Aim: To evaluate the correlation between dental caries and obesity in 8–10 years school children of Chandigarh, India. Materials and methods: Around 100 children of the age range of 8–10 years who attended the Pediatrics OPD of Dr Harvansh Singh Judge Institute of Dental Sciences & Hospital, Chandigarh, India were selected. Four groups were made group I—25 healthy teeth and nonobese (HNO) children, group II—25 carious teeth and nonobese (CNO) children, group III—25 healthy teeth and obese (HO) children, and group IV—carious teeth and obese (CO) children. Caries score was recorded after careful examination. Stadiometer and balanced beam scale were used to measure height (m) and weight (kg), and body mass index (BMI) (kg/m²) was calculated. One-way analysis of variance (ANOVA) and Mann–Whitney U tests were used to assess the data outcome. Results: The overall mean BMI was 26.2 [standard deviation (SD) = 5.2). Nonparametric test was performed using Poisson regression which showed no significant association between BMI and decayed, missing, and filled teeth/decayed, extracted, or filled (DMFdef) (p = 0.807). The severity of dental caries was evaluated by using a multivariate logistic regression analysis to see the association between dental caries as a binary dependent variable (low and high), and BMI as the independent variable. Statistically insignificant results were obtained (p = 0.841). Conclusion: The study conducted by us showed no association between caries and obesity but the long-term effect of caries on general health cannot be ignored. The proper measures which are taken to improve oral health can indirectly alter the risk factors for obesity thus improving both oral and general health of an individual.
