Non-surgical treatment of a large periapical lesion: Case report

Abstract

The success of root canal treatment is based on thorough cleaning, shaping, and filling of the root canal system. A non-surgical endodontic treatment was planned because it is the most conservative approach, with continuous monitoring of the lesion at various follow-up periods. The treatment included chemical-mechanical debridement using the crown-apex technique without pressure, followed by filling of the canal with calcium hydroxide for 30 days, which was renewed monthly for a period of four months. Filling was performed using the active lateral condensation technique. Clinical and radiographic follow-up after one year showed total cure of the periapical lesion. This case report shows that the non-surgical conservative approach leads to complete healing of extensive periapical lesions.
