Tooth Deposits

Acquired pellicle is:

• A thin film of bacteria that adheres to a surface

• A protein film that adheres to the tooth surface

• A soft mass of bacteria that covers the tooth surfaces as well as the hard and soft tissues of the oral cavity.

• dental plaque

Dental Biofilm is:

• A thin film of bacteria that adheres to a surface

• A protein film that adheres to the tooth surface

• A soft mass of bacteria that covers the tooth surfaces as well as the hard and soft tissues of the oral cavity.

• dental pellicle

Leaving dental biofilm alone can cause:

• Dental caries

• gingivitis

• calculus

• halitosis

Materia alba

• is also called "white material"

• is dental biofilm

• is more common in individuals with good oral hygiene

• Is food that is stuck in the dentition

Food impaction

• looks like cottage cheese

• occurs when food is forcefully wedged interproximally or into the periodontium during mastication

• causes calculus

• cannot be removed with brushing

When a patient's oral hygiene is neglected, biofilm can mineralize into calculus within:

• 6 hours

• 24-36 hours

• 10 days

• 20 days

Calculus is more likely to form:

• on the tongue

• on the buccal mucosa

• on dentition near the opening of the saliva ducts

• subgingivally near the maxillary anteriors
