In vitro bond strengths of three resin adhesive systems were tested using 111 primary teeth. Ninety-six flat dentin surface specimens were divided into six groups consisting of 16 primed or 16 unprimed samples for each adhesive system. The remaining 15 tooth samples were divided into three groups of five to determine each adhesive system's bond strength to primary etched enamel. Resin buttons w...

background: application of bonding agents (ba) into deep cavities and light curing them might increase pulpal temperature and threaten its health. the purpose of this study was to evaluate temperature rise of pulp by light curing six ba using two different light curing units (lcu), through a dent in wall of 0.5 mm. materials and methods: this in vitro experiment was carried out on 96 slices of ...

BACKGROUND Bond strength of adhesive layer can absorb unwanted stresses of polymerization shrinkage in composite resin restorations; increased microshear bond strength can prevent failure of restoration materials, the purpose of this study was to evaluate the effect of adhesive layers on microshear bond strength of nanocomposite resin to dentin. MATERIAL AND METHODS Two different types of adh...

The aim of this study was to investigate the effects of plasma-enhanced deposition of an organosilane and benzene on resin bonding to a dental zirconia ceramic. A total of 70 zirconia specimens, which were polished before sintering, were randomly divided into five groups according to surface treatments before applying a dental adhesive (each group, n = 14): group 1, no previous treatment (contr...

background and aims. effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. the aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µsbs) of silica- (spectrum tph) and zirconia-filled (filtek z250) composite resins. materials and methods. twenty-seven composite resin blocks...

OBJECTIVES The aim of this study was to investigate the bond strength of ceramic restorations luted using a self-adhesive resin cement (RelyX Unicem, 3M ESPE) under different dentin conditions. MATERIAL AND METHODS In the experimental groups, ceramic restorations were luted to bovine incisors with RelyX Unicem under the following conditions: [Dry dentin]: surface was dried using air stream fo...

This study evaluated in vitro the shear bond strength (SBS) of a resin-based pit-and-fissure sealant [Fluroshield (F), Dentsply/Caulk] associated with either an etch-and-rinse [Adper Single Bond 2 (SB), 3M/ESPE] or a self-etching adhesive system [Clearfil S3 Bond (S3), Kuraray Co., Ltd.] to saliva-contaminated enamel, comparing two curing protocols: individual light curing of the adhesive syste...
