Root canal treatment of a maxillary central incisor with two root canals: A case report

Abstract

The aim of the present study is to report a clinical case of a root canal treatment of a maxillary central incisor with two root canals. The clinical examination showed a discrete increase in the crown width of tooth 11, which responded negatively to ice sensitivity, percussion and palpation tests. The tomographic examination of tooth 11 revealed the presence of two root canals and bone rarefaction in the periapical region, thus suggesting a possible pulp necrosis and asymptomatic apical periodontitis. Local anesthesia and proper isolation were performed, followed by coronal access to the pulp chamber with the aid of an operating microscope. The working length was established at 21 mm in the distal portion and 20 mm in the mesial portion of the tooth. The root canals were mechanically prepared with the Wave OneR system and obturated using the hybrid thermo-mechanical technique and AH PlusR sealer. The patient remained asymptomatic during the 12-month follow-up period, which suggests that the therapeutic protocol was adequate and the treatment was successful.
