Dental caries is an infectious and transmissible disease, in which many genetic, environmental and behavioral risk factors interact. The mutans streptococci (MS), mainly Streptococcus mutans and Streptococcus sobrinus are the microorganisms most strongly associated with this disease. The main virulence factors associated with MS cariogenicity include adhesion, acidogenicity and acid tolerance. ...

Aim: To compare the antimicrobial efficacy of five Medicinal plant extracts against two strains of Streptococcus mutans causing dental caries using Agar well diffusion method. Materials and methods: Five plant extracts were prepared by soxhlet extraction method using organic solvent. These extracts were tested against Streptococcus mutans MTCC 497& MTCC 890 causing dental caries by Agar well di...

background and objectives: dental caries is still remained as a major health problem. this problem has created a new interest to search for new antimicrobial agents from various sources including medicinal plants. since limited data is available so far regarding the antibacterial effect of coriandrum sativum seed and dentol drop against streptococcus mutans, this study aims to assess this activ...

Dental caries is the result of bacterial metabolic activity in dental biofilm with bacterium Streptococcus mutans, identified as primary etiological factor for and Lactobacillus plays an important role progression disease. The purpose study was to evaluate level cariogenic bacteria, S. mutans 30 children their respective mothers. Children affected had high levels relation free (60% 20% respecti...

The purpose of this study was to investigate the effect of cranberry polyphenol fraction on mutans streptococci. Hydrophobicity is an important factor in the adherence of bacteria to the tooth surface. We found that cranberry polyphenol fraction significantly decreased the hydrophobicity of Streptococcus sobrinus 6715, Streptococcus mutans MT8148R and JC2 in a dose-dependent manner (p<0.05). Bi...

Background: Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP again...

This study investigated the inhibitory effect of probiotic Enterococcus faecium WB2000 on biofilm formation by cariogenic streptococci. The ability of E. faecium WB2000 and JCM5804 and Enterococcus faecalis JCM5803 to inhibit biofilm formation by seven laboratory oral streptococcal strains and 13 clinical mutans streptococcal strains was assayed. The Enterococcal strains inhibited biofilm forma...

BACKGROUND AND AIM: In recent years, propolis has been introduced as one the most efficient agents against cariogenic bacteria. However, due to the lack of data on the propolis collected from Kandovan (Easthern Azarbaijan, Iran), this study was designed to investigate the effect of this type of propolis on Streptococcus mutans (S. mutans).METHODS: In this experimental study, the ethanolic extra...

Bakuchiol was isolated from the seeds of Psoralea corylifolia, a tree native to China with various uses in traditional medicine, followed by extraction with ether and column chromatography combined with silica gel and octyldecyl silane. In this study, the antimicrobial activities of bakuchiol against some oral microorganisms were evaluated in vitro. The cell growth of Streptococcus mutans was i...

STATEMENT OF THE PROBLEM Dental caries is the most common disease of childhood. Using probiotics has recently been introduced to reduce the incidence of dental caries.It consists of live microbial food supplements that beneficially affect the host, and hence are considered an alternative way to eradicate the infections. PURPOSE The aim of this study is to evaluate the effect of consumption of...
