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(More)
One-step adhesives bond less effectively to enamel/dentin than do their multi-step versions. To investigate whether this might be due to phase separation between adhesive ingredients, we characterized the interaction of 5 experimental and 3 commercial self-etch adhesives with dentin using transmission electron microscopy. All adhesives were examined for(More)
OBJECTIVES Flexure at the tooth cervix has been suggested to dislodge cervical restorations more rapidly. The objective of this randomized controlled clinical trial was to test the hypothesis that a higher composite flexibility better withstands tooth flexure stress. METHODS One hundred and forty-two non-carious cervical lesions were restored with(More)
PURPOSE The purpose of this prospective randomized controlled clinical study was to evaluate the clinical performance of a "mild" two-step self-etching adhesive, Clearfil SE, in Class V restorations after 5 years of clinical functioning. MATERIALS AND METHODS Twenty-nine patients received two or four restorations following two randomly assigned(More)
OBJECTIVES To evaluate the effect of bulk-filling high C-factor posterior cavities on adhesion to cavity-bottom dentin. METHODS A universal flowable composite (G-ænial Universal Flo, GC), a bulk-fill flowable base composite (SDR Posterior Bulk Fill Flowable Base, Dentsply) and a conventional paste-like composite (Z100, 3M ESPE) were bonded (G-ænial Bond,(More)
OBJECTIVES The aim of the overview is to critically analyse the contributing factors to the biological wear process and to screen the wear simulators in dentistry for their capacity to mimic the wear conditions. An overview of the types of wear, grouped as biotribocorrosion, combined with a description of the different wear simulating devices will allow us(More)
The mechanisms behind bond degradation are still largely unknown, in particular with respect to self-etch adhesives. One-step adhesives have been especially documented with problems, such as insufficient polymerization, water-uptake and subsequent plasticization, water- and enzyme-induced nanoleakage, and/or the presence of voids due to phase-separation or(More)
PURPOSE The aim of this prospective randomized controlled clinical trial was to evaluate the 2-year clinical performance of a self-adhesive resin cement, RelyX Unicem (3M ESPE), used for cementation of ceramic inlays. In addition, the influence of selectively acid etching enamel prior to luting on marginal integrity, inlay integrity, tooth integrity,(More)
The favorable self-adhesiveness of resin-modified glass ionomers (RMGIs) might be even further improved if the time-consuming and technically sensitive etch-and-rinse pre-treatment step with polyalkenoic acids could be avoided. We undertook this study to assess the effectiveness of an experimental self-etch adhesive for RMGIs that does not need to be rinsed(More)
OBJECTIVES Porcelain veneers are steadily increasing in popularity among today's dental practitioners for conservative restoration of unaesthetic anterior teeth. As with any new procedure, in vitro and in vivo investigations are required to assess the ultimate clinical efficacy of these restorations. The current literature was therefore reviewed in search(More)
