OBJECTIVE To test the hypothesis that the quality of the dentinal sealing provided by two-step etch-and-rinse adhesives cannot be altered by the addition of an extra layer of the respective adhesive or the application of a more hydrophobic, non-solvated resin. MATERIAL AND METHODS full-crown preparations were acid-etched with phosphoric acid for 15 s and bonded with Adper Single Bond (3M ESPE...

BACKGROUND The degree of conversion (DC) of resin based materials depends, beside other factors, on the light-intensity applied during light curing. A lower DC might be correlated with an increased cytotoxicity of the respective materials. Therefore, aim of the present study was to investigate the influence of the distance between light-curing tip and adhesives on their cytotoxicity and degree ...

OBJECTIVE The aim of this study was to compare the shear bond strength of several self-etch adhesives to their two-step predecessors to ground and unground enamel. METHODS Seventy-five extracted, non-carious human third molar teeth were selected for this study. The buccal surfaces of each tooth were mechanically ground to obtain flat enamel surfaces (ground enamel), while the lingual surfaces...

BACKGROUND Suturing of perineal trauma after childbirth can cause problems such as pain, discomfort because of tight sutures, the need for suture removal, and dyspareunia. It is unclear whether leaving the perineal skin unsutured or using skin adhesives might prevent these problems. METHODS CENTRAL, MEDLINE, EMBASE, CINAHL, and prospective trial registers until January 2013 were searched for ...

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...

There is a push towards the use of renewable adhesives in particle board manufacturing industry. A remaining barrier for successful implementation carbohydrate-based necessity rapid cure behavior at lower temperatures (105–120 °C). The aim this work was to study effect highly reactive, bio-based 5-Hydroxymethylfurfural (HMF) on speed fructose-bishexamethylenetriamine (BHMT) adhesive. technologi...

The general topic of this review is protein-based underwater adhesives produced by aquatic organisms. The focus is on mechanisms of interfacial adhesion to native surfaces and controlled underwater solidification of natural water-borne adhesives. Four genera that exemplify the broad range of function, general mechanistic features, and unique adaptations are discussed in detail: blue mussels, ac...

abstract statement of problem: there is no enough published data about the shear bond strength of resin modified glass ionomer adhesives on caries-affected primary tooth dentin excavated using minimally invasive systems. objectives: to evaluate the shear bond strength of 2 different adhesives (one resin modified glass ionomer and one resin) using two caries removal techniques on healthy and car...
