1

Resin material applied to the pits and fissures of teeth

Dental sealants

2

The process of changing a simple chemical into another substance that contains the same elements

Polymerization

3

A technique used to open fissures before sealant is placed

Microabrasion

4

A sealant material that does not contain filler particles

Unfilled resin

5

A salt or ester or acrylic acid

Acrylate

6

Sealant firmly adheres to the tooth surface because of...

Sealant retention

7

Why is clear sealant material less desirable

More difficult to evaluate

8

What is the difference between filled and unfilled sealants with regard to retention rates

No difference

9

What is the range of shelf life of sealant materials

18-36 months

10

What are sealants and what do they provide

"Plastic coverings" provides mechanical barrier against cariogenic bacteria

11

Caries risk factors

Accumulation of plaque, cariogenic diet, history of caries, low fluoride intake, pit and fissure anatomy

12

Do teeth need to be fully erupted before placing sealants

No

13

Can you do sealants if there are caries present interproximally

No

14

What does frank mean

Suspicious

15

What type of sealant material release fluoride and is moisture tolerant

Glass ionomer

16

What are glass ionomer sealants a good choice for

Partially erupted, difficult to isolate transitional sealant

17

What do resin based sealants provide

Higher bond strengths and longer retention

18

Self etch technique

Clean teeth, no cleaning medium containing fluoride or oils (affects adhesion), rinse, isolate, dry, activate L-pop

19

How to apply L-Pop

Churning or spinning motion to applicator for 5 seconds to mix adhesive

20

What color should the applicator on the L-Pop be when properly activated

Light yellow tint. If not unfold and reactivate. Clear indicates improper activation

21

How long do you scrub adhesive onto surface to be sealed

15 seconds

22

How far in advance can the l-pop be activated

10 minutes

23

What is the highest risk period for decay after a tooth erupts

Within 3 yrs of eruption

24

Sealant material shouldn't be stored near

In proximity to eugenol-containing products

25

Etchant contains what chemical

Phosphoric acid

26

Self cured sealants are supplied with two parts...

Base and catalyst

27

Why are sealants contraindicated on teeth with proximal decay

Sealant would break off because if filling placed to restore after sealant placed

28

What percent of low income children are sealants used

30

29

What is the most important factor in the success of a sealant

Proper placement/retention

30

What teeth are candidates for sealants

Teeth with deep pits and fissures preferably recently erupted teeth
