PERFECTION AND COMFORT IN TEETH WHITENING
13323 Views - Jan 2016 The desire for having white teeth has been phrased for a long time. The light and bright tooth color has even been a very essential aesthetic aspect when the teeth alignment and symmetrical appearance was not of primary importance. A beautiful smile does not only reflect neatness but also helps people feel more confident and has a very significant role in socialization. The technical and technological development of the dental profession has enabled us to change the natural teeth color by non-invasive, chemical methods. Bleaching materials and techniques have gone through several generations and they are considered to be conservative and tolerant methods in fulfilling the desire for white teeth. Due to the above-mentioned circumstances tooth whitening has gained ground in the treatment profile of the dental offices. In the earlier times the “Nightguard”, later the techniques known as at-home tooth whitening systems used a gel of 10-20% carbamide peroxide with individual tooth whitening trays. Then lower concentration (6-8%) materials and absolutely universal tray setups appeared. The improvement in the tooth whitening home kits focused on increasing convenience and decreasing using time. Based on the achieved results these are considered to be the most tolerant kits nowadays. However, sensitivity attributed to these systems could not been successfully eliminated. As regards the individual structural distinctiveness of the dental enamel, sensitivity has been described from moderate to certain feel of pain character. Almost all the patients complained of sensitivity discomfort during the use of the tooth whitening home kit and some days after the treatment as well. The past tooth whitening products containing hydrogen peroxide have been replaced by products containing carbamide peroxide but this fact has not solved the problem. Unfortunately the aetiology of bleaching-related tooth sensitivity is neither well understood nor easily measured; however the hydrodynamic theory is a mechanism frequently cited to explain it. According to this model, peroxide solutions introduced into the oral environment contact available dentinal surfaces and cause retraction of odontoblastic processes, resulting in rapid fluid movement inside the dentinal tubules. This ultimately manifests in stimulation of mechanoreceptors at the pulp periphery, with the resultant feeling of pain when such teeth are exposed to cold or pressure, or even when they are at rest. As a result of the latest improvements a new bleaching product has appeared. Its molecule eliminates the tooth sensitivity problem. This is the WHITE DENTAL BEAUTY with an active ingredient called NOVON. This patented active ingredient has a novel inherent feature, in that it remains stable at neutral pH in the syringe, yet upon dilution a rapid pH increase occurs. This pH increase, from neutral to alkaline, produces an enhanced release of perhydroxyl ions resulting in a more effective bleaching action. Novon’s unique formula gives White Dental Beauty gel an unsurpassed accelerated bleaching action which is safe, effective and kind to the teeth. Page 1 of 8
