INTRODUCTION: The occurrence of stomatitis is common since the surface characteristics of the dentures may act as reservoirs for microorganisms and have the potential to support biofilm formation. PURPOSE: To assess the surface properties (wettability/roughness) and color stability of an acrylic resin combined with the antimicrobial polymer poly (2-tert-butylaminoethyl) methacrylate (PTBAEMA). MATERIAL AND METHOD: Thirty disc-shaped specimens of an acrylic resin (Lucitone 550) were divided into three groups: 0% (control); 5% and 10% PTBAEMA. Surface roughness values (Ra) were measured using a profilometer and wettability was determined through contact angle measurements using a goniometer and deionized water as a test liquid. Color data were measured with a spectrophotometer. Kruskal-Wallis and Dunn's test were used to compare roughness values. Wettability data were analyzed using ANOVA and Tukey's test. Color data were compared using the Student's t-test and ∆E values were classified according to the National Bureau of Standards (NBS). All statistical analyses were performed considering α=.05. RESULT: Significant differences (p<.05) were detected among the groups for roughness, wettability and color stability. According to the NBS, the color changes obtained in the 5% and 10% PTBAEMA groups were "appreciable" and "much appreciable", respectively. CONCLUSION: It could be concluded that PTBAEMA incorporation in an acrylic resin increased the roughness and wettability of surfaces and produced color changes with clinical relevance.

The aim of this study was to investigate the surface properties of polymeric composites and the osteoblastic cell behaviour set in direct contact with the biomaterials tested. The surface properties were evaluated before and after 6-month incubation in an in vitro environment. The composite materials were prepared by means of extrusion and injection moulding. Three commercially available thermoplastic polymers (ABS (poly)acrylonitrile butadiene styrene) were used as composite matrices. Antibacterial silver nanoparticles (AgNPs) were added as a modifying phase. Surface properties of the materials tested, such as: wettability, roughness and microstructure, were determined. Furthermore the morphology of Saos-2 human osteoblastic cells in direct contact with the composite materials was assessed after the 7-day culture. The addition of silver nanoparticles caused minor changes in the wettability and roughness values. As light modification, the silver nanoparticles influenced the microstructure. The osteoblasts displayed the proper morphology and they evenly settled on the surface of the pure polymer and composite materials, which indicated the material cytocompatibility.
