초록

목적: 이 후향적 연구의 목적은 한국인에서 콘빔CT를 이용하여 상악 대구치에서 C-형 치근 및 근관의 발현빈도와 형태를 분류하기 위함이다. 연구 재료 및 방법: 총 357개 상악 대구치(제1대구치 186개, 제2대구치 171개)의 콘빔CT 영상을 두 명의 치과보존과 전문의가 평가하였다. 결과: 8가지의 C-형 치근 형태와 5가지의 C-형 근관형태로 분류할 수 있었으며, C-형 치근 및 근관의 발현빈도는 각각 21.0%와 5.3%였다. 결론: 이러한 해부학적 변이는 제1대구치보다 제2대구치에서 많이 발견되었다. 상악 대구치의 성공적인 근관치료를위해 다양한 형태의 C-형 치근 및 C-형 근관에 대한 해부학적 지식이 필요하다.

Abstract

Purpose: The aim of this retrospective study was to investigate the prevalence rate and types of C-shaped roots and C-shaped canal in maxillary molars by analyzing cone-beam computed tomography (CBCT) in a Korean population. Materials and Methods: Total of 357 CBCT images of maxillary molars (186 first molar, 171 second molar) were evaluated by two Endodontic specialists. Results: Eight types of C-shaped roots and 5 types of C-shaped canals were founded, the prevalence rate of C-shaped roots and canals were 21.0% and 5.3% respectively. Conclusion: These anatomical variations were more frequent in second molars than the first molars. Clinicians should have anatomical knowledge about various types of C-shaped root and root canal for successful root canal therapy.
