The aim of this study was to establish effect of 14 day consumption of commercially available yoghurt containing Lactobacillus rhamnosus ATCC53103 - LGG (Bioaktiv LGG, Dukat, Croatia) on Streptococcus mutans and Lactobacillus spp. salivary counts in children. Twenty five patients, 6-10 yr old participated in the study. At the inclusion in the study caries risk for every patient was evaluated. T...

objectives : the present study was designed to evaluate the changes in saliva properties and oral microbial flora in patients undergoing fixed orthodontic treatment. materials and methods: two important saliva properties namely the salivary flow rate and ph as well as oral microbial flora were assessed in 30 orthodontic patients before starting fixed orthodontic treatment and after six, 12 and ...

s: Background and Objectives: This in vitro study was designed to evaluate and compare the antimicrobial effects of extracts of Neem sticks, Tulsi leaves and Triphala against Streptococcus Mutans and Lactobacillus Acidophilus.Materials and Methods: Sterile solutions of 10% & 25% concentrations were prepared from Neem, Tulsi and Triphala extracts. After growing on culture plates micro-organisms ...

Probiotics have been demonstrated as a new paradigm to substitute antibiotic treatment for dental caries, gingivitis, and chronic periodontitis. The present work was conducted to compare the characteristics of oral care probiotics: Weissella cibaria CMU (Chonnam Medical University) and four commercial probiotic strains. Survival rates under poor oral conditions, acid production, hydrogen peroxi...

BACKGROUND The purpose of this investigation was to evaluate the effect of probiotic lactobacilli on Streptococcus mutans (MS) and multispecies biofilms isolated from children with severe caries. MATERIAL AND METHODS Twenty children with active caries (DMFS ≥6) were selected as the experimental group and Streptococcus mutans (MS) were isolated from their saliva. After identification the MS stra...

Indigenous beers (chicha) are part of the indigenous culture in Ecuador. The fermentation process of these beers probably relies on microorganisms from fermented substrates, environment and human microbiota. We analyzed the microbiota of artisanal beers (including a type of beer produced after chewing boiled cassava) using bacterial culture and 16S ribosomal RNA (rRNA) gene-based tag-encoded FL...

The antimicrobial activity of clove and clove bud oil were investigated by agar well diffusion method against five dental caries causing microorganisms namely Streptococcus mutans, Staphylococcus aureus, Lactobacillus acidophilus (bacteria), Candida albicans and Saccharomyces cerevisiae (yeast). The results indicated that clove and clove oil have a potent antimicrobial activity against the test...

The hexane,ethyle acetate and methanolic extracts of Nymphaea nauchali. were evaluated for antimicrobial activity against clinically important bacteria viz. Staphylococcus aureus(MTCC 3160), Pseudomonas aeruginosa (ATCC9027), Bacillus subtilis (ATCC 6633), Escherichia coli (ATCC 35218), Enterococcus faecalis (MTCC 439), Xanthomonas campestris (MTCC 2286), Streptococcus mutans (MTCC 497), Lactob...

BACKGROUND/AIMS Lactobacilli are known to play an important role in the maintenance of health by stimulating natural immunity and contributing to the balance of microflora. However, their role in chronic periodontitis is unclear. We aimed to identify oral lactobacilli in chronic periodontitis and periodontally healthy subjects, and to determine their antimicrobial activity against putative oral...

OBJECTIVES To investigate the effect of triclosan exposure on the antimicrobial susceptibilities of numerically important dental bacteria. METHODS A gradient plate technique was used to expose Fusobacterium nucleatum, Lactobacillus rhamnosus, Neisseria subflava, Porphyromonas gingivalis, Actinomyces naeslundii, Prevotella nigrescens, Streptococcus oralis, Streptococcus sanguis, Streptococcus ...
