Rangoonwala Dental College, with a chief complaint of a discolored maxillary right central incisor. This article presents a detailed case report of the use of such a matrix prior to placement of MTA as an apical barrier.Īn 18-year-old male patient reported to the Department of Conservative Dentistry and Endodontics, M.A. The use of calcium sulfate or calcium sulfate hemihydrate in combination with collagen has been recommended as a barrier in a number of studies. ,, ,, 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.
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. Lemon advocated the use of a matrix when the perforation diameter is larger than 1 mm to avoid extrusion of the sealing material. The authors also concluded that the chances for biological calcific bridge formation are favorable when the root canal apices are flush or underfilled with MTA. MTA has shown to be effective in performing the same procedure in a considerably lesser period of time with predictable results. , A study comparing the effectiveness of calcium hydroxide versus MTA has shown that this material has been found to be as effective as calcium hydroxide (Ca(OH) 2 ) for the treatment of cases with an open apex. ,, ,, It has been used for procedures ranging from direct pulp capping to perforation repair as well as for inducing an artificial barrier in open-apex cases (apexification).
Recently, mineral trioxide aggregate (MTA) has been popularized in endodontics due to a large amount of research indicating the beneficial properties of the material in terms of bio-compatibility, ease of manipulation and placement, and a wide array of applications.

The technique also demonstrates the use of a delivery system utilizing large-bore needles for the predictable and precise placement of the barrier materials at the apex of the tooth.
