摘要
C形根管在上颌第一磨牙的发生率极低(0.12%),而釉珠在上颌第一磨牙中的发生率仅为2.68%,同时存在这两种解剖结构的上颌第一磨牙更为罕见。本病例报道1例上颌第一磨牙腭侧(VertucciⅧ型,3-3)融合C形根管伴釉珠的根管再治疗病例,提示利用根管显微镜结合CBCT可发现结构异常并避免遗漏根管。
For maxillary first molar,the incidence of C-shaped root canals was only 0.12%,and the incidence of enamel pearls was 2.68%.Therefore,the presence of both anatomical structures was rarer.Here we report a retreatment case of maxillary first molar with C-shaped palatal root canal(VertucciⅧ,3-3)and furcal enamel pearl.It is suggested that using dental operating microscope combined with CBCT can detect structural abnormalities and avoid missing the root canal.
