dental sealants

4. cured this type of sealant material does not need to be mixed.
6. yes or no: sealants are cost-effective.
7. this sealant material is the same polymer as acrylic but is much more heavily filled.
12. this type of acid is most often used for etching.
14. a properly etched tooth surface should be the color of this material.
15. should the tooth surface be wet or dry during sealant placement?
17. this technique is used to create multiple depressions on the tooth surface to facilitate mechanical interlocking.
18. a high spot on a sealant made with this type of material will adjust itself through normal use.
19. type of polymer used for the vast majority of sealants.
21. sealants work by using this technique to prevent microorganisms and acids from reaching the tooth surface.

1. true or false: a tooth prepared to receive a sealant should be smooth.
2. when glass ionomer sealant material is used, completing this placement step thoroughly is not essential.
3. this part of a polymer is very weak.
5. as polymers, would you expect sealant materials to be hyrophilic, or hydrophobic?
8. this type of sealant material requires mixing of two materials.
9. yes or no: sealants need to be applied only once.
10. true or false: a fluoride treatment is not always provided after a sealant is placed.
11. this type of pumice is used for polishing so as not to interfere with bonding.
13. filler in a sealant increases this property of the material.
16. Ionomer type of sealant polymer that bonds chemically to the tooth and leaches fluoride.
20. material used as a filler to increase the strength of some sealant materials.
