Caries Flashcards
What kind of diet are streptococcus mutans linked to?
High sugar diet
What causes caries to develop?
Erosion caused by weak acids
Bacterial biofilm with fermentable carbohydrates create acid production which leads to the demineralisation of teeth
What are the stages of caries progression?
Adhesion
Survival & growth
Biofilm formation
Complex plaque
Acid
Caries
What are some features of streptococcus mutans?
Glycolytic systems
Sucrose metabolism
Attachment mechanisms
Greater acidogenicity
Ecological competitiveness at low pH
Genomic characteristics
What are some factors related to cargiogenicity of streptoccocus mutans?
Produces water-soluble and insoluble extracellular polysaccharides from sucrose which help in the colonisation of tooth surfaces by consolidating microbial attachment
Ability to initiate and maintain microbial growth and to continue acid production in site with low pH
Rapid metabolism of sugars to lactic acid
Can attain the critical pH for enamel demineralisation more rapidly than other common plaque bacteria
What bacteria causes caries?
Streptoccocus mutans
Actinomyces
Bifidobacterium
Lactobacillus and veillonella
