Removal of White Mineral Trioxide Aggregate Cement: A Promising Approach
Removal of MTA from dentin by applying 37% hydrochloric acid (HCl) to reduce microhardness and push-out bond strength. Forty dentin slices were filled with WMTA and divided into two groups (n = 20). Ten slices remained untreated while others were exposed to either HCl or phosphate buffer saline (PBS) and all samples were subjected to pushout test. The mode of bond failures was determined by SEM...
متن کاملSetting expansion of gray and white mineral trioxide aggregate and Portland cement.
One possible reason for the sealing ability of mineral trioxide aggregate (MTA) is its slight expansion upon setting. Both gray mineral trioxide aggregate (GMTA) and white mineral trioxide aggregate (WMTA) are composed of approximately 75% Portland cement (PC). WMTA differs from GMTA in its lower content of tetracalcium aluminoferrite. This difference in composition may affect setting expansion...
متن کاملIn Vitro Cytotoxicity and Setting Time Assessment of Calcium-Enriched Mixture Cement, Retro Mineral Trioxide Aggregate and Mineral Trioxide Aggregate
Introduction The present study sought to evaluate and compare biocompatibility and setting time of Retro mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) and Angelus MTA. Methods and Materials CEM cement, Angelus MTA and Retro MTA were assessed in set and fresh states. Extracts transformed to each cavity of three 24-well plates in which 1×104 cell were seeded into each well 24...
متن کاملSuperfast Set, Strong and Less Degradable Mineral Trioxide Aggregate Cement
Purpose Despite the good sealing ability and biocompatibility of mineral trioxide aggregate (MTA), its slow setting, high degradation, and weakness limit its use in surgical endodontics and high stress-bearing areas. This study aimed to develop two new liquids to control these drawbacks. They were prepared from calcium chloride, fumed silica, and hydroxyapatite or calcium phosphate and coded "H...
متن کاملMineral Trioxide Aggregate : A Review
The main aim of an ideal retrograde filling material is to seal the pathways of communication between surrounding tissues and the root canal system , hence mineral trioxide aggregate (MTA ) which is a biocompatible and a nontoxic material was developed for dentistry. This material allows normal healing response due to the formation of new cementum and bone. Calcium and phosphorus are the main i...
