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.
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.
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.
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.
本研究旨在确定体重指数（BMI）升高是否与8至15岁儿童的牙齿发育加速有关。
采用德米尔坚方法和全景X线片确定104名儿童的牙齿发育年龄。使用国际肥胖特别工作组开发的系统，确定每个受试者的BMI状态（63名正常体重、23名超重和18名肥胖受试者）。使用三因素方差分析，分析实际年龄与牙齿年龄之间的差异与BMI、年龄和性别的关系。
即使在调整年龄和性别后，随着BMI升高，牙齿发育仍显著加速（P <.01）。所有受试者实际年龄与牙齿年龄的平均差异为0.68±1.31岁。超重和肥胖受试者的平均牙齿年龄加速分别为1.51±1.22岁和1.53±1.28岁。
即使在调整年龄和性别后，超重或肥胖儿童的牙齿发育仍加速。在时机至关重要的儿童牙科和正畸治疗计划中，肥胖儿童牙齿发育加速是一个需要考虑的重要变量。
