MN Licensure Exam (olivia raeE)
Describe the motion/pressure when performing a mechanical polish. - ANS -A quick light
to moderate pressure should be used. on slow speed pushing gently and overlapped.
What part of the rubber cup does the polishing? - ANS -THE OUTER EDGE DOES THE
POLISHING
If a line of stain or deposits appear along the gingival margin after polishing, the problem
was? - ANS -the prophy cup was not flexed or adapted to the tooth.
The stroke used to polish a tooth is from the ---- third to the --- edge. - ANS -gingival third
to the incisal edge
A mechanical polish removes what deposits and stains? - ANS -All soft deposits and
extrinsic exogenous stains
List the objectives of a mechanical polish? - ANS -Creates smooth surfaces easier for
patient cleaning, all soft deposits extrinsic stains removed, contributes to pt. motivation.
What does excessive speed during a mechanical polish cause? - ANS -Abrasion and
tramuatic frictional heat
List other factors that increase the rate of abrasion? - ANS -Dry Coarse Polishing Agent,
irregular particles in polish, larger particles, Grit, Number of particles, Amount of
pressure and speed
Why is unwaxed floss preferred? - ANS -May spread out more
How would you remove heavy stains? - ANS -Scaling (and/or) root planing (Cannot be
done by LDA)
RDA would use a higher grit polishing paste
Define characteristics of tissue abrasion from an incorrect placement of a rubber cup. -
ANS -Red tissue and hurting
Describe the movement of the hand to adapt the cup to the tooth when polishing. - ANS
-Use short overlapping, intermittent motions or stroking, lifting, wiping motion with wrist
rotation
, Give characteristics or a description of how you would explain a mechanical polish to a
new patient that is 3-4 years old. - ANS -Show, Tell in a way they will understand, let
them Feel like prophy cup on finger, and use imagination
What is used interproximally with an abrasive to remove stains? - ANS -Dental Floss,
Tape
To polish place abrasive on contact areas between teeth and work floss/tape into
contacts
Which stain is being described?
Occurs in patient with poor oral hygiene where plaque collects - ANS -Brown and Yellow
Stain
Which stain is being described?
Located on the cervical 1/3 of the maxillary anterior labials - ANS -Green Stain ( Light to
Yellowish)
Which stain is being described?
Follows contour of gingival 1 mm of maxillary anterior labials - ANS -Green Stain (Light
to yellowish)
Which stain is being described?
Gummy and is found on lingual of anterior teeth - ANS -Tobacco Stain
Which stain is being described?
Intrinsic, grayish brown and caused by an antibiotic. - ANS -Tetracycline
When is wax floss used? - ANS -When stronger floss is needed
Contact prior to RD (Rubber Dam) placement
For flossing and polishing interproximally
What abrasive removes tenacious heavy stain? (tobacco) - ANS -Silex
What is pumice used for? - ANS -Removes persistent stains (not used on solid/resin) no
fluoride is in it
What is zirconium silicate used for? - ANS -Cleans/polishes enamel, used on root
surfaces, crowns
What is Whiting used for? - ANS -Polishes dentures (precipated Chalc)
What is tin oxide used for? - ANS -Polishing teeth and metallic restorations (fine white
powder)
