CORONAL POLISH AND SEALANTS
EXAM QUESTIONS AND ANSWER
what is the purpose of dental sealants? - Correct Answers -to prevent dental caries in
the pit and fissures
should sealants be the only preventive measure used? - Correct Answers -no, the
patient still needs properly brush and floss
what are the types of polymerization? - Correct Answers --self cure
-light cure
why is clear sealant material less desirable? - Correct Answers -because they are
harder to see during application and check ups
when tooth enamel begins to demineralize, what correctly measure can be taken to
stimulate remineralization? - Correct Answers -use a daily rinse containing fluoride
when enamel is remineralized with fluoride ___? - Correct Answers -the resultant
reminerlized crystal is more resistant to acids
fluorosis is always considered to be __? - Correct Answers -a sign that the person has
ingested more than the optimum amount of fluoride
when tooth enamel begins to demineralize, what correctly measure can be taken to
stimulate remineralization? - Correct Answers -use a daily rinse containing fluoride
when enamel is remineralized with fluoride ___? - Correct Answers -the resultant
reminerlized crystal is more resistant to acids
fluorosis is always considered to be __? - Correct Answers -a sign that the person has
ingested more than the optimum amount of fluoride
is there a difference in retention rates between filled and unfilled sealants? - Correct
Answers --unfilled- if too high can wear off in a few days or weeks
-filled- much more wear resistant
what is the purpose for putting fluoride in dental sealant material? - Correct Answers -
may create a fluoride - rich layer at the base of the sealed grove, helping to remineralize
incipient enamel caries
, what is the range of shelf life for sealant material? - Correct Answers -they each vary
but most are room temp. from 18-36 months.
what are the two patient safety precautions to keep in mind when using sealants. -
Correct Answers --moisture control (so that the phosphoric acid does not touch the soft
tissues)
-protective eyewear for them so that no debris gets in their eyes
what determines the effectiveness of sealants? - Correct Answers -moisture
what is coronal polish? - Correct Answers -a technique used to remove plaque and
stains from the coronal surfaces of teeth
what is the difference between a coronal polish and an oral prophylaxis ? - Correct
Answers -coronal polish- removes stains and plaque
prophylaxis- is called a prophy or cleaning and is the complete removal of calculus,
debris, stain, and plaque from the teeth
what is the purpose of selective polishing? - Correct Answers -only to focus on the teeth
or surfaces with stains
what is an exrinsinic stain? - Correct Answers -stains that appear on the exterior part of
the teeth and can be removed
what is an intrinsic stain ? - Correct Answers -stains that are incorporated into the tooth
structure , usually during the tooth's development
what is the most common technique for stain removal ? - Correct Answers -rubber
polishing cup
which type of grasp is used to hold the handpiece ? - Correct Answers -pen grasp with
handle resting in the u-shaped area of your hand
what is the purpose of a fulcrum? - Correct Answers -stability
what precaution should be taken when esthetic type restorations are polished? - Correct
Answers -regular prophy paste is not recommended. mirco - fine sapphire or diamond
paste or aluminum oxide paste that are low abrasive and should be used for 30 secs. w/
rubber cup
in which direction should a polishing cup stroke move? - Correct Answers -begin from
distal surface of the most posterior tooth and work toward the anterior
what damage can happen from the use of a prophy cup at highspeed? - Correct
Answers -pulpal damage
