The aim of endodontic treatment is to eliminate infection from the root canal by cleaning and shaping. Multiple factors, such as a broken instrument or anatomical variations in root canals, lead to treatment failure. This article describes a mandibular canine with two canals and two foramina. It is presented here to raise awareness of the importance of an improved access cavity in detecting excess canals.
根管治疗的目的是通过清洁和塑形来消除根管内的感染。多种因素，如器械折断或根管解剖变异，会导致治疗失败。本文描述了一例具有两个根管和两个根尖孔的下颌尖牙。在此展示该病例是为了提高人们对改良开髓腔在检测额外根管方面重要性的认识。
