摘　　要：目的探讨中国成人离体上前牙牙体和髓腔根管解剖对根管治疗难度的影响,为根管治疗难度系数评估标准的临床应用奠定基础。方法对80颗牙体完整、解剖标志清楚的中国成人离体上前牙使用放射影像学等方面获取评估的解剖资料,采用根管治疗难度系数评估标准评估其对根管治疗难度的影响。结果根管治疗难度系数评估标准利用牙体和髓腔根管解剖能进行根管治疗难度的评估。影响根管治疗难度的主要因素为:中切牙为根管弯曲、侧切牙为根管弯曲和钙化、尖牙为过长牙。结论根管治疗难度系数评估标准在评估分析中操作规范、直观简便、科学有效,但需在临床上进一步研究。Objective To study the practicability of the Endodontic case difficulty assessment standards which applied to Chinese permanent maxillary anterior teeth.Methods 80 maxillary anterior teeth including 27 maxillary central incisors 22 maxillary lateral incisors and 31 maxillary canines were fabricated and each X-rayed in the directions of labiopalatine projection,all the teeth were rated systematically with specific risk factors of assessment standards about root canal therapy.Results Endodontic case difficulty assessment standard could be applied to evaluate the root canal treatment difficulty score based on the anatomy of tooth.The major risk factors were root canal curvature in maxillary central incisor,root canal curvature and calcification in maxillary lateral incisors,and supra length in maxillary canines,respectively.Conclusion The Endodontic case difficulty assessment standards demonstrated standard,simple and convenient,scientific and effective.Clinical study was further needed.
