Brief Summary

Given that the participation of oral microorganisms in the development of the most prevalent pathologies of the oral cavity is unquestionable, efforts have been made to create agents that allow controlling these bacteria. The objective of this work was to analyze the antibacterial effect of green tea infusion used as a mouthwash on saliva and bacterial plaque. The green tea infusion was prepared at 13% at approximately 90 ° C, being the same applied to 14 participants from the 1st to the 5th grade (experimental group); and to other 14 participants the placebo was applied (control group). The antibacterial effect was determined by counting the colony forming units (CFU) in the cultures of samples of bacterial plaque and saliva, taken before the application of the infusion and immediately after.

Outcome Measures

Primary Outcomes (3)

  • Bacterial plaque Stage 1 (Before intervention)

    The measure was done with the count of Colony forming units

    thorough study completion, an average of 24 hours

  • Bacterial plaque Stage 2 (After intervention)

    The measure was done with the count of Colony forming units

    1 minute after mouthwash use

  • Antimicrobial effect

    The measure was done with the difference in count of Colony forming units before and after intervention

    up to 24 hours, thorough study completion
