ABSTRACT: Aim: The aim of this study was to assess prevalence of dentinal hypersensitivity and its association with diet and dietary habits among adults aged 18–30 years. Methods: A total of 389 subjects aged 18-30 years who reported to our institution with dentin sensitivity were considered. The questionnaire was given to subjects and were requested to complete the questionnaire and revert. Information about demographic data such as age, sex followed by details of their diet types; dietary habits and other associated habits were recorded. Results: Prevalence of dentinal hypersensitivity was found to be 44%. The subjects having dentinal hypersensitivity consumed more fizzy drinks with meals (OR=4.30), Aerated drinks (OR=3.04), consumption of fizzy drinks (OR=1.75) consumption of green leafy vegetable and junk foods along with sweet candies was not statistically associated with dentinal hypersensitivity (p<0.05). Twice brushing and use of fluoridated tooth paste did not yield a significant odds ratio. Conclusion: Consumption of fizzy rinks, aerated drinks has higher chances of developing dentinal hypersensitivity.
