Maxillary Second Molar with Five Root Canals and a Root-Like Enamel Pearl: A Rare Case Report

Permanent maxillary second molars' root canal treatment due to their root configurations complexity and high root canal systems variations, are one of the most problematic teeth. Accordingly, clinicians should consider unusual canal morphology to reduce the rate of missed canals. A thirty-year-old female was referred for root canal treatment of her maxillary right second molar tooth with obvious recurrent caries under restoration and necrotic pulp. Pre-operative radiographs showed the unusual morphology and cone-beam computed tomography was ordered for precise evaluation of the root canal anatomy. The principal aim of this paper is to report a five-root canals maxillary second molar, with two palatal root canals and a palatal root-like enamel pearl canal.
