Surface Structural Change of Bioactive Inorganic Filler-Resin Composite Cement in Simulated Body Fluid

The effect of adding bioactive glass on the fluoride release of resin-modified glass-ionomer cement in simulated body fluid

Glass ionomer cements (GICs) originally designed for use as dental materials have a number of advantages over acrylic bone cements. These include nonexothermic setting reaction with no thermal damage to surrounding tissues, minimal shrinkage during gelation, the possibility of incorporation drugs and growth factors within the cement and the ability to release fluoride. It is already known that ...

Comparison of Physicochemical Surface Conditioning Methods for Adhesion of bis-GMA Resin Cement to Particulate Filler Composite and Surface Characterization

Surface potential change in bioactive polymer during the process of biomimetic apatite formation in a simulated body fluid{

A bioactive polyethylene substrate can be produced by incorporation of sulfonic functional groups (-SO3H) on its surface and by soaking in a calcium hydroxide saturated solution. Variation of the surface potential of the polyethylene modified with -SO3H groups with soaking in a simulated body fluid (SBF) was investigated using a laser electrophoresis zeta-potential analyzer. To complement the s...

Behavior of a Synthesized Bone Cement in Simulated Body Fluid

In this research, effect of soaking time of a new synthesized hydroxyapatite-based bone cement in simulated body fluid (SBF) on the final phase and strength has been studied. The powder section of the cement has been synthesized by using tricalcium phosphate, calcium carbonate and anhydrous dicalcium phosphate. The liquid phase of the cement consists of different concentrations of NaH2PO4.2H2O....

Impact of filler size and distribution on roughness and wear of composite resin after simulated toothbrushing

OBJECTIVES Nanofilled composite resins are claimed to provide superior mechanical properties compared with microhybrid resins. Thus, the aim of this study was to compare nanofilled with microhybrid composite resins. The null hypothesis was that the size and the distribution of fillers do not influence the mechanical properties of surface roughness and wear after simulated toothbrushing test. ...
