Evaluation of Periapical Healing of Apicomarginal Defect in Mandibular First Molar Treated with Platelet Rich Fibrin: A Case Report.

The presence of an apicomarginal defect is one of the reasons for the failure of endodontic treatment. The best treatment option to treat an apicomarginal defect is to perform endodontic surgery using Guided Tissue Regeneration (GTR) membranes. The present case report evaluated the healing of periapical lesion along with apicomarginal defect using Platelet Rich Fibrin (PRF) as membrane in periapical surgery of mandibular first molar. Recall examination was performed at 3 and 18 months post surgery. A satisfactory periapical healing was evident using PRF in apicomarginal defect of mandibular first molar. PRF may be considered as an alternative treatment for GTR membranes in the treatment of apicomarginal defects.
