Dentin adhesive systems have dramatically developed during the past decades. In a prepared cavity for an composite restoration, large areas of floor are composed caries-affected dentin after removal caries-infected dentin, not normal dentin. Caries-affected is different in morphological, chemical and physical characteristics from Therefore, has still problems as bonding substrate compared with That is, produces lower bond strength poor quality hybrid layer than addition, when exposed...
Zirconia ceramics have been widely used as dental restorations due to their esthetic appearance and high flexural strength. The bonding of zirconia with resin cement should rely on both mechanical chemical bonds.

Abstract In the current trend of materials used for dentin hypersensitivity treatment, calcium–phosphate‐containing desensitizers are expected to have advantages in oral environment. A newly formulated desensitizer containing tetracalcium phosphate and dicalcium anhydrous (CPD‐100) was evaluated comparison oxalate (SS) regarding permeability reduction (PR%) by measuring hydraulic conductance on etched discs vitro .

Purpose To evaluate the effect of a scrubbing technique with one-step self-etching adhesives on bond strengths and nanoleakage expression at resin/dentin interface. Materials methods Flat human dentin surfaces bonded one two mild adhesives, SE One (SE) or Scotchbond Universal (SU) applied either without technique, were prepared (n = 5). The microtensile (μTBS), micrographs morphological changes treated surfaces, along interfaces as shown TEM evaluated. μTBS data analyzed using two-way ANOVA...
The repair microshear bond strengths (µSBSs) to resin matrices in 4 different cured-composites after water storage (0, 60 s, 1 week, month) were evaluated. Three adhesive application methods the performed; (1) none, (2) onestep self-etch application, and (3) one-step with a silane coupling agent. Degree of conversion (DC) composite discs was determined using ATR/FT-IR time-based spectrum analysis. Initially, amount un-reacted monomers repaired cured-composite contributed bonding performance...
PURPOSE To evaluate the effect of water aging adherend composite on repair bond strength to nanofilled composites with specific fillers using different bonding agents. MATERIALS AND METHODS Three - Beautifil II S-PRG filler (BE) / Filtek Supreme ultra nanocluster (SP) Estelite Σ Quick (ES) and one microhybrid composite, Clearfil APX (AP), were used in this study. The disks immersed for durations (immediate, 1 week, 2 weeks or month), then polished surfaces treated three agents no treatment...
This study investigated the influence of application/wash-out times sodium hypochlorite (NaOCl) and hypochlorous acid (HOCl) on dentin bond strength one-step self-etch adhesives (1-SEAs). Human coronal discs with a standardized smear layer were pretreated 6% NaOCl or 100 ppm HOCl for 5 s, 15 30 washed out water s without application Clearfil DC Activator (CDA). No pretreatment was used as control. The bonded 1-SEA (Bond Force II Universal Bond Quick) microtensile (µTBS) measured after 24 h....
We evaluated the effect of different curing strategies for universal adhesives on micro-tensile bond strength (μTBS) between resin cement and dentin and/or indirect composite. Flat coronal surfaces composite disks were pretreated with silane-containing adhesives, or without light-curing dentin-side disk-side. Resin luted onto corresponding dual-cure adhesive cements light-cured, cut into beams after 24-h water storage. After 0 10,000 thermocycles (5ºC/55ºC) in a bath, μTBS disk-dentin beam...
Purpose To evaluate the effect of a reducing agent and plant-extract antioxidant on bonding durability self-etch adhesive to normal NaOCl-treated, smear-layer-deproteinized dentin. Materials methods Flat smear-layer-covered dentin surfaces from 60 extracted human molars were prepared by removing occlusal enamel. The teeth divided into two groups with or without NaOCl-deproteinizing treatment for 30 s, further three subgroups as follows: no application antioxidant, Accel (p-toluenesulfinic...
This study investigated the polymerization behavior within adhesive layer of one- and two-step self-etch adhesives at dentincomposite interface. Dentin surfaces were applied with Clearfil S(3) Bond (TS), Plus (TSP) SE (SE), then placed a light-curing resin composite. After water storage for 24 h, bonded teeth sectioned polished perpendicular to interface, degree conversion (DC) between dentin composite determined using micro-Raman analysis. For all adhesives, DCs layers significantly...
PURPOSE To evaluate the effect of a polymerization accelerator on microtensile bond strength (µTBS) etch-and-rinse and self-etch adhesives to eugenol-contaminated dentin. MATERIALS AND METHODS Sixty flat dentin surfaces were prepared from human molars. Half specimens restored with zinc oxide eugenol temporary cement (IRM) (eugenol-contaminated group) other half remained without restoration (control group).

Volumetric shrinkage (VS) of conventional, bulk-fill, and core build-up resin-based composites (RBCs) various thickness (1-5 mm) was measured using the modified bonded-disk method with confocal laser scanning microscopy. Additionally, bottom-to-top ratio Vickers hardness (%VH) measured. Conventional RBCs exhibited significantly higher VS than bulk-fill (p<0.05). As specimen increased, relative to volume (%VS) difference in at each depth (VSdepth) decreased. For conventional RBCs, there a...
