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...

Objective: To evaluate the influence and effectiveness of the salivary decontamination protocol after polymerization of a universal adhesive on dentin adhesive strength, after 24 hours and 6 months of ageing. Methods: Fifty intact molars were sectioned in order to obtain two slices of dentin from each tooth. In all...

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 ...

Introduction: Saliva contamination during the bonding procedure is a common cause of bracket bond failure. By combining acid and primer in one component, self-etching primers (SEP) reduce the working time and the risk of contamination. Objectives: The purpose of this study was to investigate the effect of saliva conta...

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...
