چکیده
Background The silicon tetrahydride or silanes is an inorganic colourless gas with spontaneous combustion in air at room temperature [1–3]. Silane or functionalized silanes has widely industrial and medical applications, and works as coupling and impermeabilizing agent. Silane coupling agents have also been applied to bond glass and carbon fibers to polymer matrices, creating a strong adhesion of fibers and filler particles to the polymer matrix [4, 5]. In Dentistry, silane coupling agents is applied to bond filler particles to resin monomers of restorative composites and also to prepare all-ceramic restorations for adhesive cementation [6]. The superficial treatments of minerals and glass fillers become them more Abstract

The Effect of Lithium Disilicate Ceramic Thickness and Translucency on Shear Bond Strength of Light-cured Resin Cement
Introduction: To achieve acceptable clinical performance, a ceramic veneer must be bonded to enamel by well-polymerized resin cement. Among different factors, thickness and translucency of the ceramic may affect the resin cement polymerization. Thus, the current study evaluated the effect of the thickness and translucency of lithium disilicate ceramic on light-cured resin cement bond strength t...

The aim of this study was to evaluate the effect of silanization protocols on the bond strength of two resin cements to a lithium disilicate glass-ceramic. Thirty-two ceramic discs were assigned to 2 groups (n=16): G1 - dual-cured resin cement and G2 - light-cured resin cement. Four subgroups were evaluated according to the used silanization protocol. The glass-ceramic was etched with 10% hydro...
