UNLABELLED The aim of this study was to evaluate the influence of chlorhexidine gluconate, sodium fluoride and sodium iodine on mutans streptococci counts in saliva of irradiated patients. MATERIAL AND METHODS Forty-five patients were separated into three experimental groups and received chlorhexidine (0.12%), sodium fluoride (0.5%) or sodium iodine (2%), which were used daily during radiothe...

Background: ECC is one of the most common chronic infectious diseases preschool-aged children (3).Mutans Streptococci (MS) cheif microorganism that causes Saliva a significant factor in thedevelopment teeth decay. have many innate defense molecules take part protection oforal tissues by either direct antimicrobial effect or interference with microbial colonization. These moleculesinclude peptid...

BACKGROUND To evaluate the effects of the lactic acid bacterium Lactobacillus salivarius on caries risk factors. METHODS The study was performed in 64 healthy volunteers to evaluate the effects of L. salivarius-containing tablets on caries risk factors. The participants were divided randomly into four groups, and took tablets containing L. salivarius WB21, L. salivarius TI 2711, Ovalgen® DC (...

BACKGROUND/PURPOSE Although habitual consumption of xylitol reduces cariogenic streptococci levels, its effect on beneficial oral streptococci is less clear. The main aim of the study is to investigate the effect of short-term xylitol consumption on the oral beneficial streptococci level of saliva, Streptococcus sanguinis and S. mitis. MATERIAL AND METHODS Twenty four volunteers with a median...

Sucrose labeled in the fructosyl ((3)H) and glucosyl ((14)C) moieties was used to quantitate extracellular polysaccharide production and degradation by cariogenic and noncariogenic oral streptococci. All of the strains produced glucan and fructan. Streptococcus salivarius produced primarily fructan, whereas S. mutans and S. sanguis produced more glucan than fructan. The cariogenic streptococci ...

Active immunization with Streptococcus mutans glucan binding protein B (GBP-B) has been shown to induce protection against experimental dental caries. This protection presumably results from continuous secretion of salivary antibody to GBP-B, which inhibits accumulation of S. mutans within the oral biofilm. The purpose of this study was to explore the influence of short-term (9- or 24-day) pass...

Dental caries is the most common chronic disease which involve the civilized humankind and is designated as the “disease of the civilization”. Oral Streptococci such as S. sanguis, S. salivarius and S. mutans have a very important role to play in the process of plaque formation. In order to inhibit and control caries process, the growth of such Streptococci must be reined. The purpose of this s...

Quantitative culture techniques that estimate the magnitude of oral reservoirs of bacteria or fungi have utilized methods that enumerate colony forming units (CFU) per milliliter of saliva or rinse solution. 1-~ This technique requires the subject population’s cooperation in rinsing and/or expectorating, so it generally is not successful with children younger than 5 years old. A technique for y...

Within the repertoire of antibiotics available to a prescribing clinician, the majority affect a broad range of microorganisms, including the normal flora. The ecological disruption resulting from antibiotic treatment frequently results in secondary infections or other negative clinical consequences. To address this problem, our laboratory has recently developed a new class of pathogen-selectiv...

This study was conducted to identify the factors involved in the antibacterial activity of glass ionomer cement (GIC) on mutans streptococci. The antibacterial effect of GIC was estimated using agar plates infected with strains of S. mutans and S. sobrinus. The effect of pH and fluoride release of GIC on mutans streptococci was studied under acid and neutral pH. Strains of S. sobrinus were more...
