The Effect of a Physiologic Solution pH on Properties of White Mineral Trioxide Aggregate

Journal of Endodontics, 2009
The purpose of this study was to investigate the effect of two solutions differing by pH (6.4 and 4.0) and the use of a setting accelerator (15% Na(2)HPO(4) solution) on the properties of white-colored mineral trioxide aggregate (WMTA). These studies indicated that pH 4.0 had a deleterious effect on the morphology of WMTA mixed with water, however, not

Color Stability of White Mineral Trioxide Aggregate in Contact with Hypochlorite Solution

Journal of Endodontics, 2014
One of the uses of white mineral trioxide aggregate (MTA) is as an apical barrier in immature teeth. Although this treatment has been reported to have high success rates, a number of cases of discoloration have been noted. The aim of this research was to investigate the color stability of white MTA in contact with various solutions used in endodontics ...

Effect of storage temperature on sealing ability and solubility of White Mineral Trioxide Aggregate

Acta Odontologica Scandinavica, 2011
Knowledge about the effect of storage conditions on the clinical performance of Mineral Trioxide Aggregate (MTA) is of great importance for clinicians. The aim of this study was to evaluate the effect of storage temperature on sealing ability and solubility of white MTA.This study was divided into two parts: sealing ability and solubility tests.

Biocompatibility and Mineralization Activity of Fresh or Set White Mineral Trioxide Aggregate, Biomimetic Carbonated Apatite, and Synthetic Hydroxyapatite

Journal of Endodontics, 2010
The purpose of this study was to evaluate the effect of apatite formation on tissue contact with white mineral trioxide aggregate (WMTA) and compare this apatite with a synthetic hydroxyapatite (SHAp) in subcutaneous connective tissue of rats.Thirty-three Wistar rats were used in this study.

Genotoxicity in primary human peripheral lymphocytes after exposure to regular and white mineral trioxide aggregate

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2006
Taking into consideration that DNA damage plays an important role in carcinogenesis, the purpose of this study was to evaluate whether regular and white mineral trioxide aggregate (MTA) are able to induce genetic damage in primary human cells.Human peripheral lymphocytes obtained from 10 healthy volunteers were exposed to 2 presentation forms of MTA at

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.

Influence of White versus Gray Mineral Trioxide Aggregate on Inflammatory Cells

Journal of Endodontics, 2008
The aim of this investigation was to compare the quantity of inflammatory cells in response to white and gray mineral trioxide aggregate (MTA) in subcutaneous connective tissue of rats. Fifty Wistar rats were used in this study. Polyethylene tubes were filled with gray or white MTA and empty ones serving as the control group were implanted into ...

Effects of Gray and White Mineral Trioxide Aggregate on the Proliferation of Oral Keratinocytes and Cementoblasts

Journal of Endodontics, 2006
Mineral trioxide aggregate (MTA) is used as a repair material and may directly contact cells from different cell lineages. The purpose of this study was to assess cell proliferation of immortalized Murine cementoblasts (OCCM.30) and immortalized keratinocytes (OKF6/TERT1) on gray MTA (GMTA) and white MTA (WMTA) with the DNA intercalating dye Hoechst ...
