Conservative Endodontic Treatment Of A Large Periapical Lesion

Abstract

A 60-year-old female presented with a large periapical radiolucency associated with a previously root filled 1.3 and suspected involvement of the 1.2. Endodontic treatment of 1.2 had been commenced by the referring dentist. Following a differential diagnosis, conservative endodontic treatment was instituted. A post was removed from 1.3 and long term calcium hydroxide intracanal dressings placed in both teeth. The lesion showed good repair over a period of 12 months. This case report supports the view that the treatment of choice for periapical lesions associated with failed conventional endodontic treatment is orthograde re-treatment with regular follow-up to confirm bony healing.
