Anatomical variations in root canal morphology are an enigma and it is this variability, which is often a complicating factor in a successful root canal treatment. To achieve success in endodontic therapy it is imperative that all the canals are located, cleaned and shaped and obturated three dimensionally. Maxillary first premolar having three separate roots has an incidence of 0.5-6%. Even rarer are reported clinical case reports of maxillary second premolar with three separate roots and three canals. This case report describes the endodontic management of maxillary second premolar with two palatal roots and one buccal root having three root canals.
根管形态的解剖变异是一个谜,正是这种变异性常常成为成功进行根管治疗的一个复杂因素。为了在牙髓治疗中取得成功,必须找到所有根管,进行清理、塑形并进行三维充填。上颌第一前磨牙有三根独立牙根的发生率为0.5%-6%。上颌第二前磨牙有三根独立牙根和三个根管的临床病例报告则更为罕见。本病例报告描述了对上颌第二前磨牙的牙髓治疗,该牙有两个腭根和一个颊根,共有三个根管。
