Mineral trioxide aggregate (MTA) was developed in early 1990s and has been successfully used for root perforation repair, root end filling, and one-visit apexification. MTA is composed mainly of tricalcium silicate and dicalcium silicate. When MTA is hydrated, calcium silicate hydrate (CSH) and calcium hydroxide is formed. Formed calcium hydroxide interacts with the phosphate ion in body fluid ...

BACKGROUND Although, mineral trioxide aggregate (MTA) and new experimental cement (CEM) are good root filling cements, but had no or low antimicrobial activities. The aim of this study was to evaluate the effects of addition of silver nanoparticles (SNP) to these two cements on antimicrobial effects against five most dental infection related microorganisms. MATERIAL AND METHODS Two suspension...

One of the most revolutionary materials introduced in Endodontics was the Mineral Trioxide Aggregate (MTA). The investigations regarding MTA formulation allowed researchers to disclose the composition and also some clinical problems related to the clinical application of this material. The augmentation on MTA’s studies resulted in the development a new generation of Endodontic materials, the ca...

introduction: in apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. mineral trioxide aggregate (mta) is the gold standard material for this purpose. changing water/powder ratios of mta affects its properties. the purpose of this in vitro study was to determine the effect of liquid/powder ratio of retrofil...

Mineral Trioxide Aggregate (MTA) is a new material recently approved by the FDA for use in pulpal therapy. MTA has been reported to have superior biocompatibility and sealing ability and is less cytotoxic than other materials currently used in pulpal therapy. This report is a review of MTA's physical and biological properties and the clinical techniques of direct pulp capping, apexification, an...

Mineral trioxide aggregate (MTA), has been successfully used in difficult endodontic situations such as immature pulp less teeth and vital pulp therapy. Portland cement (PC), which forms the bulk of MTA, has been reported to exhibit similar properties. The physical properties and biocompatibility of PC has been researched in vitro and on animals, with a few studies on humans as well. This artic...

Introduction: Both Mineral Trioxide Aggregate (MTA) and Portland cement (PC) have been highlighted because of their favorable biological properties, with extensive applications in Endodontics, including the possibility of using into root canal filling. Objective: This article reviews literature related to MTA and PC comparing their physical, chemical and biological properties, as well as their ...
