ResumoO presente estudo tem como objetivo apresentar os resultados preliminares relacionados a atividade antimicrobiana de uma solução atividade antimicrobiana das mesmas foi testada por meio da determinação da concentração inibitória (CIM) e bactericida/fungicida mínimas (CBM/CFM) frente aos microrganismos Staphylococcus aureus (S. aureus, gram positivo), Pseudomonas aeruginosa (P. aeruginosa, gram negativo) e Candida albicans (C. albicans, levedura), separadamente. Após realização do teste de microdiluição em caldo, em duplicata, o solvente LSS demonstrou o melhor resultado com MIC de 1,25mg/ml para P. aeruginosa, 0,039mg/ml para S. aureus e 0,078mg/ml para C. albicans. Os resultados para CBM/CFM encontrados foram: 1,25mg/ml para P. aeruginosa, 0,039mg/ mais adequado, toxicidade e efeito sobre os materiais utilizados em próteses dentárias, como resina acrílica.

Objectives: This study aimed to evaluate in vitro the effects of mechanical brushing with Punica granatum Linné (P. granatum L.) or pomegranate on the mass, roughness and color of artificial teeth in acrylic resin. Methods: The artificial teeth (n=30) were randomly distributed into 3 groups, according to the tested solution (n = 10 each group): Distilled Water (DW), Commercial Dentifrice (CD) and Dentifrice based on P. granatum L. (PD). All the samples were brushed for a simulated 5-year period. The effects of mechanical brushing were evaluated before brushing and after 12, 24, 36 and 60 months. Data were submitted to the Kolmogorov-Smirnov test and a significance level of 5% was adopted and compared by ANOVA with Bonferroni. Results: In the PD group, the mass changed was statistically significant at T4 (0.3942 ± 0.003g). The roughness was altered only in T4 in the PD group (1.059 ± 0.053), while in the CD group was altered in T1 (0.982 ± 0.026) and T2 (0.965 ± 0.02) and finally the color changes were only detected in the PD group in T4 (2,899 ± 0.992), while in the DW group (2,050 ± 0,287 *) and common dentifrice (2,710 ± 0,228*) in T3.
Conclusion:The pomegranate dentifrice did not cause deleterious effects on the surface of artificial acrylic resin teeth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
