Platelet-Rich Fibrin to Induce Apical Closure in an Immature Multi-Rooted Permanent Tooth with Necrotic Pulp: A Case Report

Regenerative endodontic procedures are the emerging techniques for the restoration of functional pulp and dentine. The case report presented here describes the management of a symptomatic mandibular first molar with an immature apex and necrotic pulp in a 9 year old child. The tooth was tender on percussion and palpation and elicited a negative response to sensibility testing. A regenerative endodontic procedure was performed using triple antibiotic paste as intracanal medicament and platelet-rich fibrin (PRF) as scaffold. Recall visits after 4, 6 and 8 months showed complete resolution of periapical lesion with increased canal wall thickness. The regenerative procedure used induced root development by increasing root wall thickness and closure of apex with regaining of pulp vitality.
