Question 1: glass ionomer

Answer:

characterized by its excellent adhesion to enamel and dentin, and its fluoride release

Question 2: insulating bases

Answer:

placed in a deep cavity preparation to protect the tooth from thermal shock

Question 3: calcium hydroxide

Answer:

cavity liner that protects the pulp from chemical irritation through its sealing abilities, stimulates production of secondary dentin, and is compatible with all types of restorative materials

Question 4: dental bonding

Answer:

aka dental adhesion, is the process of attaining solid and/or liquid contact of one material with another at a single margin

Question 5: desensitizer

Answer:

used to prevent or treat hypersensitivity, designed to seal the dentinal tubules, ideal for use under all direct and indirect restorations

Question 6: fluoride varnish

Answer:

gel-like substance is designed to release fluoride on enamel, root structure, and dentin structure.

Question 7: varnish

Answer:

seals dental tubules, reduces microleakage around a restoration, acts as a barrier to protect the tooth from highly acidic cements such as zinc phosphate

Question 8: Obliterating

Answer:

Removing something completely

Question 9: Hybrid

Answer:

Material that produces a similar outcome to its natural counterpart

Question 10: Polymerize

Answer:

To subject a material to the bonding process of two or more monomers

Question 11: Physical stimuli

Answer:

include thermal changes from hot and cold or electrical energy created by other metals that come into contact with the tooth

Question 12: Desiccate

Answer:

To remove all moisture from an item, or to dry out

Question 13: Biologic stimuli

Answer:

occur as a result of bacteria from saliva coming into contact with pulpal tissues, or when not all carious tooth structure was removed

Question 14: zinc phosphate cement

Answer:

an excellent material to use as a base because of its thermal insulation qualities

Question 15: varnish is placed

Answer:

after the liner is applied, within the entire preparation

Question 16: Thermal

Answer:

Relating to heat

Question 17: Sedative

Answer:

Having a soothing effect

Question 18: Etchant

Answer:

Chemical agent used to prepare a tooth surface for a dental material

Question 19: sedative bases

Answer:

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

Question 20: Most desensitizers contain

Answer:

hydroxyethyl methacrylate (HEMA) and glutaraldehyde, it is very important that this material is used sparingly, and that no material is allowed to contact soft tissue.

Question 21: Etching

Answer:

Process of cutting into a surface with the use of an acid product

Question 22: Insulating

Answer:

Preventing the passage of heat or electricity

Question 23: protective bases

Answer:

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

Question 24: polycarboxylate cements

Answer:

non-irritating to the pulp and can be placed under all types of direct and indirect restorations as a base

Question 25: Smear layer

Answer:

Very thin layer of debris on newly prepared dentin

Question 26: Mechanical stimuli

Answer:

include vibrations from a handpiece when the tooth is being prepared, as well as traumatic occlusion

Question 27: Eugenol

Answer:

Colorless liquid made from clove oil and used for its soothing properties

Question 28: zinc-oxide eugenol (ZOE) cannot be used under

Answer:

composite resins, glass ionomers, or other resin restorations because the eugenol in the liquid will effect the setting process of resin materials
