Audiovisual analysis of exploring microbiology through the cultural lens

Abstract

The cultural bridge in the use of toothpastes with fluoride and xylitol in the reduction of Streptococcus mutans and the prevention of cavities is not clear. The antibacterial effect of pediatric toothpastes on Streptococcus mutans was compared. Each toothpaste was dissolved in different concentrations, and placed in Petri dishes with Streptococcus mutans ATCC 25175 and observed at 24 and 48 hours. The results show that there is variability in sensitivity depending on the concentration and exposure time. The toothpaste that had the greatest inhibitory effect on Streptococcus mutans was the one that had fluoride and xylitol.
