200

All methods of toothbrushing should include ______ brush postitions.

overlapping

300

List 3 factors for TB selection.

1. Toothbrush must have seal of approval (CDA, ADA) 

2. Patient (dexterity, age, etc.)

3. Gingiva (health vs. disease and atomic configurations) 

4.  Teeth (crowding, open contacts) 

5. Compliance (pt preference, motivation, willingness, ability) 

6. Method selected 

400

______ is the wearing away of gingiva and tooth structure due to repetitive mechanical habit. 

Dental abrasion 

500

Differentiate between Stilman's cleft and McCall's festoon 

Stilman's cleft = apostrophe shaped indentation of the GM (usually on the facial surface).

McCall's Festoon = life preserver shaped inflammation of the GM.
