Background: Dental caries and obesity are prevalent chronic conditions across all age groups, with common multifactorial causes such as diet and socioeconomic status.
Objective: The aim of this study was to determine if there is a correlation between the decay missing filled tooth (DMFT) index and body mass index (BMI) in preschool children.
Materials and Methods: The study included 390 children aged 4 to 6 years, comprising 262 boys and 128 girls. The DMFT indices were assessed by two dentists, while anthropometric measurements were conducted by a nutritionist. BMI was calculated using the WHO AnthroPlus application.
Results: Most children were of normal weight (332), with 28 being underweight and 30 overweight. There were no obese children. Underweight children had a mean DMFT index of 3.7 ± 3.56, significantly higher than those of normal weight (2.0 ± 1.88) and overweight children (1.9 ± 1.60).
Conclusions: This study highlighted an association between the DMFT index and BMI in preschool children, with underweight children having a higher DMFT index compared to those of normal weight and overweight.
