Mineral trioxide aggregate (MTA) cement is an attractive material in endodontic dentistry. The purpose of this study was to produce calcium silicate, which is a major component of MTA, from waste materials. A dental alginate impression gel and used chalks were selected and mixed in a suitable ratio (Code: EXP). As a control, CaCO3 and a commercial diatomite were used (Code: CON). Each powder wa...

introduction : solubility of root filling materials is heavily influenced by the environment they are in contact with. this study compared the solubility of proroot mta in deionized water and synthetic tissue fluid. materials & methods: forty specimens of prepared mta were immersed in deionized water and synthetic tissue fluid (20 samples each). the solubility was assessed after 7 and 28 days. ...

The physical and antibacterial properties of mineral trioxide aggregate (MTA) have been improved by adding copper nanoparticles (CuNP). CuNP colloid was synthesized reacting CuCl2·2H2O NaBH4 as the reducing agent using C6H8O6 capping agent. Cu(II) concentration varied 3.0, 6.0, 9.0 mM to produce CuNP-3, CuNP-6, CuNP-9 colloids, respectively. colloids were characterized with a UV-Vis spectrophot...

endodontic intervention in necrotic immature permanent teeth is usually a clinical challenge. with appropriate case selection, regenerative treatment can be effective, providing a desirable outcome. however, there is still no consensus on the optimal disinfection protocol or the method to achieve predictable clinical outcome. this article presents two cases of regenerative treatment in necrotic...

Introduction: This study was carried out to compare two retrograde filling materials entitled mineral trioxide aggregate (MTA) and Root MTA (RMTA) in regard to their marginal adaptation and surface defects. Method: In this study twenty extracted human teeth were used. In all teeth after cleaning and shaping, the root canals were obturated by gutta-percha and root canal sealer. After that in eac...

introduction: this study compared the apical sealing ability of a bioceramic based root canal repair filling material (iroot fs) with mineral trioxide aggregate (mta). methods and materials: forty single-canal teeth were prepared and randomly divided into two experimental groups ( n =18) and two control groups ( n =2). teeth in experimental groups were retrofilled with either mta or iroot fs. a...

background and aim: present study was designed to compare the bonding strength of resin-modified glass ionomer (rmgi) and composite resin to mineral trioxide aggregate (mta), mta mixed with na2hpo4 (namta), and calcium-enriched mixture (cem). materials and methods: thirty specimens of each cem, namta, and mta were prepared. composite and rmgi restorations were then placed on the samples (15 sam...
