Nonsurgical Management of Periapical Lesion in Mandibular Incisors with 2 Canals - A Case Report

In-depth knowledge of the root canal system is a major prerequisite for successful endodontic treatment.1 The major aim of endodontic treatment is the eradication of infection and prevention of reinfection in canal. However endodontic treatment may fail because of incomplete knowledge about the anatomical variation of root canals. Most of the times the canal remains untreated because of the inability of the dentist to recognize its presence. For good prognosis of the root canal treatment, proper exploration, complete debridement, biomechanical preparation, and filling of root canal system must be done. Therefore, a dentist must be familiar with all the various possible canal configurations.2 Many times, failure of endodontic treatment may occur because the morphological variation of the tooth unfavourably affects the treatment. Pulpal inflammation can occur as a result of many factors like dental caries or trauma which causes tissue necrosis. Periapical tissue eradication develops in response to microbial accumulation and infiltration of their by-products in the periradicular tissues and activates host's immune reaction.3 The following case report presents the non-surgical management of mandibular central and lateral incisors, with each having two separate canals which join together to form a single canal just before exiting the apical foramen. Before starting root canal treatment, a careful radiographic examination should be done to detect the morphological variations in root canal anatomy. This paper describes two clinical cases of mandibular incisors with or without periapical lesion having two canals.
