RESUMO
INTRODUCTION: The purpose of this study was to determine whether increased body mass index is associated with accelerated skeletal maturation. METHODS: The skeletal ages of 107 children, aged 9 to 16 years, were determined by using Fishman's hand-wrist analysis. The difference between chronologic age and dental age was analyzed against body mass index, sex, and age. RESULTS: The mean differences between chronologic and skeletal ages for normal weight, overweight, and obese subjects were 0.51 years, 0.44 years, and 1.00 years, respectively. Although there was a trend for obese subjects to have accelerated skeletal maturation compared with overweight and normal-weight subjects, the difference was not statistically significant. Skeletal age differences significantly decreased with increasing age. The mean skeletal age differences were 0.90 year for 9- to 13-year-olds and 0.26 year for 13- to 16-year-olds. Mean skeletal age did not differ significantly by sex. CONCLUSIONS: Overweight or obese children did not have significantly accelerated skeletal maturation after adjusting for age and sex.

PURPOSE: The purpose of this study was to determine if increased body mass index (BMI) is associated with accelerated dental development in children ages 8 to 15. METHODS: The dental development ages of 104 children were determined using the Demirjian method and panoramic radiographs. Using the system developed by the International Obesity Task Force, BMI status was determined for each subject (63 normal weight, 23 overweight, and 18 obese subjects). The difference between chronologic age and dental age was analyzed against BMI, age, and gender using 3-way analysis of variance. RESULTS: Dental development was significantly accelerated with increased BMI, even after adjusting for age and gender (P < .01). The mean difference between chronologic and dental age among all subjects was 0.68 +/- 1.31 years. The mean dental age acceleration for overweight and obese subjects was 1.51 +/- 1.22 years and 1.53 +/- 1.28 years, respectively. CONCLUSIONS: Children who were overweight or obese had accelerated dental development, even after adjusting for age and gender. Accelerated dental development in obese children is an important variable to consider in pediatric dental and orthodontic treatment planning where timing is crucial.
