Resumo: | Objective: To develop a material for denture relining and assess the microbiological and mechanical properties. The proposed liner was obtained through the incorporation of nanostructured silver vanadate (AgVO3) at 0, 1, 2.5, 5, and 10% polyethyl methacrylate (PEMA) containing plasticizer. Methods: Antimicrobial efficacy was evaluated by the Kirby Bauer agar method against Enterococcus faecalis, Pseudomonas aeruginosa, Candida albicans and Staphyloccocus aureus (n = 5); and mechanical properties were also assessed through roughness, such as Shore A hardness and tensile test. The results were analyzed by ANOVA and Tukey’s Multiple Comparison test (α = 0.05). Results: The material with AgVO3 at concentrations of 1% and 2.5% showed antimicrobial activity for E. faecalis, and 5% and 10% groups were effective for E. faecalis, P. aeruginosa and C. albicans. In the 5% group, hardness remained unchanged (p < 0.001). None of the tested concentrations significantly changed the roughness and the tensile strength (P > 0.05). Conclusion: Obtaining the material with antimicrobial potential promoted efficacy against E. faecalis, P. aeruginosa and C. albicans, kept the roughness property unchanged, did not change the adhesion property of the material to polymethyl methacrylate, and it maintained the hardness values compatible with resilient denture liners. |

O revestimento proposto foi obtido por meio da incorporação de vanadato de prata nanoestruturado (AgVO3) em 0, 1, 2,5, 5 e 10% de polimetilmetacrilato de metila (PEMA) contendo plastificante. Métodos: A eficácia antimicrobiana foi avaliada pelo método de Kirby-Bauer contra Enterococcus faecalis, Pseudomonas aeruginosa, Candida albicans e Staphyloccocus aureus (n = 5); e propriedades mecânicas como rugosidade também foram avaliadas por meio do teste de dureza Shore A e teste de tração. Os resultados foram analisados por ANOVA e teste de Tukey (α = 0,05). Resultados: O material com AgVO3 nas concentrações de 1% e 2,5% apresentou atividade antimicrobiana para E. faecalis, e 5% e 10% foram eficazes para E. faecalis, P. aeruginosa e C. albicans. No grupo de 5%, a dureza permaneceu inalterada (p < 0,001). Nenhuma das concentrações testadas alterou significativamente a rugosidade e a resistência à tração (P > 0,05). Conclusão: A obtenção do material com potencial antimicrobiano promoveu eficácia contra E. faecalis, P. aeruginosa e C. albicans, manteve a propriedade de rugosidade inalterada, não mudou a propriedade de adesão do material ao polimetilmetacrilato e manteve os valores de dureza compatível com revestimentos de reembasadores de dentadura resilientes.Universidade de São Paulo.
