Abstract
본 연구의 목적은 특이한 C형 치근과 근관을 가지고 있는 상악 제 1대구치의 근관치료 증례를 콘빔단층촬영을 사용하여 진단 및
치료하였음을 보고하는 것이다. 본 증례에서는 특이적인 해부학적 근관 형태가 콘빔단층촬영을 사용하여 확인되었으며 비외과적 근관치료가 시행되었다. 촬영한 영상에서 모든 치근이 C 형태로 융합되어 있으며 독립적인 4개의 근관을 포함하고 있음이 관찰되었다. C형 근관계의 복잡성을 고려할 때 콘빔단층촬영이 적절한 근관계의 확인과 의원성 손상을 예방하기 위해 유용한 보조적 방법인 것으로 보여진다.
The presence of untreated canals is a wellknown cause of endodontic failure after treatment1). Hence, for a successful endodontic treatment, a thorough understanding of the root canal morphology is very important. During the clinical procedure, however, unexpected anatomic variations can be encountered, one of which is a C-shaped root canal usually found in the mandibular second molars. This morphological variation also has been reported to be in the maxillary first molars, with the reported incidence of this rare anatomy being as low as 0.09%. With developing armamentarium such as conebeam computed tomography (CBCT) and dental operative microscope (DOM), they became a valuable tool for canal identification, especially in complex canal morphology.
This report describes a rare C-shaped variation in a maxillary first molar which was identified by CBCT and treated by non-surgical root canal treatment.
