摘要
上颌第二磨牙(MSM)牙根及根管系统的数目、形态均变异较大,牙根融合和颊侧第二根管是常见的变异。本文报告1例罕见的MSM解剖变异,经锥形束计算机体层扫描证实为单牙根,双腭管,且4个根管在根尖区融合为1个根管。
The roots and roots canal system vary greatly in the maxillary second molars(MSMs),where root fusion and the second mesiobuccal canal(MB2)are common variations.This case reported a rare anatomical variation of MSMs,confirmed by cone beam computed tomography(CBCT),which was one single conical root,2 palatal canals and 4 canals fused into one at the apical region.
