears , teeth and the musculoskeletal systems . Pigmented moles, cafe- au-lait macules, lentigines are some common spotty pigmentary problems which may involve the face.
Facial hyperpigmentation implies pigmentation or darkening of skin involving predominantly the face and the neck .

Facethetics | Issue 3 Vol. 1
causes of facIal pIgMentatIon can be broadly classIfIed Into
2. Acquired – Comprises of conditions that appear later on in life . The cause may be genetic but is external in most of the cases. Pigmentation may be progressive, may show gradual darkening and spread to other areas , may have associated symptoms like photosensitivity , itching , burning etc. Establishing the cause in acquired pigmentation requires a detailed personal history and some lab tests . Melasma, toxic melanosis, pigmented cosmetic dermatitis and post inflammatory and drug induced pigmentation are some common conditions in the Indian scenario.
Jan-Mar 2015 congenItal Naevus of ota-It is a congenitally acquired speckled grayish - blue pigmentation, predominantly involving sclera, conjunctiva, forehead, scalp, alae nasi and ears. The distribution is mainly restricted to distribution of trigeminal nerve. This disorder is most common in Asian people.It is usually not visible at birth, but become progressively darker in childhood and persist in adult life. Café- au lait macules ( CALMS)- Are flat, brownish macules which are well marginated and the size may vary from .5mm to > 1.5 mm. Number can be variable ( one – many) . More than 6 CALMS > 1.5 mm are indicative of Neurofibromatosis. Conginatal melanocytic naevus- Are brownish to grayish –blue patches, plaques or papules . They may be small in size or as large as 20 cm. Some of these show excessive localized hair growth ( hypertrichosis) . These moles show increased skin rugosity with time, darkening of color and giant naevi may also develop melanoma.
acuIred condItIons a. PATCHY PIGMENTATION / SPOTS EPHILEDS/FRECKELS- It is a light colored , poorly defined , pale brown, macular lesion, usually less than 3mm in diameter which appears on sun exposed sites such as face, arms and hands during period of UV exposure.It is commonly seen in individuals who have red or light colored skin and hair. Freckles concentrate over the centrofacial area and tend to fade or become lighter in winter months. LENTIGINES- These are also hyperpigmented macular skin lesions which occur over both exposed and the sun protected areas namely face, extremities, trunk and mucosae. Lentigines persist throughout the year and do not fade away as. there is an increased proliferation of melanocytes in response to sun exposure in faired skinned people. Lentiginosis may be seen in some inherited genetic syndromes like Peutz- Jegher’s syndrome, Cronkhite- Canada syndrome where lentiginosis is seen in association with intestinal polyps. b. DIFFUSE PIGMENTATION MELASMA- It is also known as mask of pregnancy. It is a multifactorial disorder and can be seen in anemia, thyroid gland dysfunction, after anticonvulsant and oral contraceptive therapy. This common acquired facial hypermelanosis is seen in both men and women but is more common in the latter. It occurs mainly in sun exposed facial skin , occasionally affecting the forearms. Many cases are attributed to pregnancy. It is not uncommon at any time during the years of reproductive activity and has been attributed, without acceptable proof, to a variety of ovarian disorders. It affects the upper lip, cheeks, forehead and chin and is more apparent following sun exposure. Melasma can be superficial (epidermal) or mixed (epidermal – dermal ) or dermal when the pigmentation is in the dermis. Dermal melasma appears grayish blue in color
DERMATOLOGY and is quite challenging to treat. In superficial melasma, the affected skin is brown in colour. The pigmentary changes are seen over the cheeks, nose, forehead and the chin. Melasma is usually bilateral. RIEHL’S MELANOSIS– It is a distinctive pattern of greybrown facial pigmen- tation. The condition is more frequent in women. Exposure to industrial solvents containing tar derivatives, photosensitizers in cosmetics and fragrances are suspected to be the cause. Brownish-grey pigmentation develops quite rapidly over the greater part of the face but is more intense on the forehead and temples. Smaller pigmented macules, often perifollicular, lie beyond the indefinite margin. The pigmentation may extend to the chest, neck and scalp, and occasionally involves hands and forearms. Horny plugs fill the follicles and there may be some scaling. OCHRONOSIS- It is a bluish grey pigmentation of skin, due to deposition of homogentisic acid in connective tissue. It can be ether due to exogenous or endogenous cause. Exogenous ochronosis is seen with use of hydroquinone prepration and phenol. Exogenous ochronosis is becoming increasingly common in the modern times due to indiscriminate use of skin lightening creams for a prolonged period . Higher concentrations of hydroquinone ( > 2%) are more likely to cause this pigmentation. Milder cases show only macular spotty pigmentation whilst more advanced cases develop irregular stippling, papulation and pigmented colloid milia. These features tend to be most prominent over cheeks and temples. LICHEN PLAUS PIGMENTOSUS- This disorder is commonly seen in India and Middle East. The macular hyperpigmentation involves chiefly the face, neck and upper limbs, although it can be more wides pread, and varies from slate grey to brownish black; it is mostly diffuse, but reticular, blotchy and perifollicular forms are seen. Mucosal involvement can be seen in some cases. ADDISONS DISEASE- Hyperpigmentation in Addison disease is diffuse brownish colour. Predominantly affect sun exposed part. It is more prominent over the creases of palm and soles. Involvement of mucosa like oral, genital mucosa is common. Other features suggestive of Addison disease should be looked in such cases.The hypermelanosis is the result of increased secretion of melanotrophic hormones by the pituitary. Affected patients have elevated plasma levels of β-MSH-like immunoreactivity. CUSHING SYNDROME- Pigmentation is of similar pattern as seen in Addison disease. Seen in around 10% patient of cushing syndrome. It results from increased secretion of ACTH and β-MSH by the pituitary and may suggest the presence of a pituitary tumour. The hair is often darker and there are sometimes multiple lentigines and longitudinal pigmented bands in the nails. HYPERTHYROIDISM- Facial Pigmentation is seen in about 10% cases of primary thyrotoxicosis. It can be

There will be cachectic state with diffuse pigmentation as in Addison’s disease. There can be diffuse slate grey colour pigmentation secondary to melanoma and melanogenuria. LYMPHOMA– Diffuse Addisonian pigmentation can be a rare manifestation of Hodgkin’s disease (10%) and 1 or 2% cases of lymphosarcoma and lymphatic leukaemia. Diffuse progressive hyperpigmentation with pigmented purpura like lesion can also be a manifestation of mycosis fungoides. SYSTEMIC SCLEROSIS, SCLERODERMA AND MORPHOEA- Diffuse pigmentation of face involving predominantly forehead and lateral aspect of cheek and extremity is commonly seen. Reticulate pigmentation of upper back and chest is not uncommon. Along with pigmentation skin is bound down and indurated. Hyperpigmentation in systemic sclerosis is seen most commonly in patients with pigmented skin, and is less common in whites. Keratinocyte endothelin-1 production has been implicated as playing a central role in the pathogenesis of cutaneous hyperpigmentation in systemic sclerosis, as has local expression and systemic release of a stem cell factor.Pigmentation may also be a conspicuous feature of morphoea and is occasionally the presenting symptom. LUPUS ERYTHEMATOSUS- In systemic lupus erythematosus, diffuse pigmentation of light-exposed skin occurs in about 10% of cases. It may gradually darken, although the disease is controlled by treatment. RENAL FAILURE– Diffuse hyperpigmentation of face and hand is common in chronic renal disease. ANAEMIA- Vitamin B 12 deficiency can cause mottle and dapple pigmentation of face, hand and feet. Occasionally folic acid deficiency can cause diffuse pigmentation. PRIMARY BILIARY CIRRHOSIS- Hyperpigmentation is particularly striking on sun-exposed sites.

OCCLUSION Whilst composite and porcelain laminate veneers may fracture due to a random event such as biting on a hard object, most fractures result from nocturnal para functional clenching or grinding on laminates that encroach upon the occlusal envelope, often at the physiological limits of mandibular movement.
ESTHETIC DENTISTRY Patients and dental personnel must wear protective glasses when using TCA. Do not use Sodium Bicarbonate solution in the eyes. Neutralizing Solution Make up a solution by adding a spoon full of NaHCO3 to a proprietary Chlorhexidine Mouthwash. This will prevent bacteria from growing in the solution as would occur if straight tap water was used. Have the solution on hand whenever TCA is being applied.
Patients are usually unaware of such activity and clenching or bruxing is diagnosed by aligning upper and lower incisal wear facets, usually with difficulty and complaints from the patient. The wear facets will align at or near the limits of mandibular movement and the cause of persistent fractures will often become evident.
IN CONCLUSION Placing direct laminate veneers without tissue preparation is compatible with the philosophy of minimal intervention aesthetic dentistry and encourages better informed patients to seek out such practitioners. Upon mastering direct laminates a clinician is in a position to expand these skills to include single composite resin crowns, the placement of direct resin bridges and more complex clinical applications such as rebuilding vertical dimension for patients with gross occlusal wear.
CAUTION WITH THE USE OF TRICHLOROACETIC ACID TCA is a powerful chemical cauterizer and astringent that arrests gingival exudate and reduces the possibility of cervical staining. Place a small amount in a Dappen’s dish and transfer the acid to the mouth with a perio probe. The white eschar that forms on the gingivae is self limiting and will usually have disappeared by the completion of the procedure without scarring or gingival recession. Patients feel no pain when it is applied to gingival tissues or oral mucosa. If the acid inadvertently contacts a patient’s skin, it can be readily neutralized with a solution of Sodium Bicarbonate swabbed over the contaminated surface.

WHITENING VS. BETTER ENAMEL CARE (ACP WHITENING) – ‘WANT’ OR ‘NEED’ BASED DENTISTRY?
Dr. Rumpa Wig
Recap previous articles
Myth 1: 8 – 10 shades possible? What does it mean? Factual Truth 1: Re-arrange shade guide as per chroma(light to dark) and not on hue (colour) . Result of 10 shade jump is achieved fastest with an in-office power bleach system. Myth 2: Higher the concentration peroxide … better the result? Factual Truth 2:Just because you use the highest peroxide does not mean you will get the best possible whitening result. In fact you are advised by the ADA to use peroxide of as low a concentration as possible. The role of catalysts and sensitivity markers have been proven to aid whitening and optimal results can be obtained with lower concentrations of peroxide. Myth 3: Do Tooth Whitening lights really work to better whitening results? FactualTruth:It’s not the light but the chemistry between the light and gel that needs to be checked. Most lights have heat chemistry with the gel to hasten oxidation. This just hastens the effect, does not better it. Lights like ‘Zoom’ have a photo-reactive chemistry with the gel that betters whitening 3 times with minimal heat. Therefore it uses only 25% hydrogen peroxide. B1 in 45 minutes in most patients.

Facethetics | Issue 3 Vol. 1
Myth 4 : Is Fluoride the final authority on sensitivity? Factual Truth 4: No. Fluoride is not the final authority on sensitivity management. It is best achieved in combination of ACP (amorphous Calcium Phosphate) + Fluoride + KNO₃. ACP is a very important new entrant in management of sensitivity as it enhances the uptake of fluoride and synergistically aids enamel care to result in much better sensitivity management than achieved by fluoride alone. Proven and supported by the ADA.
MYTH NO 5:WHITENING IS ‘WANT BASED ‘DENTISTRY! Should treatment focus be Vanity or Dentistry?
INTRODUCTION Do we really have a definition for ‘want’ based and ‘need’ based Dentistry? What we do have is a broad perspectiveof ‘want’- based and ‘need’- based dentistry. Simply, ‘want based’ would be that which the patient asks for and is not a critical need of the hour. ‘Need based ‘ dentistry would be that which is the need of the hour or when treatment is given when the patient is in difficulty or in pain. Most of our practices are devoted to ‘need based’ dentistry merely because that is the bulk of the patients we get.
Jan-Mar 2015 People do not want to come to the dentist unless they have a problem to address.
ESTHETIC DENTISTRY WHAT PATIENT RESPONSES DO WE EXPECT WITH THESE NEW PARADIGMS ?
We are a little different from the western world. They have patients that come into a dentist’s office with requests that are not need based. That’s probably because they come in for hygiene appointments, are comfortable with the clinic and then are very aware and comfortable seeking additional work done to enhance their smiles. Western Dental offices also are much more aggressive in offering treatments with special offers than Indian offices are. Since we do not have typical hygiene departments in our dental offices we tend to miss out on entire section of society till the need arises.

THE NEED OF THE HOUR IS THAT WE ADDRESS THE WANTS OF OUR PATIENTS MORE EXPLICITLY , AND IN DOING SO ,ALSO TAKE CARE OF THEIR NEEDS!
We have touched upon this subject in every article, but today it is the only topic of focus as it is the future of Whitening and deserves special attention in your practice.
Whitening has remained an appointment that is given out , if the patient asks for whitening.
WHAT IS ACP?
In this article , I humbly attempt to change that myth , that keeps whitening in the domain of vanity – ‘beauty without a purpose’ and therefore a ‘wantbased’ treatment! Whitening ,when done right , does not need to be a ‘want’ but can actually be a platform where you can address more than just whitening ! We need to transform the bleaching appointment into a Pro-active Care appointment or ‘need to change the health of your enamel before trouble comes’ kind of appointment. You possibly cannot change the health of enamel by keeping it dirty yellow or brown. The colour of health on the enamel is WHITE. Sounds Interesting? It is, especially when the hygiene appointment is not interesting enough to get the patient on the chair regularly to address his needs in time. Let’s get started.
PARADIGM SHIFTS REQUIRED BY THE CLINIC 1.
Patient’s tooth Smile is the Dentist’s responsibility.
2.
Active care to Proactive care. Protecting and highlighting smiles are also our responsibility.
3.
Heal to health to Beauty. Dental health comes before vanity.

Progression of treatment –
WHAT IS ACP WHITENING?
ACP is an abbreviation for Amorphous Calcium Phosphate. ACP is created when dissolved Calcium ions and phosphate ions react to form a non-crystalline insoluble salt. Due to the reactive nature of the chemicals involved, the calcium and phosphate must be stored separately until they are applied to the tooth surface. You will find them dispensed in dual barrel syringes. Tooth demineralization from acid results in dulling, loss of tooth luster, and a higher susceptibility to caries. The oral environment can naturally rebuild enamel, through a process called remineralization, to some extent on its own, but the extent of remineralization is controlled by pH and the amount and availability of calcium and phosphate ions present in the mouth. Remineralization can easily be reversed in an under-saturated environment. The rebuilding of enamel is a slow kinetic reaction which can be rapidly sped up by the addition of ACP-forming components into the oral environment. Amorphous Calcium Phosphate (ACP) is the reacted complex of calcium and phosphate ions that precipitate and can grow on tooth surfaces in the oral environment.

ESTHETIC DENTISTRY HOW DOES ACP WHITENING WORK?
Jan-Mar 2015 Effective Desensitizer ACP mimics the natural desensitizing process by eliminating the source of sensitivity by plugging dentinal tubules with calcium phosphate, the tooth mineral. This is similar to the process of sclerosis, where salivary mineral precipitates slowly over time in these tubules and reduces sensitivity. ACP simply speeds this process considerably with the same mineral at much higher concentrations. ACP has been clinically shown to dramatically reduce dentinal hypersensitivity by occluding dentinal tubules. Philips-Discus Dental whitening gels, such as Nite White ACP, Daywhite ACP , Dash , Zoom Whitespeed ,are the only professional whiteners to combine patented ACP technology with the proven effectiveness of Potassium Nitrate to establish a new standard for patient comfort in professional whitening.
ACP WHITENING ISA 3 PRONGED ACTION PLAN! 1. Whitening 2.
Fluoride & KNO₃
3. ACP The differentiating factor is ACP ! Peroxide, fluoride, potassium nitrate and ACP are dispensed in a dual barrel syringe to provide a fresh blend of a multi-action system that : - heals surface defects, - remineralises, - strengthens and protects the enamel while whitening.
BENEFITS OF ACP WHITENING Rebuilds Enamel The deposition of hydroxyapatite onto teeth rebuilds enamel and restores luster through a process called remineralization. Preliminary research by Flaitz & Hicks at the University of Texas, Huston, showed that, “The addition of calcium phosphate to whitening agents reduces the susceptibility of enamel to in-vitro lesion initiation and progression.”

Improved Appearance – Restores Enamel Luster ACP has been clinically shown to improve the smoothness and luster of teethby filling superficial tooth defects and improving the overall smoothness and luster of patients’ smiles.
Jan-Mar 2015 Lasting Results In clinical studies, patients who used a take-home dental tooth whitener containing ACP experienced less fadeback six months after treatment compared to patients who used an identical take-home whitener without ACP.DA
ESTHETIC DENTISTRY “NEED” for PROACTIVE CARE,‘OralWELLNESS’called lifestyle dentistry which is the order of the day! That it adds to your bottom lines, only helps the cause. A word of caution, patients are well-informed and they will catch up to ACP whitening earlier than you might ! Food for thought: Patients are looking for whitening. Does your office suggest that you are ahead of the game with treatment options that are both appealing and actually good for your patients? A professional Dental Office has to do more than ‘look good ‘and ‘feel good’ ….. It has to DO GOOD.

CONCLUSION Bleaching is a ‘want based’ treatmentoption.‘ACP whitening’ is not! With ACP whitening, it is easier to promote oral health,wellbeing and healing to preserve and conserve what nature gave us before we promote Cosmetic Dentistry. We now have a tool that helps us reverse neglect and get our enamel back to shape. Patients get it, if we project it in the right way. Being in shape is not a one-time exercise. Easy Regular care goes a long way to preserve and protect your enamel. It has to be hygiene, whitening and finally ‘health of enamel’ that is the protocol for whitening success. “WANT”now metamorphs into

PRINCIPLES OF CREATING A SMILE THE CONCEPT OF BIO-ESTHETIC DENTISTRY Dr. Vinisha Vipin Sharma
In our modern competitive society, a pleasing appearance often means the difference between success and failure in both our personal and professional lives. Scottish physiologist Charles bell (1774-1842) was quoted as remarking that the thought is to the word that the feeling is to the facial expression. He pointed out in 1806 that a smile could convey a thousand different meanings, yet it is the most easily recognized expression. And because the mouth is one of the focal points of the face , it should come as no surprise that the smile plays a major role in how we perceive ourselves, as well as in the impressions we make on the people around us. A charming smile can open doors and knock down barriers that stand between you and a fuller, richer life. An attractive or pleasing smile clearly enhances the acceptance of the individual in the society where he belongs and the character of the smile influences to the great extent the attractiveness and the personality of the individual.
SMILE DESIGNING Is a process whereby the complete oral hard and soft tissues are studied and evaluated and certain changes are brought about which will have a positive influence on the overall esthetics of the face. These changes are governed by the principles of bio-esthetic dentistry. Hence, a good smile

design would naturally and effortlessly blend with the rest of the face to provide an esthetic and functional complex.
PRINCIPLES The Principles of Smile Design govern how naturally attractive your smile is – or isn’t! When art, science, form and function are blended optimally by nature or an experienced cosmetic dentist, the results can be simply amazing! Experienced cosmetic dentists understand and use these principles to transform dull average smiles into successful confident smile. 1. Central incisor width/height ratio The width/ height ratio should be 80 %. For example if width were 8.0 mm and the height 10 mm, the ratio (8/10) would be equal.
Jan-Mar 2015 2. Mesial Inclination Each upper tooth visible during smiling should have a slight inclination or tilt that is towards midline of the mouth.
ESTHETIC DENTISTRY 5. Smile at rest 2-4 mm of upper teeth should be visible at rest. This amount decreases with age as the window of the mouth begins to sag downwards showing more of lower teeth.
Surprisingly if these lines are extended downwards they would meet or converge at or near navel point of stomach.
3. Midline The position of the midline between the central incisors should be a line drawn from between the eyes down through the nose, lips and chin. The angle of the midline should not be tilted to the left or right, but should be straight up and down.
4. Colour and shade The teeth should be uniform in colour and shade. The presence of stains, markings necessitates the treatment for the same.
6. Gingival symmetry The gum tissue frames the teeth and forms a curtain for the teeth. The gingival margin should be scalloping and symmetrical on both the sides. Balance and symmetry are important for an attractive smile.
7. Gingival margin height The height of gingival margin over the lateral incisors should be slightly lower than the height of gingiva over adjacent central incisor and canines.

ESTHETIC DENTISTRY 8. Gaps/ Diastema Diastemas are unsightly gaps present between the anterior teeth. They should be restored with full coverage crowns or composite restorative material.
11. Smile Line The incisal edge of the maxillary central incisors should be parallel or follow the contour of lower lip at rest or when smiling.
9. Gummy/ Gingival smile When an excess of gingiva superior to the maxillary anterior teeth is displayed upon full smile, it is termed a gingival smile. The gingival smile is known by a variety of terms including “gummy smile, high lip line, short upper lip, and full denture smile.” Ideally 1-3 mm of gingiva should be visible above the teeth.
12. Horizontal plane The left to right horizontal biting plane of the mouth should parallel the floor or horizon when standing. It should also parallel a line drawn between eyes i.e. inter papillary line.
10. Gingival Zenith The upper most height of gingival margin over each tooth is called the gingival zenith. The height of the gingival margin over each tooth varies from tooth to tooth. It should be centered over each lateral incisor and should be 2/3rd of the way across the face of the tooth for central incisors and canines.

13. Gingival health Healthy coral pink gingival is indicative of a good gingival health. For an attractive smile gingiva should be free of calculus and bleeding or halitosis.
Jan-Mar 2015 14. Contact points The contact points between two teeth should step upward with each tooth. They should not gradually migrate upwards from tooth to tooth.
15. Crowding or Mal-alignment Crowding is usually present if there is lack of space for teeth to erupt or if the jaws are too small. Mal-alignment of teeth lead to lack of oral hygiene maintenance and poor facial and esthetic appearance.
16. Incisal Embrasures The silhouette between front teeth should be triangular in shape i.e the outline shape between incisors should symmetrically increase in size moving away from the midline. A good definition and separation between incisal edges of front teeth is indicative of a harmonious smile.
17. The Golden proportion The Golden Proportion is an art of ages follows the “rule of thirds”. It is used as a tool by the cosmetic dentists to create a pleasing smile that is balanced with the face. It states that each tooth away from the midline should be
ESTHETIC DENTISTRY two-thirds as wide as the previous tooth. For example: Measure the width of a central incisor in your mouth or on a photograph. Divide this width by the width of the lateral incisor next to it. The central incisor should be 1.6 times as wide as the lateral, and the canine 0.6 times as wide as the lateral, and so forth. (Example: Ideally, if the central incisor is 10 mm wide, the lateral incisor should be twothirds of this amount, or about 6.5 mm, and the canine should be two thirds of that or about 4.4 mm).
18. Black triangle It is the spacing between anterior and posterior teeth due to underlying bone loss. When this process takes place underlying gingival papilla shrinks which allows darkness from the back of teeth to show through and mimic a black triangle.
19. Anterior guidance The relationship of anterior teeth with function is also an important for determining a balanced occlusion. The contour and position of upper and lower anterior teeth is so critical that even a millimeter in incisal edge location can be unacceptable to some patients. 20. Vertical dimension The loss of vertical dimension makes your face appear older. The vertical distance between the nose and the chin can be short due to improper growth and development of the jaws and deep bite, or because of attrition or missing teeth. As a rule of thumb, the measurement between the marginal gingival and central incisor edge on occlusion averages between 17-21 mm. For most people this creates a vertical proportion to the lower 1/3rd of the face that is pleasing to the eye.
