Chemical composition and porosity characteristics of calcium silicate-based endodontic cements are important determinants of their clinical performance. Therefore, the aim of this study was to investigate the chemical composition and porosity characteristics of various calcium silicate-based endodontic cements: MTA-angelus, Bioaggregate, Biodentine, Micromega MTA, Ortho MTA, and ProRoot MTA. Th...

OBJECTIVES Recently, it was shown that NanoMTA improved the setting time and promoted a better hydration process which prevents washout and the dislodgment of this novel biomaterial in comparison with WTMA. This study analyzed the compressive strength of ProRoot WMTA (Dentsply), a NanoWMTA (Kamal Asgar Research Center), and Bioaggregate (Innovative Bioceramix) after its exposure to a range of e...

Purpose: This in vitro study compared the effects of mineral trioxide aggregate (MTA), BioAggregate and calcium hydroxide on hydroxyl ion diffusion through dentinal tubules to root surfaces without cementum various levels. 
 Materials & Methods: The consisted 120 mature single-rooted mandibular premolar teeth. teeth were decoronated instrumented using Protaper Universal rotary files. T...

background and aims. biocompatibility of root-end filling materials is a matter of debate. the aim of this study was to compare the biocompatibility of a variety of commercial proroot wmta cements and a resin-based cement (geristore®) with different ph values of setting reaction and different aluminum contents, implanted into the subcutaneous connective tissue of rats at various time intervals....

AIM To compare the ability of Ceramicrete, BioAggregate and white ProRoot MTA (mineral trioxide aggregate) to prevent glucose leakage through root-end fillings. METHODOLOGY After root canal instrumentation, the apical 3 mm of maxillary incisors were resected and retropreparations, 3 mm in depth, were created with ultrasound. Root-end cavities were filled with the tested materials (15 roots pe...

OBJECTIVES The aim of this study was to evaluate marginal adaptation of mineral trioxide aggregate (MTA), calcium enriched mixture (CEM) cement, Biodentine and BioAggregate in presence of normal saline and human blood. MATERIALS AND METHODS In this in-vitro experimental study, 80 extracted single-rooted human teeth were instrumented and filled with gutta-percha. After resecting the root-end, ...
