Introduction: Early childhood caries (ECC) is one of the most common problems in children worldwide which is seen in 3-45% preschool children population. Bacterial factor is one of the main four components (time, microorganism, diet, host) to create caries. Streptococcus mutans is one of the most important cariogenic microorganisms. The objective of this study is evaluating Streptococcus mutans...
OBJECTIVE Dental caries is a common infectious disease. Streptococcus mutans is the pre-valent decay microorganism. The anti Streptococcus mutans activity of non fermented and semi-fermented tea has been shown. The aim of this study was to determine the anti Streptococcus mutans activity of Iranian green and black tea (non fermented and fermented type). MATERIALS AND METHODS The study was exp...
OBJECTIVE To evaluate the antimicrobial properties of several mouthwash concentrations on oral Streptococcus mutans and Escherichia coli. METHODS The study was conducted at Shiraz Medicine School in 2011. Serial dilutions of Chlorohexidin, Oral B and Persica and Irsha (2,4,8,16,64,128) were prepared in Muller-Hinton media. Minimum inhibitory concentration was visually determined and defined a...

The incorporation of polymerizable cationic monomers has been attempted to generate dental resinous materials with antibacterial activity. This study tested the hypothesis that a dental adhesive containing a cationic monomer, methacryloxylethyl cetyl dimethyl ammonium chloride (DMAE-CB), would influence biofilm formation and gtf gene expression of Streptococcus mutans. The effect of the photo-p...
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 ...
Background and Aims: Dental caries is an infectious disease transmitted by multiple factors in the mouth and one of the most common chronic diseases in the world that requires a lot of treatment expenses. The aim of this study was to evaluate the effect of fluoride 0.2% and Fuchs mouthwash (a combination of xylitol and fluoride 920 ppm) against two bacterial growths (Streptococcus mutans and ...
Pyruvate kinase of Streptococcus mutans JC 2 had an absolute and specific requirement for glucose-6-phosphate. Inorganic phosphate was a strong inhibitor. The enzyme required K+ or NH4+ and Mg2+ or Mn2+. S. mutans FIL and E 49, Streptococcus bovis ATCC 9809, and Streptococcus salivarius ATCC 13419 had also glucose-6-phosphate-dependent pyruvate kinases, whereas Streptococcus sanguis NCTC 10904 ...
Introduction: Tooth decay is one of the most essential and costly diseases globally, which is caused by the formation of biofilms by various bacteria. This study aimed to investigate the synergistic antibacterial effect of Rosmarinus officinalis and Eugenia caryophyllataon inhibiting the growth and biofilm obtained of Streptococcus mutans and Streptococcus sanguinis bacteria. Methods: Rosmarin...
dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. this study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such diseases.saponins were extracted from bauhinia purpurea, madhuca longifolia, celastrus paniculatus and sem...
