Influence of BMI percentile on craniofacial morphology and development in children and adolescents.

摘要: BACKGROUND The prevalence of childhood and adolescent obesity is increasing worldwide. Reports suggest that elevated body mass index (BMI) associated with larger craniofacial dimensions advanced dental skeletal development. Such an association important for timing orthodontic treatment relative to pubertal growth eruption. MATERIALS AND METHODS To evaluate associations between BMI, morphology, age, cervical vertebrae maturation staging (CVMS), 400 participants were consecutively selected (8-15 years, n = 200 overweight obese BMI >85%, normal weight) from the University North Carolina database. Records analysed cephalometric measures, Demirjian values, CVMS. Bivariate statistics linear regression analysis evaluated whether CVMS, varied BMI. RESULTS Overweight/obese children adolescents had a proportionally bimaxillary prognathic pattern compared those weight. These measurements [articulare-gnathion (Ar-Gn), condylion-anterior nasal spine (Co-ANS), sella-gonion (S-Go), nasion-menton (N-Me), anterior spine-menton (ANS-Me), sella-nasion-A point (SNA), sella-nasion-B (SNB), sella-nasion-pogonion (SNPg)] significantly different [statistically (P 2 mm or >2 degrees)] two study groups, relationship percentile dimension. overweight/obese group mean age 1.4 years weight < 0.05), advancement nearly one CVM stage ages 12 14 0.05). LIMITATIONS retrospective. CONCLUSIONS Obese/overweight have antero-posterior vertical are more likely experience maturation. subjects may enter their spurt at younger earlier eruption teeth, affecting timing. should be consideration in growing patients.
