Propolis has traditionally been used in curing infections and healing wounds and burns. Current researches have shown that propolis has antibacterial, antifungal and antiviral actions however, the pharmacological activity of propolis is highly variable depending on its geographic origin. There have been few studies on the effects of Iranian propolis on the oral microorganisms. In this in-vitro ...

Enzyme I and HPr, the general proteins of the phosphoenolpyruvate-sugar phosphotransferase system, play a pivotal role in the control of sugar utilization in gram-negative and gram-positive bacteria. To determine whether growth conditions could modify the rate of biosynthesis of these proteins in Streptococcus mutans, we first purified to homogeneity enzyme I and HPr from S. mutans ATCC 27352. ...

Lactobacillus paracasei SD1 is a potential probiotic strain due to its ability to survive several conditions in human dental cavities. To ascertain its safety for human use, we therefore performed a comprehensive bioinformatics analysis and characterization of the bacterial protein toxins produced by this strain. We report the complete genome of Lactobacillus paracasei SD1 and its comparison to...

Purpose: To evaluate the antimicrobial and antibiofilm activity of A. lakoocha extract against oral pathogens by an in vitro method. Methods: The dried powder of the aqueous extract of A. lakoocha was purchased from a Thai traditional drug store. Representative strains of oral pathogens (Streptococcus mutans ATCC 25175, Streptococcus sobrinus ATCC 33478, Enterococcus faecalis ATCC 19433, Lactob...

Background: One of the main dental and oral health problems that occur throughout world is caries. Cariogenic bacteria such as Streptococcus mutans Lactobacillus acidophilus are microorganisms cause Saliva plays a significant function in maintaining optimal cavity especially because its components pH, flow, buffering capacity. These three have role initiation development Gargling one activities...

AIM The aim of this study was to assess the changes over time associated with salivary indices and the presence of Streptococcus mutans and Lactobacillus in patients treated with Occlus-o-Guide. MATERIALS AND METHODS Two groups of patients were evaluated: a test group of 20 patients treated with Occlus-o-Guide and a control group of 20 patients not subjected to orthodontic treatment. Both gro...

It is common knowledge the current trend of developing and testing products accrued from natural plants. On that premise, Stryphnodendron adstringens (Mart) Coville highlighted was aim for evaluating its antibacterial effect on dental caries. A crude dried methanolic extract prepared applied 50 to 500 mg/mL determine Minimum Inhibitory Concentration (MIC) seven distinguished bacterial cultures....

background one of the most important factors in inducing the logarithmic growth of streptococcus mutans, is a diet containing fermentable carbohydrates such as sucrose. objectives: the aim of the current research was to compare the ability of ordinary and probiotic chocolate to induce or inhibit the growth of s. mutans. materials and methods lactobacillus rhamnosus, l. plantarum and l. acidophi...
