Abstract
Successful Alliance of MTA and PRF for Treating Young Permanent Tooth: A Case Report
Highlights
Young permanent teeth with pulpal necrosis require an artificial material to induce the closure of an open apex as the root development ceases
Platelet rich fibrin (PRF) which is a second generation platelet concentrate can be used as a resorbable matrix material against which Mineral Trioxide Aggregate (MTA) apical barrier can be placed
Calcium hydroxide has been the material of choice for apexification and few studies have shown a 100% success rate with it but previous literature states that Calcium Hydroxide can cause radicular dentin fracture when in contact with it for a long time [8]
Summary
Young permanent teeth with pulpal necrosis require an artificial material to induce the closure of an open apex as the root development ceases. Lemon [4] introduced the “internal matrix concept” which involved the placement of hydroxyl apatite through the perforation to form an external barrier and matrix, against which the perforation repair material (amalgam) was condensed. He recommended the use of a matrix when the diameter of the perforation is larger than 1mm to prevent the extrusion of sealing material. It is added to surgical wounds which are in need of supported or accelerated healing This case report describes the management of a necrosed young permanent tooth with open apex using MTA for apexification and PRF as an internal matrix
