UNLABELLED Streptococcus mutans is the main etiological agent for dental caries. Recently, photodynamic therapy (PDT) has been introduced as a new modality in bacterial decontamination. OBJECTIVE This in vitro study was carried out to evaluate the susceptibility of Streptococcus mutans to antibacterial PDT using two different photosensitizers and light sources. MATERIAL AND METHODS Standard...

Chromosomal DNA from Streptococcus mutans strain UAB90 (serotype c) was cloned into Escherichia coli K-12. The clone bank was screened for any sucrose-hydrolyzing activity by selection for growth on raffinose in the presence of isopropyl-beta-D-thiogalactoside. A clone expressing an S. mutans glucosyltransferase was identified. The S. mutans DNA encoding this enzyme is a 1.73-kilobase fragment ...

BACKGROUND New approaches for chemomechanical caries removal require effective materials with antibacterial properties for removal of infected dentin. Apacaries gel is a newly developed material comprised polyphenol from mangosteen extracts and papain mixed in gel preparation. AIM This study evaluated the antibacterial effects of Apacaries gel on Streptococcus mutans in vitro. MATERIALS AND...

This study developed an antibacterial oral gel to inhibit Streptococcus mutans, a bacterium that causes tooth decay. The was formulated using methanol extract of Piper betel leaves, hydroxypropyl methylcellulose and glycerin at different concentrations. evaluated for pH, viscosity activity against S. mutans standard methods. showed potent activity, supporting its use in the formulation. In sili...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...

We report the draft genome sequence of Streptococcus mutans strain HM isolated from a 4-year-old girl with infective endocarditis. The genomics information will provide information on the genetic diversity and virulence potential of S. mutans strain HM.

background: dental caries is one of the most prevalent infectious diseases affecting humans of all ages. streptococcus mutans has an important role in the development of dental caries by acid production. the purpose of this study was to evaluate the antibacterial and biofi lm disinfective effects of the oak tree quercus infectoria galls against s. mutans. materials and methods: the bacterial st...

OBJECTIVES This study was attempted to incorporate an antibacterial monomer, methacryloxylethyl cetyl dimethyl ammonium chloride (DMAE-CB), into a commercial dental adhesive and to evaluate the antibacterial activity of the DMAE-CB-incorporated adhesive after being cured against Streptococcus mutans. METHODS DMAE-CB was incorporated at 3% (w/v) into a clinically used dental adhesive, Single B...

AIM The purpose of this study is to evaluate the effect of full mouth rehabilitation on the amount of S. mutans in children with Early Childhood Caries. MATERIALS AND METHODS Thirty-nine children between 2 and 5 years old treated under general anaesthesia participated in this study. Prior to treatment two baselines samples were collected, one of dental plaque and one of saliva. In addition, s...

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 ...
