Aims and Objectives: The cardiovascular diseases (CVDs) all over the world results in huge disease burden that has catastrophic social and economic effects. The main objectives of this study are to explore possible association of bruxism with CVD and to document other factors associated with (CVDs) and bruxism. Subjects and Methods: It is an observational study done in two hospitals of district Kangra, Himachal Pradesh. A case–control study design was used to study the association of bruxism and CVDs. Cases were patients having history of CVDs and controls were without CVDs. Self-reporting questionnaire and tooth wear index were used as research instruments. Results: A total of 80 subjects with CVD (62 years, standard deviation [SD] - 11.8, 53% men) were compared with 80 controls (58.9 years, SD - 11.15, 55% men). Bruxism was found to be more prevalent in patients with CVD (71.3% vs. 57.3%, P = 0.00043). On multivariate logistic regression analysis, bruxism was independently associated with CVD (adjusted odds ratio (OR) 2.61, 95% confidence interval [CI] 1.2–5.8, P = 0.016 and an unadjusted OR 3.16,95% CI, 1.66–6.21, P = 0.000529), explaining that the odds of having CVD is 3.16 times higher in patients with bruxism than participants without bruxism. Conclusions: More research (cohort studies) needs to be conducted to find the emerging risk factors for CVDs. Through the help of dentists, doctors, and community health workers, the general population shall be made aware of bruxism, CVDs, and their possible association.
