SILVA, Bruno Stênio da et al. The Occurence and Risk Factors of Dentin Hypersensitivity. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2011, vol.11, n.1, pp. 99-105. ISSN 1808-5210.

The aim of the present study was to verify the occurrence of cervical hypersensitivity (CHS) in the dentin and risk factors among patients seeking care at the policlinic of the Faculty of Dentistry, University of Pernambuco (Brazil) and assess the treatment need. An analytical cross-sectional study was carried out involving 99 patients, 39 (39,39%) of whom were diagnosed with CHS, which was assessed by touching a clinical probe to the exposed surface of the tooth with light pressure and a one-second jet of air on the area with gingival recession. The prevalence of CHS is worrisome. Individuals who used more abrasive toothbrushes, those who underwent periodontal treatment in the previous three months and those with gastric reflux had a greater chance of exhibiting CHS. The occurrence of CHS was high in the population studied, demonstrating that dentists should give greater attention to the diagnosis of this condition. The consumption of acidic drinks and foods, brushing with toothbrushes with more abrasive bristles, poor oral hygiene, periodontal treatment and gastrointestinal problems are important etiological factors associated to this condition. Further population-based studies are needed to assess the prevalence and determinants of CHS.
