37例恒前牙水平根折保守治疗的回顾研究

A retrospective study of conservative management of 37 permanent incisors with horizontal root fracture

目的:观察保守疗法治疗恒前牙水平根折的预后及其影响因素。方法:选择恒前牙水平根折保守治疗且随访3个月以上的病例30份,分析其愈合率,并依据根折部位、牙根发育情况、就诊间隔时间、固定时间分组,分析其与愈合相关的因素。结果:30份病例共有患牙37个,随访时间3~34个月。其中愈合33个,愈合率89.19%。根折部位、牙根发育情况、就诊间隔时间及固定时间对其愈合率的影响无统计学差异(P>0.05)。结论:恒前牙水平根折保守治疗的预后较好,根折的部位、牙根发育情况、就诊间隔时间及固定时间与根折愈合率无相关性。

AIM： To observe the effects of conservative treatment on the prognosis of horizontal root fracture of permanent incisors and the influencing factors. METHODS： 37 permanent incisors with horizontal root fracture in 30 patients were treated by conservative therapy and followed-up for 3 to 34 m. The healing rate was calculated and the influencing factors of prognosis were analyzed based on the data of fracture location,root development,treatment delay and fixation time. RESULTS： 33 teeth（89. 19%） exhibited healing of the root fractures. Fracture location,root development,treatment delay and fixation term were not found to be related to the rate of healing. CONCLUSION： The prognosis of conservative therapy for permanent incisors with horizontal root fracture is good. Fracture location,root development,treatment delay and fixation term are not related to the healing rate.
