AIM To evaluate the influence of salivary contamination during dentin bonding procedures on shear bond strength and to investigate the effect of contaminant-removing treatments on the recovery of bond strength for two dentin-bonding agents. MATERIALS AND METHODS Seventy-seven human maxillary and mandibular molars were randomly divided into two groups for total-etch adhesive (Single bond-3M ES...

Restorative dentistry is mainly based on good adhesion between restorative materials and dental substrates; while adhesion to enamel is generally reliable, adhesion to dentin is less predictable (1) because of the presence of dentinal tubulis and the perfusion of liquids from it. Adhesion to dentin requires demineralization of peritubular and intertubular dentin to replace the demineralized lay...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...

OBJECTIVES The purpose of this randomized controlled clinical trial was to test the hypothesis that a two-step self-etch approach is equally effective to restore cervical class-V lesions as a self-etch approach with beforehand selective etching of enamel using phosphoric acid. METHODS Twenty-nine patients received two or four restorations randomly following two experimental protocols ('paired...

BACKGROUND Mineral trioxide aggregate (MTA) is a biomaterial that has been investigated for endodontic applications. With the increased use of MTA in pulp capping, pulpotomy, perforation repair, apexification and obturation, the material that would be placed over MTA as a final restoration is an important matter. As composite resins are one of the most widely used final restorative materials, t...

OBJECTIVE The purpose of this study was to evaluate the influence of Er:YAG laser irradiation on the bond strength to dentine of three single-step adhesives (AQ Bond Plus, G-Bond, and Clearfil Tri-S Bond), and one two-step self-etch adhesive (Clearfil Megabond) as a control. BACKGROUND DATA The vast majority of the numerous reports on resin bonding to Er:YAG-lased dentine have concluded that ...

OBJECTIVES This study evaluated mechanically and ultra-morphologically 11 different adhesive systems bonded to dentin. METHODS The microtensile bond strength (microTBS) of 11 contemporary adhesives, including two three-step etch&rinse, three two-step etch&rinse, two two-step self-etch and four one-step self-etch adhesives to dentin, were measured. The resultant interfacial ultra-structure at ...

OBJECTIVES This study evaluated the influence of chlorhexidine (CHX) on the microtensile bonds strength (µTBS) of resin core with two adhesive systems to dentin in endodontic cavities. MATERIALS AND METHODS Flat dentinal surfaces in 40 molar endodontic cavities were treated with self-etch adhesive system, Contax (DMG) and total-etch adhesive system, Adper Single Bond 2 (3M ESPE) after the fol...

OBJECTIVES The bonding effectiveness of five adhesive luting agents to enamel and dentin using different application procedures was determined using a micro-tensile bond strength protocol (microTBS). METHODS Enamel/dentin surfaces of human third molars were flattened using a high-speed diamond bur. Composite resin blocks (Paradigm, 3M ESPE) were luted using either Linkmax (LM; GC), Nexus 2 (N...
