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.
