Abstract:

Background: Dentin hypersensitivity (DH) is a clinical condition with potential implications for patients. However, little is known about its occurrence and determinants in the general population. The aim of this study was to assess the prevalence and risk indicators of DH in Porto Alegre, Brazil. Methods: A representative multistage probability sample of 1,023 adults aged >/=35 years was obtained. Individuals were interviewed and were clinically examined in their homes. DH was assessed dichotomously in all present teeth by a blast of air and a manual probe. Teeth restored with crowns and presenting with carious cavitation were excluded. Survey logistic regression using sampling weights was applied to assess demographics, behavioral and clinical determinants. Results: Overall prevalence estimates for DH diagnosed by air and probe were 33.4% and 34.2%. DH affected 1.0 tooth per individual, and approximately 10% of teeth with gingival recession (GR) had DH. In a multivariate model for DH diagnosed with air, females had increased chance of DH [odds ratio (OR): 2.14; 95% confidence interval (CI): 1.57-2.91]. Smoking, periodontal treatment, and GR were also associated with increased DH chances. The chance of DH was lower (OR: 0.47, 95% CI: 0.29-0.76) among individuals >/=60 than 35 to 49 years old. Oral hygiene practices, socioeconomic and educational statuses, dental visits, and gingival inflammation were not associated with DH. Conclusion: DH may be considered a concern in a Brazilian general population. Reduction of DH may be achieved by smoking cessation and periodontal health improvements.
