Aim: To evaluate the association between anthropometric measurements and dental caries in school children. Methods: The study was conducted on 245 primary school children (50.2% boys, 49.8% girls,), aged 5 to 9 years. The prevalence and severity of dental caries was measured using the decayed, missing or filled surfaces (dmfs, DMFS) and teeth (dmft, DMFT) indices. Results: Mean dmft indices in children for boys and girls were 5.5±3.92 and 5.0±3.64, respectively. The prevalence of children with dental caries (dmft ≥1) was 84.9%. The prevalence of children with body mass index (BMI) <−1SD and ≥+1SD was 15.9% and 22.9%, respectively. Dental caries were found in 89.7% of children with low body weight (including underweight and at risk for underweight) and in 66.1% of overweight-obese children (p<0.05). Similarly, high indices were detected significantly more often in children with low body weight (p<0.
