Aim:
The aim of this study was to investigate the prevalence of dental anomalies in different body mass index (BMI) percentile child and adolescent subjects.
Materials And Methods:
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.
Results:
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.
Conclusion:
The prevalence of root dilaceration was significantly greater in obese and overweight subjects than in normal-weight subjects.
