introduction: mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. recently, a material similar to proroot mineral trioxide aggregate (pmta) was developed in iran named root mineral trioxide aggregate (rmta) with the claim of having the exact result of original mta. the purpose of this study was to compare the a...

i ntroduction: many of highly-alkaline dental materials have some adverse effects on physical properties of dentin. as basic substances, mineral trioxide aggregate (mta), calcium hydroxide (ch) and the new endodontic material, calcium-enriched mixture (cem) cement, may adversely affect dentin. the purpose of this in vitro study was to evaluate the effect of long-term application of cem cement, ...

background: introducing new endodontic cements should await comprehensive investigations and new formulations have to be tested in vivo before applying in human beings. so, the purpose of this study was to compare the biocompatibility of new endodontic cements, calcium aluminate α-aluminate cement (caac), calcium aluminate α-aluminate plus cement (caac plus), and a mixture of wollastonite and c...

This study evaluated the root-end sealing ability of mineral trioxide aggregate (MTA Angelus), reinforced zinc oxide-eugenol cement (Super EBA), resin-modified glass ionomer (Vitremer) and zinc-free amalgam (GS-80) (control). The root canals of eighty human lower molars were accessed, cleansed, shaped and obturated. Apexes were resected and cavities were prepared. Teeth were divided into 4 grou...

Objective:  To investigate the tissue response and biomineralization ability of CER prepared with epoxy resin or water compared to Mineral Trioxide Aggregate (MTA) .  Material Methods:  Polyethylene tubes containing materials empty for control were inserted into subcutaneous tissues 30 rats. After 7, 15, 30, 60, 90 days, rats killed removed analysis using hematoxylin-eosin staining, von Kossa u...

Dens invaginatus, also known as “dens in dente”, is a developmental dental anomaly resulting in an invagination of the enamel organ into the dental papilla. These cases present technical difficulties to the root canal treatment. Apexification using an apical plug of mineral trioxide aggregate (MTA) has been indicated as an alternative to long-term intracanal use of calcium hydroxide in immature...

Mineral trioxide aggregate (MTA) has emerged as a reliable bioactive material with extended applications in endodontics that include the obturation of the root canal space. This article examines the literature supporting MTA as a canal filling material, suggests methods for its delivery and placement, and presents clinical cases that demonstrate its effectiveness in resolving apical periodontit...

Endodontic surgical procedures involve the use of a root-end filling material to provide an apical seal and to facilitate the repair and regeneration of periradicular tissues. Whereas earlier studies typically evaluated the cytotoxicity of these materials, contemporary research has focused on their capacity to support a favourable cellular response. In vitro tissue culture techniques have demon...
