[Dentin hypersensitivity and its significance in dental practice]

Dentin hypersensitivity is not a new disease, more than a hundred years ago Gysi, later Brännström and many others were dealing with the problems of its symptoms, pathomechanism, differential diagnosis and therapy. The growing interest today maybe attributed to improving oral health, and to the presence of more teeth in older age, as a consequence of decreasing caries prevalence. The exposure of dentine surfaces due to gingival recession, erosion and abrasion may cause serious complaints, occurs in about 40% of the adult population, however, few of them turn to the dentist. Therefore, practising dentists should be aware of the possibilities of treatment, managing strategies and prevention. New aspects are the appropriate timing of toothbrushing after consumption of acidogenic, erosive foods and beverages, non-invasive (desensitizing, potassium-nitrate/fluoride containing toothpastes), and invasive (reconstruction with fillings, coverage of the exposed roots) treatment options. Continuous care of patients suffering in dentine hypersensitivity--in order to prevent more serious consequences (irritation of the pulp)--is advisable.
