This study evaluated the microtensile bond strength (TBS) of 1-step self-etch adhesives (1-SEAs) and 2-step self-etch adhesives (2-SEAs) to pulp chamber dentin immediately after bleaching with 2 types of common bleaching techniques. Pulp chamber dentin of bovine teeth was bleached using 30% hydrogen peroxide (HO) solution with quartz-tungsten-halogen light-curing unit (Group 1) and 3.5% HO-containing titanium dioxide (TiO) (Pyrenees®) activated with 405-nm violet diode laser for 15 min (Group 2). Unbleached specimens were placed in distilled water for 15 min and used as controls. After treatment, dentin was bonded with resin composite using 1-SEA or 2-SEA and stored in water at 37°C for 24 h. Each specimen was sectioned and trimmed to an hourglass-shape and TBS was measured. Fractured specimens were examined under a scanning electron microscope to determine fracture modes. All specimens in Group 1 failed before proper bonding tests. In Group 2, the TBS of 2-SEA was significantly greater (with no failed specimens) than 1-SEA (where 21 out of 36 failed). These results indicate that 2-SEA is a better adhesive system than 1-SEA on bleached dentin. Our results also demonstrated that application of HO significantly decreases bond strength of resin to dentin; however, in the case of nonvital tooth bleaching, Pyrenees® is a better alternative to the conventional 30% HO bleaching.

Objectives: To evaluate the shear bond strength (SBS) of universal cements (UCs) to dentin prepared with different diamond burs using various adhesive strategies.
Materials And Methods: One-hundred-twenty molars were prepared to expose the mid-coronal dentin. The teeth were divided into two groups according to diamond bur preparations: coarse and super-fine grit burs.

Purpose: This study aimed to investigate the effect of chlorhexidine (CHX) cavity disinfectant on interfacial microleakage and micro-tensile bond strength (μTBS) of a universal adhesive bonded to dentin in both self-etch (SE) and etch-and-rinse (ER) modes.
Methods: Class I cavities were prepared in the coronal dentin of extracted human teeth and assigned to two etching modes (SE or ER), then subdivided by disinfection with or without CHX (n = 5). Cavities were restored using Single Bond Universal Adhesive and Filtek Z350 XT composite.

Objective: This randomized controlled trial compared the 1-year clinical efficacy of Scotchbond Universal Adhesive Plus (SBU+) with that of its predecessor Scotchbond Universal Adhesive (SBU) to restore Class I and Class II preparations using the self-etch strategy in adult patients.
Materials And Methods: Fifty-one subjects participated in this study. Two posterior teeth in each subject were randomized to a restoration with SBU+ or to a restoration with SBU (control) using the self-etch strategy.

Objectives: To evaluate the self-etch bonding potential of universal adhesive systems with varying acidic compositions by analyzing the wettability properties, topographical change, and microshear bond strength (µSBS) to enamel.
Methods: Eight universal adhesives were tested: All-Bond Universal (Bisco), Ambar Universal (FGM), Gluma Bond Universal (Kulzer), OptiBond Universal (Kerr), Peak Universal Bond (Ultradent), Prime&Bond Universal (Dentsply), Singlebond Universal (3 M ESPE), and Tetric N-Bond Universal (Ivoclar). Bovine incisors were prepared and treated with each adhesive according to the manufacturer's instructions.

Objective: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes of adhesion according to the FDI criteria. The primary outcome was the retention loss of the restorations, while the secondary outcomes included marginal staining, marginal adaptation, post-operative sensitivity and tooth vitality, recurrence of caries erosion and abfraction, and tooth integrity, all evaluated according to the FDI criteria.
Materials And Methods: In this study, the SBU Adhesive was applied to 246 NCCLs of 25 patients using different modes of adhesion: Self-etch (SE), selective-enamel-etching (SLE), and etch-and-rinse (ER).
