Dental caries is one of the most common prevailing disease in humans and a significant public health problem worldwide. Mutans streptococci are a group of oral bacteria, among this group Streptococcus mutans and Streptococcus sobrinus are frequently associated with dental caries. The aim of the present study was (i) To investigate the reliability of morphological, biochemical and multiplex PCR ...

The aim of this study was to assess the antimicrobial activity of the miswak chewing stick (Salvadora persica) in vivo, especially on streptococcus mutans and lactobacilli. The study was conducted clinically using patients' saliva and measuring the effect of miswak (chewing stick), miswak extract, toothbrush, and normal saline on mutans and lactobacilli. Forty male subjects aged 20-45 years wer...

Article history: Received on: 11/05/2015 Revised on: 29/05/2015 Accepted on: 09/06/2015 Available online: 27/06/2015 Dental caries is one of the oldest disease in the world and its causative agent is mutans streptococci (MS). Among MS, Streptococcus mutans and Streptococcus sobrinus are implicated in caries active subjects. The objective of this study was to identify and determine the antibiogr...

statement of problem: streptococcus viridans is one of the most important micro-organisms in the establishment of infections leading to dental caries and heart valve damages. therefore the diagnosis and prevention of these infections is critical in health care. purpose: the aim of this in-vivo study was to determine the prevalence of viridans streptococci in abscesses occurring in the maxillofa...

BACKGROUND One of the causative factors in development of dental caries is microorganisms. Two species of Mutans streptococci including Streptococcus mutans and Streptococcus sobrinus are associated with dental caries in human beings. The aim of this study was to investigate the frequency of S. mutans and S. sobrinus in saliva of children with different caries activity and ability to form biofi...

The survival of pooled plaque bacteria and a mixed suspension of Streptococcus mutans, Streptococcus sanguis, Streptococcus mitis, and Streptococcus saliuarius were tested in three transport media. A new, non-nutritive, reduced transport fluid, RTF, was compared with VMG II and SBL, two recognized transport media. Specimens were stored in several vials of each medium and held at either 10°C or ...

A PCR assay that allows identification of clinically relevant viridans group streptococci (Streptococcus gordonii, S. mitis, S. mutans, S. oralis, S. salivarius, and S. sanguis) to the species level and identification of milleri group streptococci (S. anginosus, S. constellatus, and S. intermedius) to the group level was developed. This assay was based on specific amplification of internal frag...

OBJECTIVE The probiotic strain Lactobacillus rhamnosus GG (LGG) is shown to hamper the presence of mutans streptococci in saliva and may have positive effects on oral health. We investigated the effects of LGG on the cariogenic potential and microbial composition of saliva-derived microcosms. DESIGN Single and dual species biofilms of LGG and Streptococcus mutans, and saliva-derived microcosm...
