ABSTRACT

WHO and FDI have ruled that 60-90% of schoolchildren are affected by caries. In our country, the System of Epidemiological Surveillance of Oral Pathologies (SIVEPAB) (SIVEPAB) 2012. Report a rate of 85% of caries nationally in pediatric population. Anticariogenic diamino agents such as silver fluoride are an encouraging decrease in treatment for these high rates of tooth decay in our country, this agent can act as bactericidal or bacteriostatic based on their concentration and their ability to inhibit endogenous metalloproteinase (MMP-2, 8, 9). Problem: What will be the bactericidal effectiveness of silver diamine fluoride different concentration on cariogenic Streptococci saliva samples taken from school and dentin? Objective: Determine the bactericidal effectiveness Silver diamine fluoride (SDF) to different concentration on bacterial growth of Streptococcus mitis, S. mutans, and S. salivarius in saliva samples and dentin in school. Material and methods: An experimental study was conducted as an independent variable the bactericidal effect of silver diamine fluoride was taken as dependent inhibition halo. Descriptive measures were used as a comparison test and analysis of variance using Post-hoc Tukey with 95% confidence, and exploratory data analysis. Results: One hundred samples, of which 48.3% corresponded to S. mutans, 41.4% to S. salivarius and 10.3% to S. mitis, were analyzed, we obtained a larger zone of inhibition for all three organisms at 38% showing a statistically significant difference from 12% (p ‹ 0.05). It was also observed that the 12% sample bacteriostatic effect, not to the concentration of 38% was found a bactericidal effect. Conclusion: Our results suggest that 38% concentration has a bactericidal effect on Streptococcus viridans group and 12% showed not recommended for the arrest or detention of dentine caries bacteriostatic effect.
