Effect of Propolis on Streptococcus mutans Counts: An in vivo Study

UNLABELLED: Propolis, a natural antibiotic, is a resinous substance that honey bees (Apis mellifera) produce. The main chemical classes present in propolis are flavonoids, phenolics and other various aromatic compounds. AIM: To evaluate the antibacterial action of propolis on the concentration of Streptococcus mutans colonizing the oral cavity of children. MATERIALS AND METHODS: Thirty children performed the rinses, with no other changes in their oral hygiene and dietary habits. Saliva was collected at two time points: Before using the product, 1 hour after the rinse. RESULTS: Paired t-test was used for analysis of the results. A reduction in the concentration of Streptococcus mutans was observed in samples collected after use of the extract. There was a reduction in Streptococcus mutans count when compared to samples obtained in baseline. Significant reductions were seen at the end of 1 hour. The result was statistically significant. There were no side effects in soft and hard tissues of mouth. Conclusion and clinical implication: The propolis possesses in vivo antimicrobial activity against Streptococcus mutans present in the oral cavity and might be used as a measure to prevent dental caries.
