answers
1-2 hours Correct Ans- how long does it take for biofilm to collect on
the pellicle after a coronal polish?
1.) potassium alginate (seaweed)
2.) calcium sulfate (forms gel)
3.) trisodium phosphate (slows reaction)
4.) zinc oxide
5.) potassium titanium fluoride Correct Ans- list ingredients of alginate
(5 important)
1.) record the alignment of the teeth
2.) relate the mx and mn casts correctly
3.) placed between the casts during trimming and storage Correct Ans-
what is the purpose of taking a bite registration? (3)
1.) removes food debris
2.) helps prevent air bubbles
3.) cuts the viscosity of saliva
4.) helps prevent gagging on the maxillary impression Correct Ans- why
is mouthwash used in an alginate impression? (4)
, 10 times harder Correct Ans- abrasives used in prophy polishing pastes
are how many times stronger than tooth structure when they are applied?
20 psi Correct Ans- what handpiece speed is sufficient to remove stain
in a mechanical polish?
3-5 seconds Correct Ans- what is the maximum amount of time that a
tooth should be polished to reduce tooth abrasion?
aluminum oxide Correct Ans- what type of polishing agent is
recommended for use to polish hybrid composite and resin restorations?
Black line stain Correct Ans- Usually teeth are clean, iron compounds in
saliva, common in females
border molding Correct Ans- muscle trimming on an edentulous patient
Brown stain Correct Ans- red-brown stain caused chlorhexidine
emery Correct Ans- not used directly on enamel, polishes acrylics and
composites
Endogenous stains Correct Ans- Stains developed within the structure of
the tooth, acquired during tooth development, CANNOT be removed by
polishing ex; tetracycline
