Abstract
Objectives: This study aims to assess the relationship between the body mass index and waist circumference, which are indicators of obesity, and dental caries according to gender.

Methods: Data were used from the 6th Korean National Health and Nutrition Examination Survey (2013-2015).
Out of a total of 29,321 subjects, 13,222 persons aged 19 or older and who responded to the survey items of this study were selected as subjects to determine the relationship between obesity and dental caries.

Results: In the body mass index, the obese group had a higher prevalence of dental caries in both males (1.25 times) and females (1.35 times) than the normal group. Even in the underweight group, males were 1.83 times more likely to have dental caries than the normal group. In the waist circumference, the obese group had a 1.48 times higher prevalence of dental caries than the normal group in women only.

Conclusions: According to the results of this study, it was observed that obesity was related to dental caries, and it was thought that obesity management and oral care education programs for adults in Korea were necessary.
