AN ANALYSIS OF AETIOLOGICAL FACTORS RELATED TO DENTIN HYPERSENSITIVITY AND SEVERITY

Purpose: in management strategies of dentinal hypersensitivity, aetiological and predisposing factors should be taken into account rather than the treatment alone. the aim of this study was to determine the prevelance and aetiological factors of dentinal hypersensitivity and evaluate relationship to severity. material and methods: the subject population was consisted of 173 patients. all patients were evaluated in respect to aetiological factors related with or without hypersensitivity. also severity of dentinal hypersensitivity was recorded by using visual analoque scale. result: in the survey population, dentinal hypersensitivity was observed as 40,4 % of which was 13,3 % gingival recession, 9,2 % attrision, 5,8 % periodontal disease, 5,2 % abrasion 4,6 % erosion and 2,3 % abfraction. mean values of visual analoque scale of the factors leading to the dentinal hypersensitivity were observed 4,28 in erosion, 4,25 in abrasion, 3,70 in gingival recession, 3,45 in abfraction, 2,94 in periodontal disease and finally 2,65 in attrision. conclusion: this study showed that although attrision followed by gingival recession was the most common aetiologic factor of dentinal hypersensitivity, patients were more affected by non-carious cervical lesions in respect of severity of dentin hypersensitivity.
