...by colony forming units counting (CFU/mg of dry biofilm and CFU/ml of suspension) and the morphological analysis of biofilms were performed using confocal laser scanning microscopy images and environmental scanning electron microscopy. Results: PACT (C at 2,5 mM and L at 48 J/cm2) presented a bacterial substantial reduction when compared with CHX treatment. The white light showed lethal photossensibilization in the utilized parameters. Conclu...
... meio da contagem de unidades formadoras de colônia (UFC/mg de biofilme seco e UFC/ml de suspensão) e análise morfológica dos biofilmes foram realizadas por meio de microscopia confocal a laser e microscopia eletrônica de varredura ambiental. Resultados: PACT (C a 2,5 mM e L a 48 J/cm2) apresentou a maior redução bacteriana substancial quando comparada a CHX. A luz branca apresentou fotossensibilização letal nos parâmetros utilizados. Conclusão: A utilização da curcumina, um corante natural e a luz branca, capaz de ativa...
...sive (1x/day) challenges. To perform the in situ stage, the samples were placed in removable intra-oral devices used by 12 volunteers Specimens were evaluated in profilometry (n=12), environmental scanning electron microscopy (ESEM) (n=12) and atomic force microscopy (AFM) (n=3) to evaluate the changes caused by fluoride on the surface of the dentin. The two-factor ANOVA for repeated measures showed that, after profilometric analysis, the sur...
...dia). Para realização da etapa in situ, as amostras foram posicionadas em dispositivos intra-orais removíveis utilizados por 12 voluntários. Os espécimes foram avaliados em perfilometria (n=12), microscopia eletrônica de varredura ambiental (MEV ambiental) (n=12) e microscopia de força atômica (AFM) (n=3) para avaliar as alterações causadas pelo fluoreto sobre a superfície da dentina. A ANOVA a dois critérios para medidas repetidas mostrou que o desgaste superficial foi afetado pelos tratamentos avaliados (p<0,001). O teste de T...
... (4x/day). For the abrasion model, specimens were subjected to daily brushing cycles (2x/day) with electric toothbrush with standard pressure (15s). Specimens were evaluated in Optical Profilometry (n=10) and Electron Microscopy Environmental Scan (n=3) in two distinct phases. Data from both phases were analyzed statistically. For evaluation by profilometer examination, analysis of variance for repeated measures ANOVA showed that all treatmen...
... abrasiva os espécimes foram submetidos a ciclos diários de escovação (2x/dia) com escova elétrica com pressão padronizada (15s). Os espécimes foram avaliados em Perfilometria óptica (n=10) e microscopia eletrônica de varredura ambiental (n=3) em duas fases distintas. Os dados de ambas as fases foram submetidos à análise estatística. Para a avaliação por perfilometria, a análise de variância ANOVA dois fatores para medidas repetidas mostrou que em todos os tratamentos a superfície dentinária foi afetada com o passar do tem...
