Use of CBCT to Determine Morphological Differences of Mandibular Incisor Root Canal Anatomy: A Modified Classification System
Abstract
Successful endodontic treatment is a multi-factorial process reliant on proper diagnosis, knowledge of morphology, access design, cleaning, shaping, adequate obturation and host response. The focus of this paper will be the knowledge and intricacies of morphology and access of mandibular incisors. Not knowing what to expect, or look for, when accessing a tooth can lead to missed canals, uninstrumented canal space, and inadequate obturation. On average, at least 35% of the canal surface area remains untouched with Ni-Ti preparations (1). This number becomes even higher when the canal was oval or flattened. Paque et al observed 60 to80% untouched dentinal walls when the canal is oval shaped (2). Other studies have shown that uninstrumented canal surfaces will not be cleaned and disinfected as expected by conventional irrigation methods with Sodium Hypochlorite (3, 4, 5, 6). This is problematic, considering that persistent intraradicular infection is the most common cause of post-treatment apical periodontitis (7).
