Objectives: To evaluate the influence of the surface treatment and adhesive system on the shear bond strength and the failure mode of orthodontic brackets bonded to polymethylmethacrylate surfaces. Methods: Ninety metal brackets (n=15) were bonded to aged discs of polymethylmethacrylate SR Ivocron subjected to three ...
Objectives: To evaluate the immediate and water-aged microtensile bond strength of a universal adhesive to dentin, using the self-etch approach with and without an additional hydrophobic resin layer. Methods: Flat dentin surfaces were prepared from twelve non-carious human molars and were randomly divided into two g...
Objectivos: Determinar a influência de diversos sistemas adesivos sobre os valores de adesão de reparações imediatas de restaurações em compósito, após a preparação da superfície com abrasivos. Métodos: Foram testados 6 grupos. No G1 a superfície ...
Purpose: To evaluate the influence of the light curing protocol in the shear bond strength of a sealant to enamel treated with two self-etching adhesive systems, in salivar contamination conditions. Materials and Methods: The dental sealant (Delton, Dentsply) was applied, after saliva contamination, onto the vestibul...
Purpose: Evaluate the shear bond strength of a self-etching system to enamel pretreated with ozone and its type of fracture. Matherial and methods: Thirty sound bovine incisors were bisected and polished just before the application of the adhesive system. The adhesion area was limited to a 3-mm diameter. The specimens...
