Reparability of Aged Silorane With Methacrylate-Based Resin Composite: Micro-Shear Bond Strength and Scanning Electron Microscopy Evaluation

Abstract

The silorane-methacrylate group without any IL showed the lowest bond strength values (0.4 ± 0.1 MPa). The use of a methacrylate-based IL (1.6 ± 1.7 MPa) led to a slight increase in bond strength, whereas the use of phosphate-methacrylate IL (9.1 ± 5.4 MPa) significantly increased bond strength. There was no statistically significant difference in bond strength between silorane-silorane (7.9 ± 3.6 MPa) and methacrylate-methacrylate (9.5 ± 4.1 MPa) groups without any IL.

Effect of temporary cements on the bond strength of a resin cement to a pre-hybridized dentin

“…The present study used the microshear bond test, which allows small areas to be tested, and it has the same advantages as the microtensile bond strength test, without the need for sectioning procedures to obtain specimens, as these laboratory procedures themselves may induce early micro-cracking within the specimen (ANDRADE et al, 2010). A better stress distribution can be accomplished in smaller specimens, using microshear bond strength testing, since the number of voids and stress-raising factors is lower than the ones that possibly occur in larger areas, such as those used for shear or tensile bond strength tests (GIACHETTI et al, 2012).…”

“…However, eugenol (2-methoxi-4-allyphenol) is a radical scavenger and may inhibit the polymerization of resin materials (GIACHETTI et al, 2012). The hydroxyl group of the eugenol molecule tends to protonize the free radicals formed during polymerization of the resin material, thereby blocking their reactivity, reducing the degree of conversion and, consequently, bond strength (BAYINDIR et al, 2003;YAP et al, 2001).…”

Effect of the superficial treatment in the repair of silorane-based composite aged artificially

“…The repair os silorane-based composite aged articially Although silorane-based composite repair has been investigated in recent studies [11][12]16 , most of these studies did not submit the restoration to aging before repair [10][11]14,16,21 . In literature, there are only a few studies that aged the specimens before the repair and the period of aging in these articles was relatively short, ranging from 3 days to 6 months [12][13]18 . Likely, the analysis of repair stability, after aging, was little investigated in previous studies 16. Considering the above discussion, the aim of this study was to evaluate the effect of repair aging of some surface treatments in the repair bond strength of siloranebased composite aged artificially.…”

Effect of surface conditioning methods, adhesive systems and resin composite on repair strength of dimethacrylate and silorane resin composites

“…However, limited information is available on the repair potential of low shrinkage silorane composite and its compatibility with the methacrylate-based resin composite [10][11][12][13][14][15].…”

“…Although previous studies have evaluated the silorane repair [10][11][12][13][14][15], none of them investigated the influence of other adhesives different than the silorane specific adhesive in combination with different surface conditioning methods and resin composites.…”
