PRF in Vital Pulp Therapy: Case Report

Direct pulp capping is a procedure that involves placement of a biocompatible material over an exposed pulp to induce the formation of dentinal bridge to preserve the healthy and functional pulp which is sealed against bacterial penetration. Platlet rich fibrin (PRF) described by Choukroun et al is a second generation platelet concentrate that contains platelets, growth factors and cytokines that enhance the healing potential of both soft and hard tissues. Thus PRF may be considered as an effective pulp capping agent.

To evaluate the clinical and radiographic success of a vital pulp therapy with PRF in a mature permanent molar tooth.

In the current study direct pulp capping (DPC) was performed with platelet rich fibrin (PRF). After clinical and radiographic examination one case with irreversible pulpitis and other case with chronic pulpitis in young patients were selected. Following caries excavation and haemorrhage control the exposure was covered with PRF followed by placing MTA on top of it. The remaining tooth was sealed with a layer of light cure GIC followed by composite resin restoration.

At 1-day follow-up, patient's spontaneous symptoms had resolved. 6-months follow-up demonstrated pulp vitality, clinical function, as well as the absence of pain/tenderness to percussion/palpation/cold sensitivity tests; periapical radiograph showed normal periodontium.

The favourable results indicate that PRF shows promising result in case of pulpal inflammation with irreversible signs and may be a good treatment option in comparison to endodontic treatment.
