Background:Dentine hypersensitivity (DH) is a relatively common problem which may affect the adult population. The etiology remains multi-factorial with interactions between stimulus and pre-disposing factors causing its aggravation.Aim:To study the prevalence of DH and associated factors and also to find the association between various factors and DH.Materials and Methods:A cross-sectional study was carried out and a total of 5091 patients, both male and females, were evaluated through questionnaire. Out of the total only 1400 patients were included in the study and were further evaluated clinically. A complete demographic data was obtained and the DH was confirmed by the use of air -water jet of the dental chair and scratching the suspected tooth with a dental probe. The pain response of the subject was recorded using the visual analog scale (VAS) and verbal rating scale (VRS). The data obtained was statistically evaluated and Chi-square test was applied for comparison of different demographic factors with DH.Results:The overall prevalence of DH was 27.4%. Various demographic factors were found to affect DH such as age, gender, education, and diet. The most common stimulus was found to be cold (21.4%) and common predisposing factor was gingival recession and attrition (28.6%). Clinical examination yielded a statistically significant association between VAS and VRS scores for DH and demographic factors.Conclusion:The prevalence of DH in present study was 27.4% which is attributed to gingival recession as predisposing factor and cold stimuli as the precipitating factor.
