There were several materials used to seal different types of perforation defects. MTA is one of these restorative materials that is considered the most effective, biocompatible, non-toxic, and non-irritant; promote bone healing and cementum regeneration. The objective of this article was to review and summarize the sealing ability of MTA compared with the other materials used for sealing differ...

The physical and antibacterial properties of mineral trioxide aggregate (MTA) have been improved by adding copper nanoparticles (CuNP). CuNP colloid was synthesized reacting CuCl2·2H2O NaBH4 as the reducing agent using C6H8O6 capping agent. Cu(II) concentration varied 3.0, 6.0, 9.0 mM to produce CuNP-3, CuNP-6, CuNP-9 colloids, respectively. colloids were characterized with a UV-Vis spectrophot...

A number of root-repair materials have been developed by various manufacturers, including Mineral Trioxide Aggregate (MTA) that has adequate biological and physical properties of a good root repair material [1,2]. MTA has been used for apexification, perforation repair, root resorption, and as a root-end filling material. The main ingredients of MTA are silicate oxide, tricalcium oxide, tricalc...

Mineral trioxide aggregate (MTA) has shown potential as a root-end filling material. This clinical case describes the successful treatment of a premolar with an open apex using MTA and the warm gutta-percha technique. The results suggested that MTA may be used as an apical filling material in permanent teeth with multiple canals.

INTRODUCTION Mineral trioxide aggregate (MTA) can be used in the treatment of irritated vital pulp and repair of root perforations. However, the initial reaction of inflammatory cells to this material and also its setting time are not ideal. Studies have shown that disodium hydrogen phosphate (DHP), decreases the setting time of MTA, with no effect on its pH. This study was undertaken to evalua...

p-Methylthioamphetamine (MTA), was compared to p-chloroamphetamine (PCA) in a number of pharmacological assays. MTA was about 2-fold more potent than PCA at inhibiting synaptosomal uptake of [3H]5-hydroxytryptamine ([3H]5-HT), and about 7-fold and 10-fold less potent than PCA at inhibiting synaptosomal uptake of [3H]dopamine and [3H]norepinephrine, respectively. In drug discrimination assays, M...

Sepsis is a deleterious inflammatory response to infection with high mortality. Reliable sepsis biomarkers could improve diagnosis, prognosis, and treatment. Integration of human genetics, patient metabolite and cytokine measurements, and testing in a mouse model demonstrate that the methionine salvage pathway is a regulator of sepsis that can accurately predict prognosis in patients. Pathway-b...

INTRODUCTION 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. METHODS The change in color...

Introduction. Single-step apexification procedures using mineral trioxide aggregate (MTA) have been reported as favorable treatment options for teeth with an open apex, posing greater benefits compared to the other available medicaments. However, controlled apical placement of MTA is a challenging procedure to perform using orthograde approach. This case series describes the outcome of the unin...
