2. Cariogenic Pathogens Flashcards
1
Q
What pH must oral environment be less than to begin demineralisation ?
A
<5.5
2
Q
What is the ‘odontopathogen’ ?
A
Strep. mutans.
3
Q
What virulence factors does strep. mutans have to make it a successful odontopathogen ?
A
Glycolytic systems - fermentation of carbohydrates.
Sucrose metabolism.
Attachment mechanisms - antigens and adhesions.
Greater acidogenicitiy - survives better in low pH.
4
Q
Explain conversion of fermentable carbohydrates to acid.
A
ATP to ADP conversion causing release of hydrogen ions and makes resilient to high pH.
