The calcification of the root canal is a process that may occur after a dental trauma or slowly develop due to physiological dental aging. It is characterized by hard tissue deposition on both the pulp chamber and the root canal. Periapical radiography and computed tomography can be used to diagnose this condition. In some cases, it may be associated with pulp necrosis and the presence of periapical injury, and the treatment may be considered to be quite complex. This case report addresses the endodontic treatment of the upper left central incisor, symptomatic, with root canal obliteration and pulp necrosis as a sequela of dental trauma. After all the tests, chronic apical periodontitis was diagnosed, and conventional endodontic treatment was proposed. The most significant difficulty faced was when locating the root canal's entrance. Numerous radiographs were carried out to avoid deviations. The opening of the root canal could only be found at the end of the middle third, só treatment could proceed by using the crown-down technique and intracanal medication based on calcium hydroxide during the sessions. When the patient was asymptomatic, the root canal has been filled. The accomplishment of the technique was successful, and after finishing the case, there was remission of symptoms. After a six-month follow-up period and three years, the healing of the periapical tissues was observed. |
