Yellowish brown or gray brown (translucent or opalescent)

5

What happens with dentures during a polishing procedure

Kept in a wet paper towel to keep from distorting

6

Polishing procedure steps

Lifting wiping motion, flange prophet cup into sulcus, dry working area

Endogenous

Within tooth from developmental and systemic disturbances, excessive fluoride during formation, tetracycline

8

Exogenous

Outside caused by environmental agents

9

What is commonly used for cleaning and polishing of tooth surfaces

Abrasive zirconium silicate

10

Another name for dental fluorosis

Endogenous developmental stain

11

Sequence for coronal polishing

Disclose, polish, floss, disclose

12

What negative affect can course abrasive have

13

Is abrasion greater with dentin or enamel

Dentin

14

Silex

Fairly abrasive used for heavy stains

15

Super fine silex

Doesn't abrade used for polish

18

Chalk

Precipitated calcium carbonate combine with toothpaste and polishing paste

19

Commercial premixed

Variety of grits contain abrasive, water, humectant, binder

20

What is true of polishing and fluoride

Does not improve uptake of fluoride polish not necessary prior to uptake of fluoride

Buccal surface of maxillary molars/lingual surface of lower anterior incisors poor hygiene

22

What stains are most commonly found on children

Green and nasmyth membrane

23

What damage can be caused from using prophy at high speed
