Abstract
To achieve success in endodontic treatment, it is essential to have a thorough understanding of the root and canal morphology. While maxillary canines typically have a single root and canal, studies have reported variations in different populations. This case report details the non-surgical endodontic management of a maxillary canine (tooth no. 13) with a Vertucci type 3 canal configuration in a 69-year-old female patient. The patient reported pain in the maxillary right canine (#tooth no. 13) and was diagnosed clinically with apical periodontitis. The patient's dental history revealed an ameloblastoma in the right mandibular region, successfully treated five years ago. Cone beam computed tomography aided the treatment. After completing the root canal treatment (#13) involving the two canals, an incidental loop-type accessory canal was noted. After three years of follow-up, the patient reported being asymptomatic. This paper reports the endodontic management of an uncommon type 3 canal configuration in the maxillary canine. Clinicians must remain aware of canal variations and utilize modern diagnostic tools like cone beam computed tomography to ensure all canals are located and adequately treated.
