PURPOSE The purpose of this study was to evaluate the effect of the degree of mismatch between post space and post diameters on the bond strength of a fiber-reinforced resin post. MATERIALS AND METHODS Thirty-two extracted human maxillary central incisors and canines were endodontically treated and assigned to four groups: Group 1--Canal prepared with a(More)
PURPOSE The objective of this project was to compare the microtensile bond strengths (microTBS) of five "all-in-one" adhesives using two 2-step adhesives as controls. MATERIALS AND METHODS Eighty-four extracted human molars were randomly assigned to one of three substrates: dentin, unground enamel, or ground enamel. For each substrate, specimens were(More)
OBJECTIVE To study the interfacial ultra-morphology formed by "all-in-one" self-etch adhesives. METHODS Forty-nine extracted molars were assigned to one of five all-in-one adhesives: Adper Prompt L-Pop (AP, 3M ESPE); Clearfil S3 Bond (S3, Kuraray); G-Bond (GB, GC America); iBond (iB, Heraeus Kulzer) and Xeno IV (XE, Dentsply Caulk). Adper Single Bond Plus(More)
OBJECTIVES Esthetic posts have been developed to maximize the foundation of esthetic restorations. The purpose of this study was to evaluate the effect of silane on the bond strength of three fiber-reinforced resin posts (fiber posts). METHODS Fifty-four extracted human maxillary central incisors and canines were endodontically treated. D.T. Light Post(More)
UNLABELLED The use of fiber-reinforced resin (FRR) posts to restore endodontically treated teeth has gained popularity as an alternative to cast or prefabricated metal posts. This may be due to the two important characteristics of fiber posts: I) their modulus of elasticity, which is similar to that of dentin, and 2) their ability to be adhesively cemented.(More)
OBJECTIVE The aim of this study was to calculate enamel bond strengths of 4 self-etch adhesives in function of conditioning time. METHODS AND MATERIALS Sixty proximal surfaces of 30 extracted human molars were roughened and assigned to 4 self-etch adhesives: AdheSE (Ivoclar Vivadent), Adper Prompt L-Pop (3M Espe), Clearfil SE Bond (Kuraray America), and(More)
OBJECTIVE The use of self-etch adhesives has increased in spite of reports of deficient enamel bonding. Some clinicians etch enamel separately to circumvent this shortfall. Therefore, the objective of this study was to assess the influence of acid-etching on the enamel sealing of 3 self-etch adhesives after thermal fatigue. METHOD AND MATERIALS Two(More)
OBJECTIVE The purpose of this in vitro study was to determine the microtensile bond strengths (mu TBS) of 3 dental adhesives when applied to dentin decalcified with ethylenediaminetetraacetic acid (EDTA). The null hypothesis tested was that the removal of calcium from dentin would not influence the bond strengths. METHOD AND MATERIALS Eighteen extracted(More)
Most manufacturers of dental adhesives have both a total-etch adhesive and a simplified self-etching adhesive available on the market. This study measured the enamel microtensile bond strengths of five pairs of enamel adhesives as a function of enamel roughness. The proximal surfaces of 25 extracted mandibular molars were sectioned with a diamond saw to(More)
PURPOSE To compare the in vitro shear bond strengths (SBS) of five simplified dentin adhesives. The tested hypothesis was that the recently introduced simplified adhesive systems would have similar or higher SBS than an existing simplified acetone-based adhesive used as a control. MATERIALS AND METHODS 100 flat bonding sites were polished to 600-grit on(More)
