OBJECTIVE
This article discusses the relationship between apical limit of root canal filling and success on endodontic treatment of a mandibular molar.
STUDY DESIGN
A mandibular right first molar with vital pulp was endodontically treated, and 3 years later periapical lesions on mesial and distal roots were detected. The canals were retreated and obturated to the same levels as in the previous treatment.
RESULTS
An 8-year radiographic follow-up showed repair of the periapical lesions on both roots.
CONCLUSIONS
Results suggest that the apical limit of obturation seems to have no influence in the repair of periapical tissues in mandibular molars.
目的
本文探讨根管充填的根尖界限与下颌磨牙根管治疗成功率之间的关系。
研究设计
对一颗牙髓活力正常的右下第一磨牙进行根管治疗，3年后发现近中根和远中根出现根尖周病变。对根管进行再治疗，并充填至与上次治疗相同的水平。
结果
8年的影像学随访显示两根根尖周病变均得到修复。
结论
结果表明，充填的根尖界限似乎对下颌磨牙根尖周组织的修复没有影响。
