INTRODUCTION Diabetes is associated with higher rates of caries, on the other hand some studies have shown that renal failure can be protective against dental caries. OBJECTIVES In this study we compared oral Lactobacillus and Streptococcus mutans between diabetic dialysis and non-diabetic dialysis patients and the normal population. PATIENTS AND METHODS During November 2014 to January 2014...

Introduction and objective: Dental caries is a common oral bacterial pathology that has been associated with Streptococcus spp., mainly Streptococcus mutans and Lactobacillus spp. Antibacterial activities of Terminalia chebula extracts against several bacterial strains have been reported. The aim of this study was to evaluate the possible antimicrobial potential of T. chebula fruit extracts (ac...

Streptococcus mutans (S. mutans), harboring biofilm formation, considered as a main aetiological factor of dental caries. Gtf genes play an important role in S. mutans biofilm formation. The purpose of this study was to investigate the effect of Lactobacillus acidophilus-derived biosurfactant on S. mutans biofilm formation and gtfB/C expression level (S. mutans standard strain ATCC35668 and iso...

objective: punica granatum has been used for many years in folk medicine due to several purposes. the aim of the present study was to evaluate the effect of methanolic extract of punica granatum peel (mepgp) against streptococcus mutans, staphylococcus aureus, streptococcus salivarius, streptococcus sanguinis, staphylococcus epidermidis, actynomyces viscosus, lactobacillus acidophilus and candi...

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 sam...

background: green tea contains phenolic compounds which could be considered as an anticariogenic agent. in addition, there has not been any significant side effect reported compared to sodium fluoride. so it seems that any comparison between the effects of green tea extract on the level of cariogenic bacteria with sodium fluoride is beneficial. the purpose of this study was to compare the effec...

Although Streptococcus mutans has been implicated as a major etiological agent of dental caries, our cross-sectional preliminary study indicated that 10% of subjects with rampant caries in permanent teeth do not have detectable levels of S. mutans. Our aims were to use molecular methods to detect all bacterial species associated with caries in primary and permanent teeth and to determine the ba...

Dental caries is a biofilm-dependent oral disease and Streptococcus mutans is the known primary etiologic agent of dental caries that initiates biofilm formation on tooth surfaces. Although some Lactobacillus strains inhibit biofilm formation of oral pathogenic bacteria, the molecular mechanisms by which lactobacilli inhibit bacterial biofilm formation are not clearly understood. In this study,...

STATEMENT OF THE PROBLEM Dental caries is the most common disease of childhood. Using probiotics has recently been introduced to reduce the incidence of dental caries.It consists of live microbial food supplements that beneficially affect the host, and hence are considered an alternative way to eradicate the infections. PURPOSE The aim of this study is to evaluate the effect of consumption of...

background: the aim of this in vitro study was to assess antimicrobial efficacy of acacia nilotica, murraya koenigii (l.) sprengel, eucalyptus hybrid , psidium guajava extracts, and their combination on streptococcus mutans and lactobacillus acidophilus. materials and methods: the branches of four plants were collected, identified, and authenticated by a taxonomist. the plants were rinsed in wa...
