Single-step self-etch adhesive systems have been developed to simplify and shorten bonding procedures. With the gain in popularity of these simplified systems, their reliability has become a focus of interest. The purpose of this study was to determine the effect of adhesive application method on enamel bond strength. Two commercial single-step self-etch adhesive systems, Clearfil tri-S Bond, a...

OBJECTIVES This study examined the effects of additional acid etching on the dentin bond strength of one-step self-etch adhesives with different compositions and pH. The effect of ethanol wetting on etched dentin bond strength of self-etch adhesives was also evaluated. MATERIALS AND METHODS Forty-two human permanent molars were classified into 21 groups according to the adhesive types (Clearf...

OBJECTIVE To evaluate the ability of the resin-coat technique used in cavity preparation to protect dentin before impression taking and final cementation and its effect on the tensile bond strength of indirect restorations after thermal and load cycling. METHODS Occlusal enamel was removed from 25 third molars to expose flat dentin. Teeth were divided into 5 groups (n=5): G1, receiving no den...

Objective: To assess biofilm proliferation within the sealer-dentin interfaces of methacrylate resin-based sealers, self-etch (SE) and total-etch (TE), and an epoxy resin-based sealer (EP). Methods: Standardized human root specimens were filled with the test materials and were aged for 1 week, 1, 3 or 6 months in saline (n=3/group). Monoclonal biofilms of Enterococcus faecalis were grown on the...

OBJECTIVE To evaluate the effect of optional phosphoric acid etching on the shear bond strength (SBS) of two self-etch adhesives to enamel and dentin. MATERIAL AND METHODS Ninety-six bovine mandibular incisors were ground flat to obtain enamel and dentin substrates. A two-step self-etch adhesive (FL-Bond II) and a one-step self-etch adhesive (BeautiBond) were applied with and without a prelim...
