| 摘 要： | 目的:了解下颌第二恒磨牙"C"形根管的发生情况,为提高根管治疗的治疗效果提供解剖学依据。方法:选取80例离体下颌第二恒磨牙和130例临床上需进行根管治疗的下颌第二恒磨牙,对根管进行探查并结合X线技术,以确定"C"形根管发生情况。结果:80例离体下颌第二恒磨牙中"C"形根管31例,发生率为38.75%。130例临床上需进行根管治疗的下颌第二恒磨牙中"C"形根管为33例,发现率为25.38%。结论:下颌第二恒磨牙根管形态复杂,"C"形根管发生率高,充分了解其根管解剖对提高根管治疗效果有重要意义。

| Abstract: | Objective To observe the C-shaped root canal of mandibular second molars so as to provide anatomical evidence for root canal therapy.Methods A total of 210 well-developed mandibular second molars were examined to make sure the number of the C-shaped root canal.Results C-shaped root canal was found in 31 teeth in vitro(38.75%) and in 33 teeth in vivo(25.38%).Conclusion The root canal systems of mandibular second molars vary considerably in their anatomical configuration,and C-form of root canal presence increases the difficulty of treatment,so it is very important to master the root canal knowledge for the success of root canal therapy. |
