Abrasive agent used for removal of light stains on enamel Correct Ans-
Super-fine Silex
AKA Whiting
Precipitated Calcium Carbonate: frequently incorporated into toothpaste
and polishing pastes to whiten teeth Correct Ans- Chalk
Benefits of Coronal Polishing Correct Ans- Prepares teeth for sealants
Smooth tooth surfaces are easier to keep clean
New deposit formation is slowed
Patients like smoothness and clean appearance
Prepares teeth for placement of ortho appliances
Contains an abrasive, water, a humectant, a binder, flavoring agents and
color. Correct Ans- Commercial premixed abrasive preparations
Contraindications for coronal polishing Correct Ans- No stain is present
Patients at high risk for caries
Sensitive teeth
Newly erupted teeth
Difference between polishing and prophylaxis? Correct Ans-
Prophylaxis is the complete removal calculus, debris, stain, and plaque
, Factors that influence the rate of abrasion Correct Ans- Amount of
abrasive agent used
Amount of pressure applied
Rotation speed of the polishing cup
Fairly abrasive polishing agent
cleaning more heavily stained tooth surfaces Correct Ans- Silex
How is coronal polishing done? Correct Ans- Dental handpiece with a
prophy angle
Rubber cup
Abrasive agent
How should the handpiece be held while polishing? Correct Ans- In a
pen grasp, with the use of a fulcrum preferably intramural and and
maintained as close as possible to the working area.
How should the patient be positioned when working on the mandibular
arch? Correct Ans- Chin down, lower jaw parallel to the floor?
