Competition and coexistence between Streptococcus mutans and Streptococcus sanguinis in the dental biofilm.
The human mucosal surface is colonized by the indigenous microflora, which normally maintains an ecological balance among different species. Certain environmental or biological factors, however, may trigger disruption of this balance, leading to microbial diseases. In this study, we used two oral bacterial species, Streptococcus mutans and Streptococcus sanguinis (formerly S. sanguis), as a mod...
متن کاملEffect 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...
متن کاملIn Vitro Effect of Hydroalcoholic Extract of Aloe Vera and 0.2% Chlorhexidine Mouthwash on Streptococcus Sanguinis, Streptococcus Salivarius and Streptococcus Mutans
Objectives: This study aimed to assess the antimicrobial effects of aloe vera hydroalcoholic extract and 0.2% chlorhexidine (CHX) mouthwash on Streptococcus sanguinis (S. sanguinis), Streptococcus salivarius (S. salivarius) and Streptococcus mutans (S. mutans) in vitro. Materials and Methods: Four concentrations (25%, 50%, 75% and 100%) of hydroalcoholic extract of aloe vera were prepared. S. ...
متن کاملStreptococcal antagonism in oral biofilms: Streptococcus sanguinis and Streptococcus gordonii interference with Streptococcus mutans.
Biofilms are polymicrobial, with diverse bacterial species competing for limited space and nutrients. Under healthy conditions, the different species in biofilms maintain an ecological balance. This balance can be disturbed by environmental factors and interspecies interactions. These perturbations can enable dominant growth of certain species, leading to disease. To model clinically relevant i...
متن کاملStreptococcus mutans and Streptococcus sobrinus biofilm formation and metabolic activity on dental materials.
OBJECTIVES To examine potential correlations between streptococcal biofilm formation and lactate production in streptococcal biofilms formed on the surface of dental materials with different surface characteristics. MATERIALS AND METHODS Samples of a glass-ionomer cement (Ketac Molar) and a ceramic (Empress 2) were incubated with whole saliva and suspensions of Streptococcus mutans ATCC 25175...
