Aim To evaluate the inﬂuence of mineral trioxide aggregate (MTA) on apexiﬁcation and periapical heal-ing of teeth in dogs with incomplete root formation and

Effect of Aggregate, Cement, and Mineral Admixtures on

2011-2-21 Two types of aggregate, two different cement, and three mineral admixtures were investigated. Using cement paste-polished aggregate composite specimens cured up to three years, X-ray diffraction, scanning electron microscopy, and microhardness testing techniques were used for characterization of the transition zone.

Effects of mineral trioxide aggregate on human dental

Mineral trioxide aggregate (MTA) has proved to be effective in the process of pulp capping. Methods: Human dental pulp stromal cells (DPSCs) were cultured on gray MTA, and the levels of gene expression, secretion of vascular endothelial growth factor, and the surface morphology were analyzed. Results: MTA promoted cell survival and
