ABSTRACT

Objective: The purpose of this in vitro study to evaluate antimicrobial efficacy of commercially available herbal dentifrices in comparison with conventional dentifrices against seven oral microbes, namely, Streptococcus mutans, Streptococcus mitis, Streptococcus sanguinis, Streptococcus salivarius, Actinomyces viscosus, Candida albicans, and Lactobacillus acidophilus. Materials and methods: Antimicrobial properties of dentifrices were evaluated by measuring zone of inhibition at 48h on blood agar plates inoculated with microbial strains, using disc diffusion method. Each dentifrice was tested in 100% and 50% concentration. Sterile distilled water was used as control. One way Analysis of Variance followed by Tukey post hoc was used for multiple group comparisons. P value < 0.05 was considered statistically significant. Results: In both, 100% and 50% concentrations maximum zone of inhibition was observed with Smyle™ herbal toothpaste followed by Himalaya herbals™ dental cream. Conclusion: Antimicrobial activity of Smyle™ herbal toothpaste is the best against microorganisms tested in present study.


Objetivo: O propósito deste estudo foi avaliar e comparar a eficácia antimicrobiana de dentifrícios herbaiscomerciais e convencionais contra sete micro-organismos: Streptococcus mutans, Streptococcus mitis, Streptococcus sanguinis, Streptococcus salivarius, Actinomyces viscosus, Candida albicans, and Lactobacillusacidophilus. Materiais e métodos: Propriedades antimicrobianas dos dentifrícios foram avaliadas a partir damedição da zona de inibição utilizando o método de difusão em disco após 48h em placas de ágar sangue inoculadascom as cepas microbianas. Cada dentifrício foi testado nas concentrações de 100% e 50%. O controleconsistiu em água destilada estéril. As comparações entre grupos foram realizadas por ANOVA a um critério eteste de Tukey post hoc, ambos com nível de significância de 5%. Resultados: Em ambas as concentrações de100% e 50%, a zona de inibição máxima foi observada para o dentifrício herbal Smyle® seguido do dentifrícioherbal Himalaya herbals®. Conclusões: O dentifrício herbal Smyle® apresentou o melhor resultado contra osmicro-organismos avaliados no presente estudo.
