Background and Aim: Tooth decay as a significant but preventable public health priority continues to be a common disease in developing countries, including Iran, which is particularly prevalent among children. The present study aims to determine dental caries prevalence among elementary school students and its relationship with body mass index and oral hygiene in Ardabil, Iran in 2019. Materials and Methods: This cross-sectional study was conducted on 581 elementary school students selected through cluster random sampling method in Ardabil city in 2019. Demographic data was collected using questionnaire and anthropometric indices (height, weight) were measured using the weighing scale and stadiometer, and dental caries was evaluated using the decayed, missing, or filled teeth index (dmft for primary teeth and DMFT for permanent). Results: The mean age of students was 9.61 ± 1.76 years, and 50.8% of them were female. 20.7% (n = 120) were obese, and 19.1% (n = 111) were overweight. The overall prevalence of caries was 74.9% (n = 435) in primary teeth, 72.8% (n = 423) in permanent teeth, and 96.6% (n = 561) in all teeth. The average dmft and DMFT scores were 4.16 ± 3.72 and 1.96 ± 1.76, respectively. There was a significant inverse relationship between body mass index and dmft (r = −0.146, P < 0.0001) and DMFT (r = −0.111, P = 0.004). Conclusion: The findings showed that prevalence of dental caries in elementary school children in Ardabil city is higher than global standards, obese and over-weight children experience fewer caries compared to normal-weight children, and there is a significant relation between not brushing the teeth and dental caries.
