Adhesives and Dental Cements

Question 1

material that bonds 2 surfaces; area must be clean and dry

Answer 1

adhesives

Question 2

seeping/leaking of bacteria between the tooth and restoration

Answer 2

micro leakage

Question 3

heating/cooling causing expansion or contraction

Answer 3

percolation

Question 4

roughens surface so adhesive has something to stick to (35-37% orthophosphoric acid for 15 to 30 secs)

Answer 4

etching

Question 5

harder to bond to than enamel so usually have more steps

Answer 5

dentin

Question 6

hold/glue to the tooth surface and protect dentin or pulp

Answer 6

cements

Question 7

what are examples of cements

Answer 7

luting agents, liners, bases, restorations, perio packs, fill root canals, cement ortho appliances

Question 8

what is the luting consistency

Answer 8

1” string

Question 9

adhesion = ____________ = less caries, sensitivity, stain, damage from percolation

Answer 9

no microleakage

Question 10

thin; secondary dentin formation, reduces dentinal sensitivity, protects pulp (chemical)

Answer 10

liners

Question 11

what are examples of liners

Answer 11

calcium hydroxide or glass ionomers

Question 12

thicker to replace dentin protects pulp (thermal)

Answer 12

bases

Question 13

what are examples of bases

Answer 13

glass ionomers

Question 14

IRM (ZOE with reinforcement material)

Answer 14

temporary filling

Question 15

ZOE

Answer 15

temporary cement

Question 16

COE (Zinc Oxide MINUS eugenol)

Answer 16

perio packs

Question 17

rarely used: seals tubules under amalgams

Answer 17

cavity varnish

Question 18

adheres to dentin, enamel, and metal; strong luting cement; good compressive strength; release fluoride

Answer 18

zinc polycarboxylate pros

Question 19

short working time

Answer 19

zinc polycarboxylate cons

Question 20

promotes secondary dentin formation and releases fluoride

Answer 20

calcium hydroxide

Question 21

fluoride releasing restorative material made with silver and glass ionomer

Answer 21

cermet

Question 22

does not release fluoride; does not chemically bond to the tooth; irritating to the pulp because it is very acidic; produces heat

Answer 22

zinc phosphate cons

Question 23

very very strong

Answer 23

zinc phosphate pros

Question 24

when you see “phosphate” what should you remember

Answer 24

etch=acidic=bad

Question 25

what’s the #1 choice for cement type

Answer 25

glass ionomer

Question 26

considered an excellent liner or base; release fluoride; bonds well to the tooth structure and to composite resins; high biocompatibility; good thermal insulators, similar thermal expansion to tooth structure; low solubility

Answer 26

glass ionomers pros

Question 27

need very dry surface

Answer 27

glass ionomer cons

Question 28

glass ionomer + composite

Answer 28

composer

Question 29

what does ZOE stand for

Answer 29

zinc oxide eugenol

Question 30

obtudent effect = sedative; antimicrobial properties

Answer 30

ZOE pros

Question 31

only used as temp cement; does not adhere to enamel and dentin; shouldn’t be used under resin

Answer 31

ZOE cons

Question 32

what cements are fluoride releasing

Answer 32

cermet, composer, glass ionomers, zinc polycarboxylate, ZOE, calcium hydroxide

Question 33

what cements do not release fluoride

Answer 33

zinc phosphate
