Periosteum-Assisted Coronally Repositioned Flap with EDTA Root Biomodification: A Case Report

The periosteum, a vascular connective tissue layer covering the bone, has great regenerative potential, making it suitable for use in autogenous grafts.The periosteal eversion technique utilizes the periosteum to cover exposed tooth roots.This case report focused on evaluating root coverage using this method for a patient with Miller's Class II recession on a maxillary canine.A partial-thickness flap was reflected, root biomodification was performed using EDTA, and the periosteum was everted over the exposed root and sutured.After six months, 90% of the root surface was successfully covered, highlighting the technique's effectiveness for gingival recession treatment.
