INTRODUCTION Many essential oils have been advocated for use in complementary medicine for bacterial and fungal infections. However, few of the many claims of therapeutic efficacy have been validated adequately by either in vitro testing or in vivo clinical trials. OBJECTIVE To study the antibacterial activity of nine commercially available essential oils against Streptococcus mutans in vitro...

In the last years, researches developed with biosurfactants for application in the medical area have been revealing the promising biological activities of these biomolecules. In this work the antimicrobial and anti-adhesive properties of a biosurfactant Rufisan isolated from the yeast Candida lipolytica UCP 0988, growth in a medium supplemented with ground nut refinery residue was determined ag...

OBJECTIVE Dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. This study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such diseases. MATERIALS AND METHODS Saponins were extracted from Bauhinia purpurea, Madhuca longif...

white spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. long-lasting antibacterial properties of orthodontic cements can reduce this phenomenon. the aim of this research was to compare antimicrobial activity of three commercial glass ionomer cements with three commercial zinc phosphate cements, over time, against streptococcus mutans and candida albicans. dir...

Streptococcus downii is a recently reported bacterial species of oral origin, with inhibitory capacity against mutans, Actinomyces naeslundii, Veillonella parvula and Aggregatibacter actinomycetemcomitans, which confers upon it the potential being an probiotic. The aim present study was to identify mechanisms by S. exerts its effect on mutans. To this end, assessed consumption glucose proteins ...

BACKGROUND Early childhood caries (ECC) is an aggressive condition that can affect teeth of young children. This study aimed to evaluate genotypic diversity and phenotypic traits of S. mutans isolated from dental biofilms of children with different caries status in comparison with caries free (CF) children. METHODS Streptococcus mutans strains were isolated from supragingival biofilm samples ...
