Article history: The aim of the present study is to report a clinical case of a root canal treatment of a max-
Received 13 May 2019 illary central incisor with two root canals. The clinical examination showed a discrete in-
Accepted 7 September 2019 crease in the crown width of tooth 11, which responded negatively to ice sensitivity, per-
Available online 30 September 2019 cussion 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
Keywords: pulp necrosis and asymptomatic apical periodontitis. Local anesthesia and proper isolation
Cone-beam computed tomography were performed, followed by coronal access to the pulp chamber with the aid of an oper-
Dental pulp cavity ating microscope. The working length was established at 21 mm in the distal portion and
Endodontics 20 mm in the mesial portion of the tooth. The root canals were mechanically prepared with

Incisor the Wave One system and obturated using the hybrid thermo-mechanical technique and
®
Root canal therapy AH Plus sealer. The patient remained asymptomatic during the 12-month follow-up peri-
od, which suggests that the therapeutic protocol was adequate and the treatment was
successful. (Rev Port Estomatol Med Dent Cir Maxilofac. 2019;60(3):145-149)
