Abstract

The purpose of this clinical report was to show anatomical variations in permanent maxillary second molar using computed tomography (CT). This case report describes the application of CT to detect the unusual root anatomy of maxillary second molar with 2 separate palatal roots for successful endodontic treatment procedures. The use of cone beam computed tomography (CBCT) can overcome the limitation of the periapical standard radiography caused by the overlap of buccal and secondary palatal roots.

이 임상증례의 목적은 상악 제2대구치의 해부학적 형태를 computed tomography (CT)를 이용해 확인하여 근관치료에 활용한 증례이다. 이번 증례에서는 두개의 구개치근을 갖는 상악 제 2대구치에서 성공적인 근관치료를 위해서 CT를 활용하여 해부학적 형태를 확인하여 활용하였다. Cone beam computed tomography (CBCT)의 사용은 구개치근과 협측치근이 겹쳐보이는 치근단 방사선 사진의 한계를 극복할 수 있게 한다.
