However, the complex variations of root canal system often affect the effect of root canal treatment and even lead to treatment failure. Therefore, it is of great significance for dentists to emphasize the diversity of root canal morphology and to be familiar with the anatomical morphology of root canal to improve the success rate of clinical diagnosis and treatment. We reported a case of an eight-year-old female patient of type V root canal in a young maxillary middle incisor. The young maxillary central incisor was diagnosed with irreversible pulpitis by radiography and CBCT examination. The present case report described the entire treatment procedure of a young maxillary central incisor after trauma, including successive apical examination, CBCT examination and multiple root canal filling, and finally the treatment was completed with the aid of microscope. The root canals were filled with the vertical compression technique. Z350 composite resin was used to repair the tooth. The patient was followed-up at three, six, and 12 months after endodontic treatment. All of the examinations were normal. Finding the anatomical configuration of root canal by various ways will help to improve the success rate of root canal therapy.Keywords: cone-beam computed tomography, CBCT, one root with two root canals, root canal microscope, young maxillary central incisor
