The present study examined the hypothesis that women with eating disorders associated with a history of chronic vomiting can be characterized by a salivary flora with high levels of aciduric organisms, such as, mutans streptococci, lactobacilli and yeast. Three groups of female subjects were studied: vomiting bulimics (G1; n = 14), and comparison groups selected for high Streptococcus mutans (G...

Background and aim: The present study examined the in vitro effect of pure glycoside Stevioside hydrate on pH, growth and biofilm formation of Streptococcus mutans. Method: S. mutans were supplemented with different concentrations of Stevioside hydrate. Bacterial growth, metabolism and effect on biofilm formation were examined. Results: The presence of Stevioside hydrate had no significant effe...

OBJECTIVE To verify, by means of a systematic review, whether the design of brackets (conventional or self-ligating) influences adhesion and formation of Streptococcus mutans colonies. METHODS SEARCH STRATEGY four databases (Cochrane Central Register of Controlled Trials, Ovid ALL EMB Reviews, PubMed and BIREME) were selected to search for relevant articles covering the period from January...

The aim of this study is to compare the effect of herbal based and fluoride based tooth pastes on Streptococcus mutans. The effect of the toothpastes are compared and hence an idea on how to prevent, control and treat the dental caries is formulated. Streptococcus mutans is a bacterium commonly found in the human oral cavity and is a significant contributor to tooth decay. The bacterial count i...

Introduction: In India, mango, neem and babool chewing twigs are considered a common way of cleaning teeth. Dental caries is steadily increasing in the underdeveloped and developing countries. These twigs possess medicinal properties. The present study was conducted to evaluate the antimicrobial efficacy of these chewing sticks on the caries causing microorganism, Streptococcus mutans. Aim: An ...

Caries is a multifactorial disease, and studies aiming to unravel the factors modulating its etiology must consider all known predisposing factors. One major factor is bacterial colonization, and Streptococcus mutans is the main microorganism associated with the initiation of the disease. In our studies, we have access to DNA samples extracted from human saliva and blood. In this report, we tes...

UNLABELLED Glucosyltransferase B is an enzyme produced by Streptococcus mutans, which catalyzes synthesis from sucrose of insoluble glucans that provide support to the biofilm. It is one of the main virulence factors in the generation of dental caries. However, its role is unclear in caries-free individuals who carry the bacteria. The aim of this study was to determine the production of glucosy...

Background Many plants or herbs exhibit potent antimicrobial activity against various microorganisms. They have no side effects and presumably act against and modulate the factors that are crucial for microbial survival or their activity. Streptococcus mutans is a pioneer bacteria implicated in dental caries. This study aims to evaluate the antimicrobial activity of garlic bulbs, pudina leaves,...

Although Streptococcus intermedius and Streptococcus mutans are regarded as members of the commensal microflora of the body, S. intermedius is often associated with deep-seated purulent infections, whereas S. mutans is frequently associated with dental caries. In this study, we investigated the roles of the S. mutans and S. intermedius antigen I/II proteins in adhesion and modulation of cell su...
