introduction: the aim of this in vitro study was to evaluate the tooth discoloration induced by calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: forty five endodontically treated human maxillary central incisors were selected and divided into three groups ( n =15) after removing the coronal 3 mm of the obturating materials. in the mta group, whi...

introduction : the aim of this quantitative systematic review/meta-analysis was to compare the treatment outcomes of mineral trioxide aggregate (mta) and calcium hydroxide (ch) in pulpotomy of human primary molars. the focused pico question was “in case of pulp exposure in vital primary molars, how does mta pulpotomy compare to ch in terms of clinical/radiographic success?” methods and material...

introduction : this in vitro study was designed to evaluate the effect of smear layer removal on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture cement (cem). materials and methods: dentin discs with 3 mm thicknesses were divided into 4 groups ( n =15): group 1: irrigation of the canal with normal saline and filling with wmta; group 2: irrigation w...

introduction : the aim of this in vitro study was to evaluate the effect of smear layer on the push-out bond strength of white mineral trioxide aggregate (wmta) with and without disodium hydrogen phosphate (na 2 hpo 4 ). materials and methods: dentin discs with standard cavities were obtained from extracted human single-rooted teeth and divided to 4 groups ( n =15) according to the irrigation r...

objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...

there is some concern that root resection may alter the seal of the previously set orthograde material. the aim of this study was to evaluate the apical sealing ability of orthograde mineral trioxide aggregate (mta) and calcium enriched mixture (cem) plugs after resection of the roots.the fluid filtration method was carried out on a total of 51 roots in three experimental (n=15) and two control...

The use of mineral trioxide aggregate (MTA) for complete endodontic obturation of an immature maxillary central incisor is reported. The injured tooth of a 9-year-old male was avulsed secondary to a sports-related traumatic event. Early attempts at pulpal revascularization of the replanted tooth proved unsuccessful, as evidenced by radiographic signs of external inflammatory root resorption in ...

Mineral trioxide aggregate (MTA) has shown potential as a repair material for perforations. This clinical case demonstrates that when MTA was used as a repair material for root perforation due to invasive cervical resorption, the tooth was well in function for 27 months. Both clinical and radiographic follow-up showed a stable condition without any probing defect, ongoing root resorption, or ap...

The aim of this study was to histopathologically examine the biocompatibility of the high-copper amalgam, intermediate restorative material (IRM), mineral trioxide aggregate (MTA), and MTA mixed with chlorhexidine (CHX). This study was conducted to observe the rat subcutaneous connective tissue reaction to the implanted tubes filled with amalgam, IRM, MTA, and MTA mixed with CHX. The animals we...
