Dental Materials Theory Test 2 Part 1

The best was to check for properly mixed luting cement is to:

• Make sure that it is very thin and very runny

• Use the spatula to make sure that it is very grainy and sandy

• Use the spatula to create a thin line when raised

The smear layer is:

• They layer of dental stone that is smeared on the teeth

• A layer of cut tooth debris and/or bacteria

• Can be removed with light curing

What is the main principle of dental bonding?

• Where practitioners to get together to know each other more

• To seal margins

• To provide adhesion

• To add material to the incisal edges

What is an exothermic reaction?

• Cooking: adding heat

• Water leaving the material due to heat being generated from within

• Not applicable as this reaction does not occur with dental materials

What is the main ingredient in cement that produces and exothermic reaction?

• Water

• Calcium hydroxide

• Zinc phosphate

• Resin

What is the purpose of pigments in relation to composite resin?

• Adds to the hardness of the material

• Mimics the structure of natural enamel

• Varies as it affects the colour of the restoration

• Creates a nice glossy and translucent surface

Dycal being used for pulp capping is also know as:

• Polysulfide

• Cavity varnish

• Calcium hydroxide

• Calcium and magnesium

Which cement is a sedative to the pulp?

• zinc oxide eugenol (ZOE)

• Hybrid ionomer

• zinc phosphate

• glass ionomer

Which compressive strength is not applicable to ceramic materials?

• High compressive strength

• Low compressive strength

• High transverse strength

The most common form of curing resin bonding agents is:

• light curing

• self-curing

• dual curing

• all options listed
