This study evaluated the bonding compatibility between dual-cured resin cements and simplified adhesive systems (one-step self-etch and two-step etch & rinse), measured after 24 hours and 3 months. The occlusal dentin surfaces of 24 human third molars were exposed and flattened. Teeth were randomly assigned to 3 groups and treated with different combinations of adhesive system and resin cement ...

The objective of this study was to evaluate the effectiveness of a self-etching primer, Transbond Plus Self Etching Primer (TSEP, 3M Unitek), and a non-rinse conditioner (NRC, Dentsply DeTrey) for bonding brackets, compared with the acid-etch technique. The brackets were bonded to extracted premolars using Transbond XT (3M Unitek). One of the following three conditioning protocols were used: (1...

Objective: To evaluate the microleakage of three self-adhesive cements and one etch & rinse resin cement on dentin and enamel interfaces. Methods: Forty-eight inlays preparations (n=12) with enamel and dentin margins were performed on extracted teeth. After impressions, indirect composite inlays were manufactured and luted with self-adhesive resin cements (RelyX U100, Maxcem or SpeedCem) or an ...

The purpose of this study was to test the hypothesis that a torsional load applied after bracket bonding does not affect the shear bond strength (SBS) with different bonding techniques. Sixty human premolars were divided into two groups (experimental and control) to investigate the effects of a torsion load, and the two groups were further subdivided into three groups of 10 for the evaluation o...

GREICE OLIVEIRA: Influence of tooth age and application time on the microtensile bond strengths of different adhesive systems to dentin. (Under the direction of André V. Ritter) This study evaluated the effect of tooth age and application time on the microtensile bond strengths (µTBS) of different adhesives to dentin. One-hundred twenty intact human teeth were mechanically ground to expose mid-...

OBJECTIVES To evaluate the effect of application time on the resin-dentin bond strength (µTBS) and etching pattern of adhesive systems applied on sclerotic dentine. MATERIAL AND METHODS A total of forty-two bovine incisors had their roots removed. The 1-step self-etch GO (SDI), the 2-step self-etch Adper SE Bond (3MESPE) and the 35% phosphoric acid (3MESPE) from the 2-step etch-and-rinse Adpe...

The aim of this study was to evaluate biocompatibility of an etch-and-rinse adhesive system based in tertiary butanol applied in deep cavity human teeth with approximately 1 mm of remaining dentin by observing histological changes of the pulp tissue of humans at intervals of 01, 07, 14 and 21 days. Twenty third molars with indication for xtraction from patients of both sexes, presenting no syst...

BACKGROUND Antioxidizing agents have recently been suggested to compensate decreased bond strength of resin materials to bleached tooth tissues. This study compared the shear bond strength (SBS) of three different adhesives on bleached dentin immediately after bleaching, bleached/delayed for 1 week, and bleached/applied antioxidizing agent. MATERIALS AND METHODS The dentinal surfaces of 132 i...
