dental liners, bases, and bonding systems

Question 1

physical stimuli

Answer 1

thermal changes

Question 2

mechanical stimuli

Answer 2

vibration from hand pieces or biting

Question 3

chemical stimuli

Answer 3

occur as a result of acidic materials including saliva touching the pulp that is exposed

Question 4

biologic stimuli

Answer 4

bacteria (like from salvia) touching the pulpal tissues

Question 5

calcium hydroxide

Answer 5

a cavity liner most commonly used as it stimulates the growth of secondary dentin and is compatible with all restorative materials

Question 6

glass ionomer liner

Answer 6

used to form a strong bond to dentin to reduce micro leakage while also reducing sensitivity

Question 7

varnish

Answer 7

seals dental tubules and used to protect the tooth from acidic bases or cement (like zinc phosphate)

Question 8

desensitizing agent

Answer 8

A type of sealer used to protect the tooth from hypersensitivity, seals dental tubules

Question 9

protective base

Answer 9

placed when necessary to protect the pulp before the restoration is placed

Question 10

insulating base

Answer 10

placed in a deep portion to protect the tooth from thermal shock

Question 11

sedative base

Answer 11

help soothe the pulp that has been damaged by decay or irritated during the process of removing the decay

Question 12

zinc oxide-eugenol (ZOE)

Answer 12

used as an insulating and a sedative base

cannot be used under composite, glass ionomers or any resin because the eugenol in the liquid affects the setting process of the resin

Question 13

zinc phosphate

Answer 13

great insulating base though can irritate the pulp so it must be placed with a liner

Question 14

polycarboxylate

Answer 14

protective and insulating base and can be used under all types of direct and indirect (especially metal) and is non irritating to the pulp

Question 15

glass ionomer

Answer 15

adheres to enamel and dentin very well while releasing fluoride

Question 16

hybrid layer

Answer 16

a thin layer created between dentin and the adhesive resin that seals the space between the tooth and restoration
