Streptococcus mutans serotype E is a major bacterium causing caries, and widely present in dental plaque. Dentifrices containing xylitol have been shown to inhibit the growth of these mutans streptococci. The aim of the study was to identify the influence of dentifrice containing xylitol on S. mutans serotype E (in vitro). The 1:1 solution of dentifrice containing xylitol was diluted to the test concentrations of 100%, 10%, 1%, 0.1%, 0.01%, and 0.001%, in addition to positive and negative control groups. These solutions were examined in S. mutans serotype E test cultures by the diffusion method. The resulting inhibition zone was 2.16 mm at a concentration of 10%, and 3.0 mm at a concentration of 100%. Zero zone size was found at all other test concentrations, and a significant (Spearman) negative correlation was indicated between the concentration of dentifrice and the growth of mutans streptococci (p<0.05). The MIC was not been identified, but MBC was 10%. In conclusion, the dentifrice containing xylitol can significantly inhibit the growth of S. mutans serotype E at least at dentrifice concentrations of 5-10%.

Streptococcus mutans serotype C is a major causative agent to caries and is found predominantly in dental plaque and saliva. Dentifrice containing xylitol has been shown to inhibit the growth of mutans streptococci. The aim of the study was to identify in vitro the influence of dentifrice containing xylitol on S. mutans serotype C. The solution of dentifrice containing xylitol was first diluted with sterile aquadest at 1:1, and then to concentrations of 100%, 10%, 1%, 0.1%, 0.01%, and 0.001%, also with positive and negative controls. These solutions were exposed to S. mutans Serotype C by diffusion and dilution method. The results of the study show that the inhibition zone formed at concentration of 10% and 100%. There was a significant positive correlation between the concentration of dentifrice and the growth of mutans streptococci (p<0.05), with MBC point at 10%. In conclusion, dentifrice containing xylitol has an antibacterial effect and can inhibit the growth of S. mutans serotype C. Increasing concentration of dentifrice containing xylitol increases the size of the inhibition zone.

Abstrak :
The Psidium guava Linn leaf extract as mouthrinse has been suggested to be used against toothache, and also has suggested effect against diarrhea and vomitting, as well as anti spasmodic and rheumatic symptoms, anti inflammation, anti piretic, analgetic, and anti bacterial activity. However, to consider potential side effects, this work aimed to test the acute toxicity of guava leaf extract. For this purpose guava leaf extract was given orally to groups of ten mice each at a doses of 1.25g, 2.5, 5, 10 and 21 g/kg body weight in a suspension with CMC Na 0,5%. Ten mice were used as control with a dose of 1 ml CMC Na 0,5%. The results suggest no acute toxicity to mice, since even the biggest dose given (show no measurable) value of LD 50. It could be concluded that guava leaf extract shows no acute toxicity to mice at tested concentrations.
