The aim of this cross-sectional study was to establish if there is a relationship between body mass index (BMI) and skeletodental development in young obese patients in comparison with normal-weight patients. The sample consisted of 178 individuals (115 normal weight, 37 overweight and 26 obese), aged 6 to 16 years, with a mean biological age of 11.96 ± 2.44 years. Dental maturation (dental age) was determined by using Demerjian's method; craniofacial growth pattern, skeletal and dental class were determined by using cephalometric measurements; skeletal maturation was determined by using Baccetti's method. Data were statistically analyzed. According to Demirjian's method, the mean dental age of the overweight and obese subjects was significantly higher than that of the normal-weight subjects ( = 0.001 and = 0.02, respectively). A higher rate of dental class III was detected in the overweight group ( = 0.002). Concerning cephalometric records, statistically significant differences ( = 0.018) were observed in the distribution of SNA and SNB values, higher values being found in obese subjects. No difference was detected in the distribution of the ANB angle between the groups. As regards craniofacial growth pattern, no significant differences were found between the groups. Children with obesity presented more advanced skeletal maturation, reaching statistically significant differences ( = 0.02), in comparison with the normal-weight subjects. In conclusion, obese children showed increased tooth and skeletal development in comparison to the normal-weight subjects. These findings may be of interest for orthodontists, who should consider weight status when performing orthodontic treatment in children and adolescents.
这项横断面研究的目的是确定与正常体重患者相比，年轻肥胖患者的体重指数（BMI）与骨骼牙齿发育之间是否存在关联。样本包括178名6至16岁的个体（115名正常体重、37名超重和26名肥胖），平均生物年龄为11.96±2.44岁。使用德梅尔坚方法确定牙齿成熟度（牙龄）；使用头影测量法确定颅面生长模式、骨骼和牙齿分类；使用巴切蒂方法确定骨骼成熟度。对数据进行统计学分析。根据德梅尔坚方法，超重和肥胖受试者的平均牙龄显著高于正常体重受试者（分别为P = 0.001和P = 0.02）。在超重组中检测到更高比例的III类错牙合（P = 0.002）。关于头影测量记录，在SNA和SNB值的分布中观察到统计学上的显著差异（P = 0.018），肥胖受试者的值更高。各组之间ANB角的分布没有差异。至于颅面生长模式，各组之间没有发现显著差异。与正常体重受试者相比，肥胖儿童的骨骼成熟度更高，差异具有统计学意义（P = 0.02）。总之，与正常体重受试者相比，肥胖儿童的牙齿和骨骼发育增加。这些发现可能引起正畸医生的兴趣，他们在对儿童和青少年进行正畸治疗时应考虑体重状况。
