Nonsurgical re-treatment of a twin-rooted maxillary lateral incisor

[摘要] An accurate diagnosis of the anatomy of the root canal system is a prerequisite for successful endodontic treatment. Morphological variations or additional roots/root canal should always be expected. These variations should be strongly considered before starting any endodontic treatment using various diagnostic aids for better outcome therapy. Nonsurgical endodontic re-treatment of a painful twin-rooted maxillary lateral incisor tooth of a 40-year-old female was carried out due to improper diagnosis of the extra root. The clinical examination and radiographic analysis confirmed the diagnosis of previously treated/necrotic pulp and symptomatic apical periodontitis. The patient remained asymptomatic at 6-month follow-up both clinically and radiographically. The case report emphasized on the need for clinicians to be extra careful while treating such teeth and use of cone-beam computed tomography for their diagnosis and management.
