Mineral trioxide aggregate apexification: A novel approach

Abstract

The treatment of choice for necrotic teeth with immature root is apexification, which is induction of apical closure to produce more favorable conditions for conventional root canal filling. The most commonly advocated medicament is calcium hydroxide although recently considerable interest has been expressed in the use of mineral trioxide aggregate (MTA). MTA offers the option of a two-visit apexification procedure so that the fragile tooth can be restored immediately. However, difficulty in placing the material in the wide apical area requires the use of an apical matrix. Materials such as collagen, calcium sulfate, and hydroxyapatite have been used for this purpose. This article describes the use of resorbable suture material to form the apical matrix which offers many advantages over the contemporary materials.

Single-Visit Apexification of Immature Necrotic Permanent Teeth with the use of Mineral Trioxide Aggregate: A Case Series

“…[11] A bonded restoration can then be placed without any delay, thus reducing the possibility of root fractures. [3] The clinical success of MTA for one-visit apexification procedure has been reported by many authors in the literature.…”

“…The treatment of choice in such cases is apexification, i.e., establishing an apical barrier. [3] Apexification can be defined as a 'method to induce a calcified barrier in a root with an open apex or the continued apical development of teeth with incomplete roots and a necrotic pulp' (American Association of Endodontists 2003). Traditionally, calcium hydroxide Ca(OH) 2 has been widely used for the apexification procedure due to its biological and healing performances.…”

“…[6,7] The traditional use of Ca(OH) 2 is being gradually replaced by mineral trioxide aggregate (MTA) as a onestep apexification technique. [8,9] MTA produces apical physical barrier with significantly greater consistency than calcium hydroxide. [10] A biocompatible material, MTA also helps in the formation of bone and periodontium around its interface.…”

Apexification: A systematic review

“…[ 4 5 ] The traditional use of Ca(OH) 2 to achieve apexification is being gradually replaced by mineral trioxide aggregate (MTA) as a one-step technique. [ 6 7 ] The MTA can be placed as an apical plug with previous applications intracanal with Ca(OH) 2 to produce the disinfection of the same[ 8 ] or even the MTA can be used as a material of canal filling. [ 9 ]…”

Management of an Open Apex and Periapical Lesion With Mta and Restoring the Bony Defect With Bone Graft Material and PRF- A Case Report

“…With the advent of bioactive materials like MTA, earlier concepts to achieve apexification by traditional use of Ca (OH)2 is replaced as a one-step technique. 3 Surgical endodontics is a method opted for the treatment of teeth with periapical lesions which do not respond to conventional root canal treatment. 4 Apical surgery includes incision and drainage, closure of perforations, and root or tooth resections.…”
