Two cases are reported in which incomplete placement of 4 mm mineral trioxide aggregate (MTA) plug was performed unintentionally at the apical third of permanent immature teeth with open apex and apical periodontitis. As confirmed radiographically, there were gaps between MTA and dentinal walls along the MTA-dentin interface. After setting of MTA was confirmed, endodontic treatment was complete...

BACKGROUND Permanent teeth pulp exposures have traditionally been treated with calcium hydroxide pulp capping. The aim of this study was to investigate the response of human pulp tissue which were mechanically exposed to a new material, Propolis and compare it with two existing and commonly used pulp capping agents (mineral trioxide aggregate and Dycal). METHODS Thirty-six intact human premol...

Introduction: Mineral trioxide aggregate (MTA) has numerous applications in dentistry due to various advantages. However, its long setting time has still remained a problem. The current study was conducted to investigate the effect of temperature (ambient and distilled water temperature) on the setting time of mineral trioxide aggregate (MTA). Materials and methods: This experimental study comp...

introduction: the aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (mta) and 0.2% chlorhexidine (chx) mixture to pure mta, as a pulp capping material. methods and materials: the pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with mta or mta+0.2% chx. after 2 months the animals were sacrificed and the teeth were pre...

This study investigated the ability of One-Up Bond alone and mineral trioxide aggregate (MTA), with and without a secondary seal of One-Up Bond or SuperEBA to seal saucer-shaped perforation defects in human molars. Cusps were removed, roots were amputated, and endodontic therapy completed on 40 extracted teeth. A cylindrical hole was made in each tooth from the furcation area to the chamber, in...

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 ...

BACKGROUND Some of the efforts to improve the properties of Mineral Trioxide Aggregate (MTA) include incorporation of some nanoparticles such as Titanium dioxide (TiO2). The aim of this study was to evaluate the effect of TiO2 nanoparticles on the setting time, working time, push-out bond strength and compressive strength of MTA. MATERIAL AND METHODS The physical properties to be evaluated we...

Portland cement has been analyzed and compared to mineral trioxide aggregate (MTA) because of their chemical similarity. The possibility of using this material as a less expensive alternative to MTA in dental practice should be considered. In view of this, the present study compared the components of a Portland cement (Votoran) to two commercial brands of MTA (Pro-Root and MTA-Angelus). Twelve ...
