Mineral Trioxide Aggregate—A Review
Journal of Clinical Pediatric Dentistry, 2009Mineral Trioxide Aggregate (MTA) is a new material with numerous exciting clinical applications. MTA promises to be one of the most versatile materials of this century in the field of dentistry. Some of the appreciable properties of MTA include its good physical properties and its ability to stimulate tissue regeneration as well as good pulp response ...

Characterization of hydration products of mineral trioxide aggregate
International Endodontic Journal, 2008AbstractObjective To characterize the hydration products of white mineral trioxide aggregate (MTA).Methodology Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X‐ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un‐hydrated and after hydration and curing for 30 days at 37 °C.

Cellular response to mineral trioxide aggregate
Journal of Endodontics, 1998This investigation studied the cytomorphology of osteoblasts in the presence of Mineral Trioxide Aggregate (MTA) and examined cytokine production. MTA and Intermediate Restorative Material (IRM) were prepared and placed in separate Petri dishes. Osteoblasts (cell-line MG-63), grown to confluence in Hams F12/Dulbecco's modified Eagle's medium, were ...

Clinical applications of mineral trioxide aggregate
Journal of Endodontics, 1999An experimental material, mineral trioxide aggregate (MTA), has recently been investigated as a potential alternative restorative material to the presently used materials in endodontics. Several in vitro and in vivo studies have shown that MTA prevents microleakage, is biocompatible, and promotes regeneration of the original tissues when it is placed ...

Osteoblast biocompatibility of mineral trioxide aggregate
Biomaterials, 1999This 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.

Color stability of white mineral trioxide aggregate
Clinical Oral Investigations, 2012This 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.
