Non-surgical management of a large periapical lesion with internal resorption using PRF, hydroxyapatite and MTA

Abstract

Periapical lesions of endodontic origin are caused by microbial infection of pulp. According to various studies, it is known that necrosis of pulp provides a favourable habitat for microbes to replicate and release various toxins into the periapical tissue leading to inflammation and formation of a periapical lesion. A variety of non-invasive methods to manage such lesions include conservative root canal treatment, aspiration-irrigation technique, decompression technique, calcium hydroxide therapy, lesion sterilisation and tissue repair therapy, and the apexum procedure. We present a case report describing non-surgical management of a large periapical lesion associated with a permanent central incisor displaying internal inflammatory resorption using platelet rich fibrin (PRF), bone graft and mineral trioxide aggregate (MTA).
