摘要
目的观察肥胖型儿童骨密度的变化、上气道形态的改变及了解肥胖型儿童饮食、睡眠和口腔疾病既往史。研究肥胖与安氏Ⅱ类错畸形发生的相关性。方法对895例11和12岁儿童进行体重指数(BMI)检查。BMI≥23为肥胖组(n=170);在剩余725例BMI<23的儿童中,随机抽取170例作为配对正常组,对两组儿童进行骨密度检查和统计上气道软、硬组织形态的相关参数。并通过问卷调查了解儿童饮食睡眠和口腔疾病既往史。结果肥胖组骨量减少,上气道相对狭窄,口呼吸习惯及牙体早失几率较高。结论肥胖虽然不是安氏Ⅱ类错畸形发生的直接原因,但与安氏Ⅱ类错畸形发生存在间接相关性。
Objective To observe the changes of bone density and morphology of the upper airway in obese children, and understand their diet and sleep situation and past history of oral diseases, so as to inves- tigate the correlation between obesity and Angel class Ⅱ malocclusion deformity in children. Methods Body mass index (BMI) was examined for 895 children of 11-12 years. The 170 children with BMI ≥ 23 were enrolled into obesity group, 170 children were randomly chosen from the remaining 725 with BMI 〈 23 into matched normal group. Bone mineral density was determined in both groups, and related parameters of soft and hard tissues in upper respiratory tract were calculated. Questionnaire survey was conducted to understand children's diet, sleep and past history of oral diseases. Results In the obesity group, bone mineral density reduced, upper airway was relatively narrow, the incidence of mouth breathing habit and early tooth loss was relatively high. Conclusions Although obesity does not immediately cause Angel class Ⅱ malocclusion, it has an indirect correlation with Angel class Ⅱ malocclusion deformity.
