Non-surgical management of a large periapical lesion in relation to a mandibular second molar and concomitant external root resorption of the mandibular first molar

Abstract

Periapical lesions associated with endodontically treated teeth can be managed by nonsurgical retreatment, periapical surgery, or extraction. Various demerits of periapical surgery favor a nonsurgical retreatment approach. This case report presents the nonsurgical management of a large periapical lesion in relation to a mandibular second molar along with concomitant external root resorption of the mandibular first molar. Aspiration of fluid from the periapical lesion was carried out through the root canals of tooth #37, followed by calcium hydroxide therapy. The external root resorption in relation to the distal root of tooth #36 was managed with calcium hydroxide therapy. The follow-up radiographs revealed progressive healing of the periapical lesion and restoration of the root architecture of the distal root of tooth #36. This case report highlights that large periapical lesions in relation to mandibular molars can heal nonsurgically. first molar. Int J Med Dent Case Rep 2021;7:1-3.
