PURPOSE To evaluate the in vitro microtensile bond strength (microTBS) of etch-and-rinse and self-etch adhesive systems to demineralized dentin after the use of a papain-based chemomechanical method. METHODS 36 demineralized human dentin slabs were randomly distributed into two groups according to the method of caries removal: (1). Mechanical removal with manual excavators; (2) Chemomechanica...

OBJECTIVE This study evaluated marginal integrity of bonded posterior resin composite fillings to enamel and dentine with and without 4mm flowable base, before and after thermo-mechanical loading (TML). METHODS 80 MOD cavities with one proximal box beneath the CEJ were prepared in extracted human third molars. Direct resin composite restorations (SDR with CeramX mono, Tetric EvoCeram, Filtek ...

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...

OBJECTIVES The objective of this randomized controlled clinical trial was to evaluate the 8-year clinical performance of a mild 2-step self-etch adhesive in non-carious Class-V lesions with and without prior selective phosphoric acid-etching of the enamel cavity margins. METHODS A total of 100 non-carious Class-V lesions in 29 patients were restored with Clearfil AP-X (Kuraray). The composite...

The aim of this study was to evaluate the microtensile bond strength of self-etch adhesive systems to dentin after storage in acids from oral biofilm. Three adhesive systems were used in the study: a two-step self-etch adhesive for use with a silorane-based resin composite (Filtek P90 adhesive system - P90), a two-step self-etch adhesive (Clearfil SE Bond - CSE) and a one-step self-etch adhesiv...

this in-vitro study sought to assess the push-out bond strength of a total etch and 2 self-etch bonding systems to intracanal dentin of primary anterior teeth (pat).thirty-six primary anterior teeth were randomly divided into 3 groups of 5(th) generation (single bond 2), 6(th) generation (clearfil se) and 7(th) generation (single bond universal) bonding agents. the canal orifice was restored wi...

background: the aim of this study was to compare the shear bond strength of four one-step self-etch adhesives with different ph values to enamel and dentin. materials and methods: in this in vitro study, 200 bovine permanent mandibular incisors were used. four one-step self-etch adhesives with different ph values were tested both on enamel and on dentin: adper™ easy bond self-etch adhesive (ph ...

Introduction: Adhesive dentistry faces complex clinical situations, which require the dentist to be able choose best adhesive protocol offered by universal adhesives. Objective: To present current information about performance in bond strength according etching technique used adhesives, evaluating total technique, selective enamel etching, self-etch and bonding special situations. Methodology: ...
