Prevalence of transformable Streptococcus mutans in human dental plaque

Role of Streptococcus mutans in human dental decay.

Identification of Streptococcus mutans serotypes in dental plaque by fluorescent antibody techniques.

The presence of Streptococcus mutuns in dental plaque may be related to human dental caries. The cultural identification of this organism in plaque is not likely to be used routinely in a clinical or epidemiological situation. In an effort to develop a simpler diagnostic means of identifying Strep. mutans in plaque, antisera were prepared for the 5 known serotypes of Strep. mutuns. These immune...

spaP gene of Streptococcus mutans in dental plaque and its relationship with early childhood caries.

AIM Streptococcus mutans and Streptococcus sobrinus are the main pathogens associated with the development of dental caries in humans. Recently, the real-time polymerase chain reaction (qPCR-TR) has been used for fast and exact quantification of these bacteria species. This molecular biology method has made the detection of these bacteria in saliva and dental plaque possible; additionally, i...

Effect of fluoride on growth and acid production by Streptococcus mutans in dental plaque.

The aim of this study was to measure the effect of fluoride on the production of organic acids by Streptococcus mutans in dental plaque. The effect was studied in a simplified model of dental plaque with gnotobiotic rats monoinfected with S. mutans Ny341. Adaptation of S. mutans to fluoride was induced by feeding one group of the rats on fluoride-containing diet and drinking water. No differenc...

Effect of Isolated Specific Lytic Phage against Growth and Biofilm Inhibition of Streptococcus mutans and Streptococcus sanguinis Isolated from Decayed Dental Plaque

Background and purpose: Despite advances in oral health and dental industry, tooth decay remains one of the most common oral diseases. One of the new methods to combat dental plaque, which is the main cause of caries, is using specific lytic bacteriophage. This study aimed to investigate the effect of isolated specific lytic phage against growth and biofilm inhibition of Streptococcus mutans an...
