Objectives: The aim of this study is to investigate the effectiveness of dentifrice containing xylitol on the growth of salivary mutans streptococci. The amount of salivary mutans streptococci which was taken before and after tooth brushing from the groups using dentifrice containing xylitol and non-xylitol dentifrice are compared. The study was carried out to investigate the effect of dentifri...

The authors declare no conflict of interest. The caries-controlling or preventing effect of xylitol is more than just excluding fermentable sugars from the diet. This review aims to discuss the specific effects of xylitol which could have contributed to the results of the caries trials. Xylitol promotes mineralization by increasing the flow of saliva, an effect it has in common with all sweeten...

Dental caries is an infectious and transmissible disease. The mutans streptococci and some Lactobacillus species are the two groups of infectious agents most strongly associated with dental caries. Earlier studies demonstrated that infants acquire mutans streptococci from their mothers and only after the eruption of primary teeth. More recent studies indicate that mutans streptococci can coloni...

Dental plaque was obtained from one or two sound root surfaces of subjects with different degrees of root-surface caries experience. From subjects with root-surface caries, plaque samples were also obtained from either one incipient or one more advanced lesion. Proportions of the total flora were determined for total streptococci and different streptococcal species, total and different Actinomy...

The aim of this study was to analyze the distribution and phenotypic properties of the indigenous streptococci in chimpanzee (Pan troglodytes) oral cavities. Eleven chimpanzees (aged from 9 to 44 years, mean ± SD, 26.9 ± 12.6 years) in the Primate Research Institute of Kyoto University were enrolled in this research and brushing bacterial samples collected from them. Streptococci were isolated ...

PURPOSE Streptococcus mutans has been implicated as the major causative agent of dental caries. Although restorative treatment for caries is thought to temporarily eliminate the carious challenge, there are few reports of alterations in salivary mutans streptococci (MS) numbers and no reports of changes in salivary IgA antibody to S. mutans following restorative treatment. METHODS This study ...

background and aims. espar is a dairy product of probiotic nature that contains useful bacteria and high calcium con-tent. the aim of this study was to analyze effects of daily consumption of espar on the number of salivary mutans strepto-cocci and the level of calcium content in a population of 15 to 17 year-old female students. materials and methods. a double-blind randomized crossover study ...

We evaluated the effects of special oral care using a toothbrush with combined irrigation and suctioning functions, along with povidone-iodine to treat oral bacteria and mucositis, in esophageal cancer patients undergoing chemoradiotherapy. In the special care group, oral hygiene was performed 3 days a week after dinner. Bacteria in saliva and plague samples were measured at various sampling po...

AIM To evaluate the association between dental health status and levels of cariogenic bacteria in teenagers and the influence of behaviours and socio-demographic background on levels of bacteria. MATERIALS AND METHODS Study design: A cross-sectional population-based sample of 13-year-old adolescents (112 females and 78 males, total 190) was examined. The number of decayed, missing and filled ...

The purpose of the present study was to investigate whether the use of a chitosan mouthrinse could be efficacious in reducing plaque and saliva mutans streptococci level. A randomized crossover clinical trial was performed to evaluate the effect of a rinse with 0.5% chitosan for 14 days on plaque formation and mutans streptococci counts in saliva. Twenty-four subjects were randomly assigned eit...
