Aim: The aim of this study was to assess dental and skeletal development in obese and normal-weight pediatric patients.Materials and Methods: A sample of 65 patients (33 boys, 32 girls aged between 9 and 15) was selected. Dental panoramicradiographies were used for determining the dental age. Dental age was evaluated using the Demirjian Method scoring system.Skeletal age was measured by hand wrist radiographies using Greulich and Pyle method. The data were analyzed by MannWhitney U and Independent t-tests.Results: There was no statistically significant difference between the obese and normal-weight groups in terms of dental age(P> 0.05). Skeletal age was significantly increased in obese boys (P <0.05); however, there was no significant difference ingirls(P> 0.05).Conclusions: Paediatric dentists should consider body mass index percentile when assessing growing children because it canaffect dental and skeletal development.
