Abstract
The aim of this study was to investigate the prevalence of dental anomalies in different body mass index (BMI) percentile child and adolescent subjects. Panoramic radiographs of 186 subjects (68 males and 118 females) were evaluated. The subjects were divided into three groups according to BMI percentile: Normal-weight (93), overweight (40), and obese (43) subjects. Supernumerary tooth, tooth agenesis, dens invaginatus, dens evaginatus, tooth impaction, taurodontism, pulp stone, and root dilaceration were assessed. Root dilaceration was found in 11.3% of the obese subjects and 17.5% of the overweight subjects. There was a statistically significant difference in the root dilaceration prevalence among the groups (p=0.015). However, other dental anomalies did not display statistically significant differences among the groups (p>0.05). While there was no statistically significant difference in the dental anomalies prevalence among different BMI percentile groups in males (p>0.05), a statistically significant difference in the root dilaceration prevalence was detected among different BMI percentile groups in females (p=0.036). The data were analysed using chi-square and Fisher's exact tests. The prevalence of root dilaceration was significantly greater in obese and overweight subjects than in normal-weight subjects.
