Evaluation of healing with use of an internal matrix to repair furcation perforations

Abstract

Within this animal model healing responses are better when an internal matrix, whether HAPSET or hydroxyapatite, is used in the repair of furcation perforations.

Mineral Trioxide Aggregate as Repair Material for Furcal Perforation: Case Series

“…In cases of teeth with large-size furcal perforation, the repair material can extrude into the interradicular area, triggering tissue inflammation and foreign body reaction (17,18). The use of biocompatible material has been advocated to avoid extrusions and the ensuing complications (18,19).…”

Management of a Traumatized Open Apex Tooth with a Combination of Mineral Trioxide Aggregate Apical Plug and Platelet-rich Fibrin Apical Matrix

“…Several other materials have also been recommended to create a matrix in cases of perforations as well as teeth with incomplete formation of apex, which include CH, hydroxyapatite, resorbable collagen, calcium sulphate, platelet-rich fibrin (PRF), freeze dried bone allograft and tricalcium phosphate. [9][10][11][12] Platelet-rich fibrin developed in France by Choukroun and Dohan represents a new step in the platelet gel therapeutic concept. Platelet-rich fibrin is a matrix of autologous fibrin embedded with a large quantity of platelet and leukocyte cytokines during centrifugation.…”

Apexification of Immature Teeth Using Novel Apical Matrices and MTA Barrier: Report of Two Cases

“…The use of a matrix is advisable since its placement in the area of bone destruction provides a base on which the sealing material, especially MTA, can be placed and packed in the perforation [10][11][12][13] Several materials have been recommended to create a matrix, in cases of perforations as well as teeth with incomplete formation of apex; including calcium hydroxide, hydroxyapatite, resorbable collagen and calcium sulfate [11][12][13][14][15][16]. Materials such as Platelet rich fibrin (PRF), DFDBA (dimeralised freeze dried bone allograft) are widely used as graft material in periodontal and oral surgical procedures but not reported in literature to be used as apical matrix.…”
