Dentine hypersensitivity is one of the most common problems in general clinical dentistry today, causing discomfort and negatively affecting patient's quality of life. It is characterised as short and sharp pain arising from exposed dentine in response to an array of thermal, mechanical, chemical and osmotic stimuli. Dentine becomes exposed due to enamel loss or gum recession, the causes of which are many. The treatment and management of tooth sensitivity often involves a combination of several different therapeutic regimens, depending on the extent and degree of severity. Non-invasive approaches are usually used first before surgical procedures are performed. These mainly include products for at-home use, which also include cosmetic products for maintaining oral health.
In the diploma thesis, we studied the composition of cosmetic products for reducing teeth sensitivity. We randomly selected 51 cosmetic products from pharmacies, drugstores and online stores and focused on their cosmetically active ingredients. We devided them into agents for dental tubule occlusion and for nerve desenzitation. We also took a look at the most common auxiliary substances, namely abrasives, surfactants, preservatives and investigated the potential effects of plant extracts. Paste was the most prevalent form of selected cosmetic products We have listed 7 different groups of cosmetically active ingredients for reducing tooth sensitivity. Among agents for tubule occlusion dominated stannous salts, which were present in 18 % of products. Potassium salts are the only agents for nerve desensitization and are also the largest group of active ingredients (22 %). Fluorides were present in 57 % products. The most common was sodium fluoride, which we listed in 42 % of products. Among abrasives, sodium dioxide was the most common and which we listed in 97 % of the products with abrasives. We devided surfactants by charge into 7 anionic, 6 nonionic and one amphoteric. The latter is cocamidopropyl betaine, which was the most common surfactant (35 %). 63 % of products contained preservatives. Amongts them dominated sodium benzoate, which was present in 41 % of cosmetic products. We have listed more than 30 different plant extracts and essential oils. Some show potential for reducing dentine hypersensitivity.
