联合翻瓣术治疗下颌第二磨牙远中邻面龈下龋坏

Combined Use Flap Operation to Cure Distal Surface Subgingival Caries of Mandibular Second Molar

目的:探讨联合翻瓣术治疗下颌第二磨牙远中邻面龈下龋坏的疗效。方法:收集下颌第二磨牙远中邻面龈下龋坏13例患者共15颗患牙在锥形束CT引导下行切开翻瓣暴露、去龋、充填,同期对不良牙周组织形态进行纠正。术后经影像学观测充填情况,分别于1、3、6后检查充填及牙周情况。结果:13例患牙影像学上观测充填严密,经1、3、6个月观察充填体无脱落,无继发龋,无牙龈探诊出血,牙周袋深度≤3mm,成功率为87%。结论:联合翻瓣术治疗下颌第二磨牙远中邻面龈下龋坏的方法是值得推广。

Objective：To explore the effect of distal surface subgingival caries of mandibular second molar treated by flap operation.Methods：13patients who have 15teeth which are distal surface subgingival caries of mandibular second molar.We are guided by cone-beam computed tomography（CBCT）adopting distal flap operation to exposure operative region,then to remove the caries and then to fill the cavity and to correct the bad periodontal tissue.After1,3,6months,filler material circumstance,PD,BOP were examined.Results：After 1,3,6months observation,we find the filler materials without shedding,no secondary caries,PD≤3mm,BOP（-）.Success rate is 87 percent.Conclusion：Distal flap operation for clinical treatmentcan be used to cure distal surface subgingival caries of mandibular second molar.
