14. Screening and identification of bacteriocin-like inhibitory substances producing lactic acid bacteria from fermented products
Abstract A total of 544 isolates of lactic acid bacteria isolated from fermented products: 451 isolates from fermented products from Thailand and 93 isolated from French fermented products were screened for bacteriocin production. 10 isolates showed antimicrobial activities. Identification of the selected strains by random amplification of polymorphic DNA-po

16. Adhesiveness of bulk-fill composite resin in permanent molars submitted to Streptococcus mutans biofilm
Abstract: The aim of the present study was to evaluate the microtensile bond strength and the microleakage of a bulk-fill composite resin compared with a conventional incremental composite resin, in permanent molars and under cariogenic challenge using a Streptococcus mutans model. Permanent human third molars (n = 60) with an occlusal cavity of 5×3×2 mm w

17. Antibacterial and Cytotoxic Potential of a Brazilian Red Propolis
Abstract Objective: To evaluate in vitro the effect of a red propolis ethanolic extract (RPE) in the prevention of growth of a cariogenic biofilm and its cytotoxic potential. Material and Methods: Minimum inhibitory and bactericidal concentrations (MIC and MBC) of RPE against Streptococcus mutans and Lactobacillus casei were determined. The cytotoxic poten

18. Role of Candida albicans on enamel demineralization and on acidogenic potential of Streptococcus mutans in vitro biofilms
Abstract There is growing evidence that C. albicans is associated with dental caries, but its role on caries development needs to be better clarified. Objective: To evaluate at the hard tissue level the effect of C. albicans on the cariogenic potential of S. mutans biofilms focusing on the mineral profile of induced carious lesions. This study also aimed to

23. Effect of Bulgarian propolis on the oral microflora in adolescents with plaque-induced gingivitis
ABSTRACT We compared the effect of two therapeutic approaches (marketed toothpaste and addition of Bulgarian propolis extract to the toothpaste) on gingival inflammation, plaque formation and oral microbial flora on Bulgarian adolescents with moderate plaque-induced gingivitis. The participants were divided randomly into two groups of 35 students. The first
