OBJECTIVE: The objective of this study was to evaluate the antimicrobial activity of Mineral trioxide aggregate e Portland cement against some selected cariogenic bacteria. METHODS: Wells were made of approximately 0.5 mm in diameter, in solid culture media and immediately filled with cement. Twelve samples of each material were obtained for the realization of the agar diffusion method. These samples were tested with Streptococcus mutans (ATCC 700610), Enterococcus faecalis (ATCC 29212), Lactobacillus acidophilus (UFV) and Lactobacillus casei (UNICAMP). Petri plates containing Tripticase soy Agar (TSA) were used for the growth of Streptococcus mutans and Enterococcus faecalis, and plates of Man Rogosa & Sharpe Agar (MRS) for the Lactobacillus acidophilus and Lactobacillus casei. After 48 hours of incubation, it was made the measurement of inhibition halos with the aid of manual caliper. RESULTS: The diameters obtained to MTA (2.50 ± 0.00; 2,92 ± 0.63; 2.58 ± 0.38), PC (1.17 ± 0.29; 2.00 ± 0.43; 1.33 ± 0.14) and calcium hydroxide cement (3.83 ± 0.29; 3.00 ± 0.00 ± 2.58 ± 0.72) were expressed in millimeters and subsequently submitted to Tukey test (p<0.05). CONCLUSION: According to the results obtained, it was concluded that the MTA and Portland cement showed to have similar antimicrobial properties, however these were not effective against the Enterococcus faecalis.

Streptococcus mutanspredominantly creates an acidic environment in an oral cavity. This results in dental demineralization and carious lesions. The probiotics are beneficial microorganisms that modulate the bacterial balance in the digestive system. Prebiotics are defined as nondigestible oligosaccharides that are utilized for the selective stimulation of the beneficial microorganisms. The objective of this study was to evaluate the efficacy of the prebiotics, galactooligosaccharides (GOS) and fructooligosaccharides (FOS), for enhancing the probioticLactobacillus acidophilusATCC 4356, for inhibitingStreptococcus mutans(A32-2) for the prevention of dental caries. The growth rate of theS. mutanssignificantly decreased when cocultured withL. acidophilusin the GOS-supplemented medium at 3%, 4%, and 5%. In the FOS-supplemented medium, the growth rate ofS. mutanssignificantly decreased in all concentrations when cocultured withL. acidophilus. There was no significant difference in the growth rate ofL. acidophilusin all concentrations of either GOS or FOS. It can be concluded that the growth rate ofS. mutanswas significantly retarded when cocultured withL. acidophilusand the proper concentration of prebiotics. These prebiotics have potential for a clinical application to activate the function of the naturally intraoralL. acidophilusto inhibitS. mutans.

ABSTRACT Objective:The aim of this study was to assess the antimicrobial potency of aqueous extract of Psidium guajava leaves in two different concentrations as a toothbrush disinfectant against three oral bacterial species.Materials and Methods: Aqueous extracts of P. guajava leaves were prepared at 20% and 30% concentrations and 0.2% chlorhexidine was used as control. The toothbrushes were equally divided into 9 groups with 10 toothbrushes per disinfectant, which were contaminated with Streptococcus mutans, Lactobacillus acidophilus, and Enterococcus faecalis. Microbial culture was done after 5 min and 3 h of decontamination.Results: Group Ia and Ib showed that the presence of E. faecalis was observed in 8 (40%) of 20 toothbrushes. Group IIa and IIb showed a significant reduction in colony forming unit/toothbrush during 3 h evaluation. Group IIIa and IIIb showed nil growth during 3 h evaluation. Nil growth was observed with the control group for all three organisms. Statistically significant values were obtained for 5 min (P < 0.001) and 3 h (P < 0.001) disinfection period against L. acidophilus at two different concentrations.Conclusion: Aqueousextracts of guava leaves can be used as an alternative organic product for disinfection of toothbrushes.
