成年人正畸治疗中上前牙牙根吸收的CBCT研究
Study of CBCT for Root Resorption of the Anterior Teeth of Maxillary During Adult Orthodontic Treatment
摘要
Abstract
To evaluate the correlations between root resorption during orthodontic treatment using cone-beam computed tomography(CBCT).Method:10 patients who treated for orthodontic tooth were selected, and measured the root resorption around six teeth(bilateral maxillary central incisors,lateral incisors,and canines) by using CBCT,before orthodontic treatment and after 12 months treatment,the correlation was calculated between root resorption.Result:The length of all measuring tooth root were compared before and after treatment,and the differences were statistically significant(P<0.05). The root resorption was largest in the maxillary lateral incisors, the left and right lateral incisors were 1.13 mm and 1.14 mm respectively;followed by the maxillary central incisors, the left and right central incisors were 0.97 mm and 0.96 mm;and then was the maxillary canines,the left and right canines were 0.87 mm and 0.95 mm.Conclusion:(1)The patients have an obvious root absorption in the treatment of orthodontic tooth orthodontic.(2)This study has demonstrated that CBCT is a useful approach for evaluating apical root resorption after orthodontic treatment.关键词
