Today's society demands socially committed professionals, therefore, trained in Social Responsibility.The University, faithful to its mission of integrally educating those who attend its classes, has to give an answer to this urgent need of people who consider their professional development within the commitment with others and their environment. This paper is Francisco de Vitoria University’s proposal about this issue, presenting it as an university mandatory course. More than ten years of experience and achievements bases on this pioneer initiative, endorse this bid in favour of the university student’s education in Social Responsibility

PASHLEY3, 1University of Hong Kong, Hong Kong SAR, China, 2Osaka University, Japan, 3Medical College of Georgia, Augusta, USA  This study compared the microtensile bond strength (µTBS) and the ultrastructure of resin-dentin interfaces of four self-etching systems that were applied to dentin with thick smear layers. Human third molars were ground with 180-grit SiC papers to expose deep coronal dentin. A 3-mm vertical slit was made along the diameter of each tooth to fit a glass cover slip, dividing each tooth into two bonding surfaces. Two two-step, self-etching primers (ABF experimental system, Kuraray and Imperva Fluoro Bond, Shofu) and two single-step, self-etching adhesives (One-Up Bond F, Tokuyama and AQ Bond, Sun Medical) were examined. Adhesives were applied to one side of the teeth passively, and to other side with continuous agitation for the same self-etching period. Incremental composite buildups were performed and beams with cross-sectional areas of 0.81mm2 were prepared for µTBS evaluation. Demineralized, bonded specimens were processed for TEM examination. Two-way ANOVA showed that both the adhesive type and the application mode significantly affected µTBS results. However, the interaction of these two factors was not statistically significant (P>0.05). For each adhesive, agitation produced significantly higher µTBS than passive application. With passive application, all systems diffused through thick smear layers and formed thin hybrid layers in intact dentin. With continuous agitation, smear layers were completely dispersed or dissolved, and thicker hybrid layers with upstanding collagen fibrils were observed. It is concluded that bonding of mild self-etching primers/adhesives to dentin with clinically relevant, thick smear layers may be improved by continuous agitation during the self-etching process.
