Introduction: It is known that self-etching adhesive systems can act as semi-permeable membranes. Objective: Evaluate the effects of additional layer of hydrophobic resin on the microtensile bond strength of self-etching one-bottle adhesives. Material and method: Sixty bovine incisors were used in this study. The facial enamel surfaces of the crowns were abraded with silicon carbide paper to expose flat, mid-coronal dentin surfaces. The following adhesives were used: Clearfil Tri S Bond (CTSB), AdheSE One (ADH) and One Coat 7.0 (OC). Each material was tested with and without applying an additional layer of hydrophobic material from the same manufacturer. Z-350 composite resin was inserted in three 1 mm increments. All adhesive restorative procedure was performed under simulated pulpal pressure and the microtensile test was performed immediately after curing the composite resin. Data were submitted to ANOVA and Tukey test (p < 0.05). Result: For all adhesives tested, the worst results were observed in groups which the additional layer of hydrophobic resin was not applied. Conclusion: The application of additional layer of hydrophobic material can improve the adhesion of self-etching all-in-one adhesive systems.

At present, the processes of medicalization of childhood have reached the school spaces where diagnostic labeling accompanied of prescription of psychotropic drugs proliferate. The present work aims to study through the Foucauldian genealogical approach, the process of medicalization of education, with a special attention to analysis of Brazilian bills which serve to the medicalization logics and to the study of resistance movements which emerged with the purpose of denouncing psychopathology-causing strategies. It is considered that the school spaces, subject to the disciplining processes and standardization of bodies, have gained through bills, new devices of support to the psychiatric discourses. These, by appropriating of the childhood considered problem, have spawned diagnoses and psychopharmacological drugs, process that has been faced by resistance movements identified with proposals for enhancement of the plurality of life.
