摘要 资料和方法:对64例下颌第二磨牙病例的术前X线片、初尖锉片以及根充片进行分析,判断是否为C形根管系统,对初尖锉片进行分类,并与充填片比较。结果:64例下颌第二磨牙中,初始片诊断为C形根管的为28例,占43.8%;初尖锉片诊断为C形根管系统的有34例,占53%;充填片诊断为C形根管的有36例,占56.3%。初尖锉片的X线分型重型10例,Ⅱ型9例,Ⅲ型15例。术后充填片显示有9例表现为根管的融合(Ⅰ型):4例为全C形根管系统;另23例表现为根管的分离(Ⅱ型或Ⅲ型)。没有出现初始片、初尖锉片以及充填片诊断前后不一致的情况。结论:下颌第二磨牙术前片有助于C形根管系统的识别。初尖锉片对C形根管中下段解剖结构的诊断有一定的帮助。
