Luting Agents

Question 1

This luting agent has adequate strength and high solubility, it may cause moderate pulp irritation but offers easy removal of excess cement and crown if needed

Answer 1

zinc phosphate

Question 2

What are the two things that make up zinc phosphate

Answer 2

powder; zinc oxide

liquid; phosporic acid

Question 3

This is used to mix the zinc phosphate by increasing the working time of the cement by slowing the exothermic chemical reaction

Answer 3

a cool glass slab

Question 4

What are two advantages and one disadvantage to increasing the powder to liquid ratio of zinc phosphate

Answer 4

advantages; improves strength and reduces solubility

disadvantages; increases viscosity

Question 5

What is the biggest thing to do when mixing the powder and liquid of the zinc phosphate

Answer 5

use incrementation

Question 6

What should you do if you have improper zinc phosphate cement thickness

Answer 6

discard the cement and start over; do not add more liquid

Question 7

This luting agent is biocompatable with some adhesion to tooth structure, it has very high viscosity and a short working time and is harder to remove than zinc phosphates

Answer 7

Zinc polycarboxylate

Question 8

What is the main disadvantage of GI

Answer 8

its susceptibility to motor contamination and subsequent solubility if exposed to water during the initial setting period, its also susceptible to dehydration

Question 9

What does GI release

Answer 9

fluoride

Question 10

resin-modified glass ionomers have an increase in this property compared to zinc phosphates, polycarboxylates and GI

Answer 10

strength

Question 11

This is the adhesive choice for resin composite inlays and onlays, all ceramic inlays and inlays, and veneers

Answer 11

composite resin

Question 12

This adheres to multiple substrates, has high strength, insolubility to the oral environment and shade matching potential

Answer 12

composite resin

Question 13

Composite resin bonds chemically to what

Answer 13

resin composite restorative materials and silanated porcelain

Question 14

Composite resin increases this is ceramic materials that can be etched or silanated

Answer 14

fracture

Question 15

Composite resin demonstrates good what to sandblasted metal alloy as a result of micro mechanical retention

Answer 15

bond strength

Question 16

What part of the casting will you apply cement to

Answer 16

the axial walls

Question 17

NEVER COAT what with the cement

Answer 17

the prepared tooth

Question 18

If the casting can not be completely seated, what should you do

Answer 18

remove it immediately!!

Question 19

Once the cement has sufficiently set, what is the only way to remove the casting

Answer 19

cut it off

Question 20

What are three causes of incomplete seating

Answer 20

luting agent too thick
insufficient seating force applied along POW
binding occurred between the axial walls of the preparation and the casting
