Endodontic Management of Aberrant Root Canal Anatomy in Premolars - A Report of Two Case

A 19-year-old female patient reported to the Department of Conservative Dentistry and Endodontics, with the chief complaint of food lodgment in her upper right and lower left back tooth. There was associated history of mild pain while bitting. Her medical and family history was noncontributory. Intra oral examination revealed a deep carious lesion with respect to the mandibular right second premolar (45) and maxillary left first premolar (24). On evaluation of the pulp status, both the teeth showed no response with heat (gutta-percha stick), cold (ice piece) and electric pulp testing (Parkell Electronics Division, Farmingdale, NY). The teeth were tender to percussion suggestive of symptomatic apical periodontitis. Intraoral periapical radiograph (IOPA) in relation to 45 and 24 revealed deep proximal caries involving the pulp (Figure 1). There was also widening of periodontal ligament space confirming the diagnosis of apical periodontitis in both the teeth. Root canal treatment for 45 and 24 was planned out. Intraoral periapical radiographs revealed Introduction
