摘　　要：目的:比较研究牙周炎患者和牙周健康患者在正畸治疗的排齐整平阶段牙根吸收的情况。方法:选择成年错畸形患者60例,轻度牙周炎患者和牙周健康者各30例,均不需拔牙,MBT直丝弓固定矫治,排挤整平过程中不同时间点:0个月(T0)、1个月(T1)、6个月(T2),分别拍摄两组病例上下前牙的数字化平行定位投照根尖片,统计各牙不同时期的牙根长度X0、X1、X2,及牙根吸收量X(0-1)和X(0-2)。结果:实验组和对照组在T1和T2期,均发生很轻微的牙根吸收,但两组间不同时间点牙根吸收量X(0-2)、X(0-1),差异无统计学意义。结论:MBT正畸治疗的不拔牙病例排齐整平阶段中,牙周炎患者和牙周健康患者均会发生很轻微(都小于1mm)牙根吸收,但二者之间牙根吸收量无差异。Objective：To compare the external apical root resorption of patients with and without periodontitis during the alignment and leveling phase of orthodontic treatment.Methods：60adults malocclusion patients were chosen,30 were periodontal disease,and 30 were not,All did not need extraction and used MBT technique.The magnitude of EARR were detected by using digital paralleling technique.The films were obtained before the orthodontic treatment（T0）,1（T1）and 6（T2）months after the orthodontic treatment.We compared the magnitude of EARR in different phases between the two groups.Results：EARR occurred in both groups during the alignment and leveling phase,but there was no statistical difference in the magnitude of EARR X（0-2）,X（0-1）between the two groups.Conclusion：EARR occurred in both groups,however,the difference was not significant.
