Variations in root number and canal morphology are challenges for successful endodontic therapy. This report describes 2 endodontically managed maxillary first molars with asymmetric presentation of unusual palatal root morphology. These included the left maxillary first molar with a single palatal root and 2 palatal canals and the right maxillary first molar with 2 separate palatal roots with 1 canal in each root. An accurate diagnosis was confirmed with the help of spiral computerized tomography. This case report discusses this asymmetric variation in the palatal root morphology and highlights the value of spiral computerized tomography in diagnosis of such unusual cases.
牙根数量和根管形态的变异是成功进行牙髓治疗的挑战。本报告描述了2例牙髓治疗的上颌第一磨牙，其腭根形态异常呈不对称表现。其中包括左侧上颌第一磨牙有1个腭根和2个腭根管，以及右侧上颌第一磨牙有2个独立的腭根，每个根有1个根管。借助螺旋计算机断层扫描确诊。本病例报告讨论了腭根形态的这种不对称变异，并强调了螺旋计算机断层扫描在诊断此类罕见病例中的价值。
