Non-surgical treatment of extensive periapical lesion with repair of periapical bone radiolucency - One-year control

Abstract

This study reported the repair of an extensive circumscribed periapical lesion with a diagnosis suggestive of chronic periapical periodontitis. A 46-year-old male patient was referred to an endodontist for endodontic treatment on the right upper lateral incisor. Clinically, he is asymptomatic, with a negative response to the cold pulp sensitivity test carried out with refrigerant gas. After anesthesia, the coronal opening and cervical and middle root canal preparation were performed with the Reciproc Blue R#40 file. The working length was determined with an apex locator, followed by irrigation with 2.5% sodium hypochlorite. The apical preparation was performed with the Reciproc Blue R#50 system, and the foraminal patency was made with the Glide 35.01 file in the apical foramen. The filling of the canal system was performed using the single cone technique, associated with Bio-C Sealer cement.  Clinical and radiographic follow-up was carried out six months and one year after root canal filling, showing repair of the periapical bone radiolucency. It is concluded that the success of endodontic therapy is achieved when the diagnosis, sanitation of the canal system and an airtight filling are carried out correctly, as well as the definitive sealing of the coronary access.
