根据病史、查体、X线检查,我们认为右下唇麻木系(?)“根管治疗”中根充超填侵犯右下齿槽神经所致。而根管充填物无非是固体、糊剂和液剂。根据填物X线阻射影象可排除固体充填物(如牙胶尖、银尖等)超填。而糊剂充填物具有一定的流动性,可造成本例中超填物X线阻射影象。但其流动性是有限的,根疗时其超填物多聚集在根尖部,供讨论病例提及术前X片显示未见明显根尖病变。本病例超填 According to medical history, physical examination, X-ray examination, we believe that the right lower lip numbness (?) “Root canal therapy” in the root filling superfill violation of right lower alveolar nerve caused. The root canal filling is nothing more than solid, paste and liquid. According to the fill ray X-ray image can be excluded solid fillings (such as gutta-percha, silver tip, etc.) over-fill. The paste filling material has a certain mobility, can cause X-ray image of the overlay X ray in this case. However, its mobility is limited, and its root superficial accumulation of more accumulation in the root tip for the discussion of cases referred to preoperative X-ray showed no significant apical lesions. This case is overfilled
