ABSTRACT

The purpose of this study was to investigate the antimicrobial effect of a Punica granatum Linn (pomegranate) phytotherapeutic gel and miconazole (Daktarin® oral gel) against three standard streptococci strains (mutans ATCC 25175, sanguis ATCC 10577 and mitis ATCC 9811), S. mutans clinically isolated and Candida albicans either alone or in association. The effect of minimum inhibitory concentrations of the gels on the adherence of these microorganisms to glass was assessed in the presence of 5 percent sucrose, using increasing and doubled concentrations of the diluted solution of the gels ranging from 1:1 to 1:1024. The minimum inhibitory concentrations of adherence of Punica granatum L. gel against the test organisms were: 1:16 for S. mutans (ATCC), S. mutans (CI) and S. sanguis; 1:128 for S. mitis and 1:64 for C. albicans. The minimum inhibitory concentrations of adherence of miconazole against the same organisms were: 1:512, 1:64, 1:4, 1:128 and 1:16, respectively. In experiments with three and four associated microorganisms, the Punica granatum L. gel had greater efficiency in inhibiting microbial adherence than the miconazole. The results of this study suggest that this phytotherapeutic agent might be used in the control of adherence of different microorganisms in the oral cavity.


O propósito deste estudo foi investigar a concentração inibitória mínima de aderência (CIMA) de três linhagens de estreptococos (mutans ATCC 25175, sanguis ATCC 10557 e mitis ATCC 9811), S. mutans isolado clinicamente e de cepas de Candida albicans, separadamente ou associadas, frente a um gel fitoterápico obtido da Punica granatum Linn. (romã) e ao agente antifúngico miconazol (Daktarin® gel oral). A concentração inibitória mínima de aderência das bactérias ao vidro foi determinada na presença de sacarose a 5 por cento, usando-se concentrações crescentes e dobradas da solução diluída do gel variando de 1:1 a 1:1024. Os valores de inibição do gel fitoterápico foram de 1:16 para S mutans (ATCC), S. mutans (IC) e S. sanguis; 1:128 para S. mitis e 1:64 para C. albicans. Sobre as mesmas linhagens, as concentrações inibitórias mínimas de aderência do miconazol foram: 1:512, 1:64, 1:4, 1:128, 1:16 respectivamente. O gel da romã apresentou maior eficácia sobre associações de três e quatro microrganismos do que o gel do miconazol. Os achados deste estudo sugerem o emprego desse agente fitoterápico pode ser uma opção no controle da aderência dos microrganismos testados na cavidade bucal.
