BACKGROUND Ethnomedicine is gaining admiration since years but still there is abundant medicinal flora which is unrevealed through research. The study was conducted to assess the in vitro antimicrobial potential and also determine the minimum inhibitory concentration (MIC) of Citrus sinensis peel extracts with a view of searching a novel extract as a remedy for dental caries pathogens. MATERI...

Purpose: To assess and compare the invivo antibacterial property of Miswak sticks and 0.5% Sodium Fluoride (NaF) impregnated Miswak sticks against Streptococcus mutans (S.mutans) and Lactobacillus. Materials and methods: A randomized controlled clinical trial (parallel group design) was conducted involving 20 subjects who were randomly allocated to Group A (0.5% NaF impregnated Miswak sticks) a...

AIM To compare the antimicrobial effect of 2% chlorhexidine, 2.5% sodium hypochlorite and MUMS containing 2% chlorhexidine. MATERIALS AND METHODS All of the above irrigants were examined on Enterococcus faecalis, Streptococcus mutans, Candida albicans, Lactobacillus casei and E. coli. A total of 0.5 CC of each solution and 0.5 CC of McFarland solution bacterium were added to each examination ...

This work used the broth microdilution method to investigate the antimicrobial activity of the essential oil obtained from the leaves of Plectranthus neochilus (PN-EO) against a representative panel of oral pathogens. We assessed the antimicrobial activity of this oil in terms of the minimum inhibitory concentration (MIC). PN-EO displayed moderate activity against Enterococcus faecalis (MIC = 2...

The dental plaque harbours a diverse range of bacteria such as Streptococcus mutans, Streptococcus sanguis, Streptococcus sobrinus, Lactobacillus spp, Actinomyces spp. etc, embedded in a matrix of polymers of bacterial and salivary origin. Therapeutic procedures used in the treatment of caries do not always eliminate all the microorganisms in the residual tissues, leading to development of recu...

alcoholic extract of rosemary on oral bacteria, compared to a commercially available herbal dentifrice. Standard strains of Streptococcus mutans (ATCC 25175), Streptococcus oralis (ATCC 9811) and Lactobacillus rhamnosus (ATCC 7469) were used, as well as different toothpastes based on rosemary (TR), on propolis (TH), triclosan (positive control) (TPC) and non-fluoridated dentifrice (negative con...

background and objectives: dental caries, caused by oral microbial flora, is considered as one of the most common infectious diseases in human. the aim of this study was to determine the effect of short-term consumption of probiotic yogurt containing bifidobacterium lactis on salivary streptococcus mutans and lactobacilli in students with initial stages of dental caries. materials and methods: ...

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 1...

Saliva may provide us with clues for the evaluation of dental caries susceptibility and dental caries risk. The aim of this study was to compare salivary parameters: flow rate, pH, buffering capacity, glucose in saliva and bacterial count of Streptococcus Mutans and Lactobacillus in healthy and suffering from DM1 children and adolescents in Plovdiv region. The study was conducted on 128 childre...

The aim of this study is to analyze ozone impact on some cariogenic bacteria in ex vivo and in vitro conditions. The in vitro part of study inoculated dentine with strains of Streptococcus mutans ATCC 33402 and Lactobacillus paracasei ATCC 11974 bacteria. Samples of dentine before and after 40s ozone treatment were collected and anaerobically incubated. Samples of cariogenic dentine (N = 24) we...
