|
What food source is a major cause of dental caries?
|
Sucrose
|
|
|
Why is S. Mutans strongly implicated in dental caries?
|
It has been found in high concentrations in caries.
In the absence of caries it is not there. It grows at a low pH value. It causes caries in animal models. |
|
|
What other types of bacteria play a role in dental caries?
|
Lactobacilli
Actinomyces S. Mutans |
|
|
What areas of the tooth are susceptible to caries?
|
Pits
Fissures Enamel Dentin Root |
|
|
What are the virulence factors of S. Mutans?
|
Glucosyltransferase because it forms Glucans which results in Plaque.
|
|
|
What role do glucans play in dental caries formation?
|
Plaque formation and adherence of new bacteria.
|
|
|
What is vertical transmission?
|
Bacteria is passed from Mother to Child.
|
|
|
What is horizontal transmission?
|
Bacteria is passed from child to child.
|
|
|
What is Xylitol?
|
It is a sugar alcohol produced by fruits and vegetables.
It is not fermented into acids. |
|
|
What roles does fluoride play in preventing caries?
|
It hardens enamel by forming flurohydroxyapitite (FAP).
Inhibits demineralization. No known bacterial resistance. (FAT ASS PEOPLE) |
|
|
What types of dietary modifications might help to decrease dental caries?
|

Milk Cheese Cranberry Juice Water Yogurt |
