초록
Paramolar tubercle은 드문 발생학적 치아 기형으로 구치의 협면 또는 설면에서 나타나는 추가적인 교두로 정의된다. 영구치에 융합된 Paramolar tubercle의 존재는 근관치료를 어렵게 하는 원인이 될 수 있다. 그러므로 이러한 변이에 대한 적절한 이해가 성공적인 근관치료를 위해 중요하다. 콘빔 전산화 단층 촬영(CBCT)은 복잡한 증례에서 해부학적 구조를 이해하는 데 도움을 줄 수 있다. 따라서 본 증례는 Paramolar tubercle이 융합된 상악 제2소구치의 비외과적 근관치료에 대한 증례에 대해 보고하고자 한다.
Abstract
Paramolar tubercle is a rare developmental dental anomaly defined as an additional cusp occurring on the buccal or lingual surfaces of the molar. Permanent molar fused with paramolar tubercles can be a cause of difficulty in root canal treatment. Therefore, proper understanding of these variations is important in order to ensure successful endodontic treatment. Cone beam computed tomography (CBCT) can be helpful to understand anatomy of complicated cases. This case report describes nonsurgical endodontic treatment of maxillary second premolar fused with paramolar tubercle.
