Objective: To assess the prevalence of dentine hypersensitivity (DH) in an adult population and explore association with sociodemographic variables, dietary habits and oral health behaviours. Design and Methodology: Cross-sectional survey of consecutive dental patients (18 years and over) attending the UWI School of Dentistry polyclinic. Following informed consent, dental examinations were undertaken by two calibrated dentists. Presence of DH was assessed clinically by sensitivity to an air syringe on individual teeth. Patients were also administered a questionnaire which included age, gender, occupation, medical and dental history, brushing and dietary history. Data were processed using statistical software (SPSS version 24). Association between variables were analyzed using the Chi-Square test. Results: 300 patients participated. Age range 18 ­ 81years, mean 44.7 years (SD 15.69). 69% were female and the main ethnic groups were African (45.7%),Indian (30%) and mixed (23%). 48.3% were in employment. Over half of the participants (54.9%) reported a history of sensitive teeth and 52% reported sensitivity to the air syringe on one or more teeth. A history of sensitive teeth was significantly associated with gender (female), frequent consumption of citrus fruits and citrus juice, history of teeth grinding or clenching and twice daily tooth brushing (Chi-square test p <0.05). Conclusions: Prevalence of dentine hypersensitivity was high among this sample of dental patients and associated with gender, dietary practices, tooth grinding and brushing frequency. Management of this condition should include dietary advice, modification of oral habits and advice on tooth brushing techniques.
