چکیده
Streptococcus mutans is a Gram-positive, non-motile, non-spore forming, catalasenegative, facultative anaerobic cocci bacterium commonly found in the human oral cavity, is a significant contributor to tooth decay (David et al., 2011). The mutans streptococci comprise a group of seven species, of which Streptococcus mutans and Streptococcus sobrinus are the predominant species isolated from human saliva and ISSN: 2319-7706 Volume 3 Number 10 (2014) pp. 1-10 http://www.ijcmas.com

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...
متن کاملFrequency, biofilm formation and acid susceptibility of streptococcus mutans and streptococcus sobrinus in saliva of preschool children with different levels of caries activity
BACKGROUND One of the causative factors in development of dental caries is microorganisms. Two species of Mutans streptococci including Streptococcus mutans and Streptococcus sobrinus are associated with dental caries in human beings. The aim of this study was to investigate the frequency of S. mutans and S. sobrinus in saliva of children with different caries activity and ability to form biofi...
متن کاملAntibodies to indigenous and laboratory strains of Streptococcus mutans in saliva from children with dental caries and from caries-free children.
Whole, unstimulated saliva and dental plaque were collected from 63 children ages 6-13 years, 29 with dental caries and 34 without. If a child was infected with Streptococcus mutans, it was isolated from dental plaque and characterized. Saliva was tested for IgM, IgG, and IgA that would bind indigenous S. mutans, if present, and for antibodies that would bind 6 laboratory strains of S. mutans, ...
