摘要：

背景：熟悉根管解剖形态，了解其弯曲程度，可以在一定程度上预防根管预备时的并发症，提高根管治疗的成功率。
目的：了解山东地区汉族人恒前牙根管弯曲的情况。
方法：采用间接数字化X射线成像技术，对收集的离体208颗前牙进行颊舌向和近远中向拍摄，采用改良的Schneider测量方法，分析根管弯曲情况。
结果与结论：山东地区汉族人前牙根管多为Ⅰ型根管，且半数以上存在弯曲，弯曲部位多集中在根尖1/3，尤以上颌尖牙根管弯曲发生率最高，除上颌中切牙外，其余牙位均有S形弯曲根管，下颌前牙在唇舌方向上弯曲半径明显高于近远中方向。提示山东地区汉族人恒前牙根管形态复杂，弯曲率较高。

Abstract:

BACKGROUND: It can to a certain extent prevent complications during root canal preparation and improve the success rate of root canal therapy by understanding root canal anatomical configuration and bending degree.
OBJECTIVE: To investigate the root canal curvature of permanent anterior teeth from Han Chinese people in Shandong province.
METHODS: A total of 208 anterior teeth were collected and examined by indirect digital X-ray radiography both from labiolingual and mesiodistal directions, according to Schneider method, the data obtained were analyzed.
RESULTS AND CONCLUSION: Most root canals of anterior teeth from Shandong province were typeⅠ, and more than half were curved. The most curvature happened in the apical third. The highest rate of canal curvature occurred in maxillary canines. Except the central incisors, the S-shaped canal was observed on the rest teeth. The radius of mandibular anteriors was obvious longer in labiolingual directions than that in mesiodistal directions. Root canal curvatures of anterior teeth from Shandong province are complex and have a higher bending rate.
