The goal of this pilot study was to evaluate the effects of an antimicrobial additive (Microban) to toothbrushes on residual retention of periodontal pathogens. METHODOLOGY: Twenty patients had one side of their mouths brushed with a toothbrush containing the antimicrobial agent (experimental side), and the other side with a toothbrush containing no agent (control). Toothbrushes were air-dried (25 degrees C) for four or 24 hours. Toothbrush heads were vortexed and cultured for Prevotella species (Ps), Porphyromonas gingivalis (Pg), Actinobacillus actinomycetemcomitans (Aa), and non-specific colony-forming units (NS). The plates were incubated and counted. Means and standard deviations were calculated, and data were analyzed using a series of t-tests (paired and unpaired) and Wilcoxon matched-pairs signed-rank test. RESULTS: No significant inter- or intra-group differences in mean counts were found; however, when four-hour and 24-hour data for Aa, Pg, or NS were combined, experimental counts were lower than controls in 39/50 (78%) of the matched pairs (Wilcoxon signed-rank test p = 0.01). CONCLUSION: Toothbrushes containing the antimicrobial additive showed lower microbial counts than those without, but between-group means were not statistically significant.
