SEALANT STATE EXAM QUESTIONS
AND ANSWERS
Child classified at moderate risk for caries - Answer- frequent sugar exposure, w/
compromised oral hygiene
Adults w/ high risk demonstrates following criteria - Answer- 3 or a more caries in
past 3 years
Factors contributing to the formation of caries - Answer- Fissures less than .1mm
wide & enamel at base of fissure thinner than other areas of the tooth
Fissure described as - Answer- Imperfect joining of enamel & linear fault
A pit is described as - Answer- Small fault resulting from noncoalesced joining of
enamel
Primary cause of dental caries - Answer- By products of plaque & bacteria
what best describes incipient caries - Answer- starts as decalcification & if stopped
can repair itself
Remineralization occurs when - Answer- Calcium & phosphate in saliva is absorbed
into enamel
criteria for selecting teeth for sealants - Answer- Placed on adult teeth w/ no caries,
deep retentive, narrow pits and fissures
Who can apply sealants - Answer- RDAEF, RDA completed state board course,
hygienist dentist
When 1st introduced problem most pronounced - Answer- Retention
Characteristic of etchant material - Answer- Dissolves some of interprismatic cement
between enamel rods. Applied to susceptible pits & fissures
Helpful techniques in placement of pits & fissures - Answer- Enamel conditioning w/
35-50% phosphoric acid gel before sealant resin. Teeth done 1 quadrant at a time.
Surface not appearing frosty should be re-etched
Characteristics of drying agent include - Answer- Minimizes microleakage, enhances
moisture removal from enamel, lowers surface, tension from enamel
A photopolymerizing sealant material - Answer- is light cured
Mechanism by which sealants adhere to tooth - Answer- Sealants retained by
adhesive forces. Bonding sealant to enamel through mechanical forces.
