The chemical composition of mineral trioxide aggregate

Journal of Conservative Dentistry, 2008
Mineral trioxide aggregate (MTA) is composed of Portland cement, with 4:1 addition of bismuth oxide added so that the material can be detected on a radiograph. The cement is made up of calcium, silicon and aluminium. The main constituent phases are tricalcium and dicalcium silicate and tricalcium aluminate. There are two commercial forms of MTA, namely

Development of a Nano‐Hybrid Composite Using Bovine Hydroxyapatite and Montmorillonite for Endodontic Applications—An In Vitro Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim Hydraulic calcium silicate cements are widely employed in endodontics due to their excellent biocompatibility, bioactivity, sealing ability, and remineralisation potential. However, currently used products such as mineral trioxide aggregate (MTA) exhibit several limitations, including discolouration, cost, and poor handling properties ...

Mineral trioxide aggregate apexification: A novel approach

Journal of Conservative Dentistry, 2016
The treatment of choice for necrotic teeth with immature root is apexification, which is induction of apical closure to produce more favorable conditions for conventional root canal filling. The most commonly advocated medicament is calcium hydroxide although recently considerable interest has been expressed in the use of mineral trioxide aggregate ...

Regenerative Endodontics in Teeth With Irreversible Pulpitis: A Scoping Review

International Endodontic Journal, EarlyView.
ABSTRACT Introduction Regenerative endodontic procedures (REPs) have been widely used to manage a range of pulpal pathologies, particularly in immature permanent teeth. The development of bioactive calcium silicate–based materials has led to a paradigm shift in vital pulp therapy (VPT) and REPs.

Prevention of Tooth Discoloration Due to Calcium-Silicate Cements: A Review

Dental Hypotheses, 2019
Introduction: Mineral trioxide aggregate (MTA) and other calcium silicate cement similar to that are widely used in endodontic treatments. One of the widely emphasized disadvantages of these cements are the induction of tooth discoloration.

An Updated Classification of Hydraulic Cements Used in Dentistry

International Endodontic Journal, EarlyView.
ABSTRACT Mineral trioxide aggregate (MTA) was the first hydraulic cement used in endodontics. It is composed of Portland cement, a binder in concrete, and bismuth oxide to enhance the radiopacity. MTA was introduced in dentistry to be used as a root‐end filling material and also to repair root perforations.
