Osteoblast biocompatibility of mineral trioxide aggregate

Biomaterials, 1999
This study investigated the biocompatibility of variants of mineral trioxide aggregate (MTA), by culturing human MG63 osteosarcoma cells in the presence of materials, observing cytomorphology and cell growth, and then assaying cytokine expression from the cells. Reference materials were employed.

Hydration mechanisms of mineral trioxide aggregate

International Endodontic Journal, 2007
AbstractAim  To report the hydration mechanism of white mineral trioxide aggregate (White MTA, Dentsply, Tulsa Dental Products, Tulsa, OK, USA).Methodology  The chemical constitution of white MTA was studied by viewing the powder in polished sections under the scanning electron microscope (SEM). The hydration of both white MTA and white Portland cement

Vital pulp therapy with mineral trioxide aggregate

Dental Traumatology, 2005
Abstract –  The present case report describes the treatment of complicated crown fractures using mineral trioxide aggregate (MTA). MTA was used as pulp‐capping material after partial pulpotomy to preserve the vitality of the pulpal tissues in two cases.

Color stability of white mineral trioxide aggregate

Clinical Oral Investigations, 2012
This study aims to evaluate the color stability of white mineral trioxide aggregate (WMTA) after irradiation with three different curing lights and with a fluorescent lamp in an oxygen-free environment.Thirty samples of WMTA were divided into four experimental groups (three curing light and one fluorescent lamp) and one negative control group.

MINERAL TRIOXIDE AGGREGATE: A NEW MATERIAL FOR ENDODONTICS

The Journal of the American Dental Association, 1999
Mineral trioxide aggregate, or MTA, is a new material developed for endodontics that appears to be a significant improvement over other materials for procedures in bone. It is the first restorative material that consistently allows for the overgrowth of cementum, and it may facilitate the regeneration of the periodontal ligament.The authors present ...

Evaluation of Antifungal Activity of Mineral Trioxide Aggregate

Journal of Endodontics, 2003
The purpose of this investigation was to study, in vitro, the antifungal effect of mineral trioxide aggregate (MTA) using a tube-dilution test. MTA was tested freshly mixed and after 24 h set on Candida albicans. The tested MTA was incubated with C. albicans for 1 h, 24 h, and 3 days.

Introduction to Mineral Trioxide Aggregate

2014
Mineral trioxide aggregate (MTA) is a are powder primarily composed of tri- and dicalcium silicates with bismuth oxide radiopacifier. MTA has been an addition to the dental armamentarium since the 1990s. When mixed with water, MTA powder forms hard cement by hydration of the silicates.

Effect of Mineral Trioxide Aggregate on Mesenchymal Stem Cells

Journal of Endodontics, 2010
Mineral trioxide aggregate (MTA) is known to stimulate the hard tissue repair process. The purpose of this study was to evaluate the ability of MTA to support the adhesion, proliferation, and migration of human bone marrow-derived mesenchymal stem cells (hMSCs).White ProRoot MTA and white Portland cement were mixed and left to set 24 hours.

Reactions of Connective Tissue to Amalgam, Intermediate Restorative Material, Mineral Trioxide Aggregate, and Mineral Trioxide Aggregate Mixed With Chlorhexidine

Journal of Endodontics, 2006
The aim of this study was to histopathologically examine the biocompatibility of the high-copper amalgam, intermediate restorative material (IRM), mineral trioxide aggregate (MTA), and MTA mixed with chlorhexidine (CHX). This study was conducted to observe the rat subcutaneous connective tissue reaction to the implanted tubes filled with amalgam, IRM ...
