Dental caries is an infectious disease which still constitutes a public health concern. It begins at an early age and is caused mainly Streptococcus mutans (S. mutans). The aim of this study was to characterize the salivary humor immune response to S. mutans proteins in patients with caries, with history of caries and without caries, in order to determine which S. mutans proteins participate in...

INTRODUCTION Dental caries pose distinct challenges when it comes to determining their microbial etymology. Streptococcus mutans play an important role in dental caries. The aim of the present study was to compare oral microbiota in infants delivered by these different routes. A study was conducted on 40 infants. Swab sample collection was done for the detection of S. mutans. Our study indicate...

Culture methods traditionally have been used to isolate and identify bacterial species in clinical specimens. Culture methods are difficult when the specimen is as bacteriologically complex as dental plaque1 and when the organism in question, such as Streptococcus mutans, is present in modest numbers. The fluorescent antibody test (FAT) has been suggested as a potentially simpler method of dete...

background and aims. streptococcus mutans is the main pathogenic agent involved in dental caries, and may be eliminated using mouthwashes. the objective of this study was to compare the effects of fluoride, chlorhexidine, and fluoride-chlorhexidine mouthwashes on salivary s. mutans count after two weeks of use and determine the prevalence of their side effects on the oral mucosa. materials and ...

conclusions the current study indicated that the immunoreactivity of secretory iga might have no direct correlation with the colonization of indigenous flora and rejection of exogenous strains in adults. the relationship of microbes, host and dental caries should be in the light of coevolved microecosystem as a whole, but not caused by one factor alone. results the results showed that naturally...

BACKGROUND Streptococcus mutans forms biofilms as a resistance mechanism against antimicrobial agents in the human oral cavity. We recently showed that human cathelicidin LL-37 exhibits inhibitory effects on biofilm formation of S. mutans through interaction with lipoteichoic acid (LTA), but without antibacterial or biofilm dispersal abilities. (-)-Epigallocatechin gallate (EGCG) is the most ab...

Biofilms formed on tooth surfaces are comprised of mixed microbiota enmeshed in an extracellular matrix. Oral biofilms are constantly exposed to environmental changes, which influence the microbial composition, matrix formation and expression of virulence. Streptococcus mutans and sucrose are key modulators associated with the evolution of virulent-cariogenic biofilms. In this study, we used a ...

AIM To evaluate the effect of fluoride varnish on Streptococcus mutans count in saliva among 12-year-old school children. MATERIALS AND METHODS A field experiment was conducted to evaluate the effects of fluoride varnish on S. mutans count in saliva among 12-year-old school children. A total of 42 school-going children attending schools in Vadodara district, Gujarat, India, were divided into ...
