The purpose of this study was to evaluate the microtensile bond strength of a repair composite resin to a leucite-reinforced feldspathic ceramic (Omega 900, VITA) submitted to two surface conditionings methods: 1) etching with hydrofluoric acid + silane application or 2) tribochemical silica coating. The null hypothesis is that both surface treatments can generate similar bond strengths. Ten ce...

The purpose is to evaluate the effect of UV irradiation on the bond strength between epoxy-based glass fiber posts and resin cement. Twelve epoxy-based glass fiber posts were randomly divided into three groups. Group 1 (Cont.): No surface treatment. Group 2 (Low-UV): UV irradiation was conducted from a distance of 10 cm for 10 min. Group 3 (High-UV): UV irradiation was conducted from a distance...

Amaç: Bu çalışmanın amacı, basitleştirilmiş adeziv sistemlerde farklı uygulama tekniklerinin dentine olan mikrogerilim bağlanma dayanımına (μTBS) etkisini değerlendirmektir. 
 Gereç ve Yöntemler: Yetmiş iki adet çekilmiş çürüksüz insan üçüncü büyük azı dişi rastgele 18 gruba ayrıldı (n=4). Dentin yüzeyleri #600-grit silikon-karbit kağıt ile cilalandı. Kontrol grubunu Clearfil SE Bond [SE] ...

Background: Silane-containing universal adhesives (UAs) are marketed as adhesion promotors for glass-ceramics. Objectives: This study aimed to evaluate the priming capacity of γ-methacryloxypropyltrimethoxysilane (γMPTS)-containing and γ-methacryloxypropyltriethoxysilane (γMPTES)/3-(aminopropyl)triethoxysilane (APTES)-containing lithium disilicate ceramic (LDC). Materials Methods: Etched LDC di...

objective: optimal dentin bonding is not always obtained in clinical practice due to func-tional forces. these forces may provide stresses throughout the tooth and restorative sys-tem, which in turn may affect the adhesive bond. this experimental study evaluated the effect of load cycling on bond strength of self-etch systems. materials and methods: one third of the coronal portions of 48 intac...

The purpose of this paper was to compare the bond strengths of the self-adhesive luting cements between ceramics and resin cores and examine their relation to the cement thickness. Three self-adhesive luting cements (Smartcem, Maxcem, and G-CEM) and a resin cement (Panavia F 2.0) for control were used in the paper. The thickness of the cements was controlled in approximately 25, 50, 100, or 200...

Background and Aim: The aim of this study was to evaluate the micro-shear bond strength of an indirect composite resin to three different types of cores. Materials and Methods: In this in-vitro study, 14 blocks (5×5×2 mm) were designed and milled by computer from cobalt-chromium (Co-Cr) alloy, zirconia, and polyether ether ketone (PEEK). Each sample was treated according to the manufacturer’s ...

statement of the problem: self-etch adhesives can activate matrix metalloproteinase (mmp) which hydrolyzes organic matrix of demineralized dentin. epigallocatechin gallate (egcg), especially found in green tea, could inhibit the activation of mmp. purpose: the aim of this study was to evaluate the effect of adding epigallocatechin gallate (egcg) into two types of adhesives on dentin bond streng...
