Since the emergence of problem nuclear waste conditioning, cementation has become an important and developing part management system, owing to its simplicity versatility. The continued development technique is driven by improvement expansion cementitious materials that are suitable efficient for solidification. Advances in cement theory technology have significantly impacted improvements techno...

The water to powder ratio and method of mixing is important for the properties hydraulic cements. For this purpose a number clinicians prefer premixed materials. Dental manufacturing companies provide predosed materials, however manufacturer instructions are not always adhered to. aim research investigate physical chemical alterations tricalcium silicate?based cement Biodentine when manipulated...

PURPOSE Provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations. While the functional life spans of these cements are unpredictable, the relative retentiveness of various permanent and provisional cements between dental alloys and titanium abutments is not well documented. The aim of this study was to compare the uniaxial resistance force...

ABSTRACTIntroduction: The bioactivity property of pulp capping materials is determined by the hydroxyl ion release ability, which may alter environmental pH to become alkaline. Calcium silicate-based are antibacterial, able induce reparative dentin and have a good bacteria-tight seal. poor handling calcium can be overcome adding resin, so will easier handle. Therefore, purpose this study was sy...

Objective. The aim of this study was to evaluate the radiopacity of two conventional cements (Zinc Cement and Ketac Cem Easymix), one resin-modified glass ionomer cement (RelyX Luting 2) and six resin cements (Multilink, Bistite II DC, RelyX ARC, Fill Magic Dual Cement, Enforce and Panavia F) by digitization of images. Methods. Five disc-shaped specimens (10 × 1.0 mm) were made for each materia...

Purpose: To investigate the use of tricalcium silicate cement Biodentine as an alternative to MTA in regenerative endodontic procedures by assessing morphology and adhesion stem cells from apical papilla direct contact with these materials Materials/Methods: Glass ionomer cement, disks identical size were created. Stem incubated on disks, their assessed a scanning electron microscope. Results: ...

OBJECTIVE To characterize the hydration products of white mineral trioxide aggregate (MTA). METHODOLOGY Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X-ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un-hydrated and after hydration and curing for 30 days at 37 degrees C. Analysis of hydrated cement leachate was performed week...

The use of self-adhesive resin cements is accomplished by a simple clinical step, in which the simultaneous demineralization/infiltration of the bonding substrate takes place. However, the self-adhesive resin cements have lower bond strength than conventional resin cements that rely on the application of etch-and-rinse adhesive systems. In order to increase the bond strength of the self-adhesiv...
