1

Dental caries lesion best definition:

A multifactorial process of demineralization and remineralization, and are often reversible

2

Names of bacteria that cause tooth decay:

S. mutans, S. Sobrinus, and Lactobacili
Also, other non-cariogenic bacteria can become cariogenic for short periods of time under certain conditions

3

The rate of caries formation is dependent on:

Frequency of carbohydrate intake
Oral Hygiene
Saliva Quantity/Quality
Microbial status
Tooth Surface
Host defense

4

The rate of caries formation is dependent on:

Frequency of carbohydrate intake
Oral Hygiene
Saliva Quantity/Quality
Microbial status
Tooth Surface
Host defense

5

Concise definition of Caries:

A multifactorial process of demineralization and remineralization, and are often reversible

6

What is the timeline for the development of dental biofilms?

1. Pellicle formation (minutes to hours)
2. Attachment of a single bacterial cell (0-24 hours)
3. Growth of attached bacteria leading to the formation of distinct micro-colonies (4-24 hours)
4. Microbial succession (and coadhesion) leading to increased species diversity & continued growth of micro-colonies.
5. Climax community/mature biofilm (> 1 week)

7

What is the specific plaque hypothesis?

It agrees plaque is a problem BUT it is not the plaque itself but the specific concentration of cariogenic bacteria.

8

How do you treat in the specific plaque hypothesis?

Plaque removal, dietary review and modification, bacterial testing, and antimicrobials
