22
Q

Clinical applications for etching and bonding system:

A

Remove plaque and debris prior to the bonding process.

Remove the smear layer with the use of etchant.

Rinse and dry the tooth surface structure( avoid overseeing etched teeth.)

Cover all surfaces with bonding solution (too much bonding is better than too little)

Avoid contamination from saliva ( the entire procedure will need to be redone if contamination occurs.)

Allow for maturation of bonding material. (Maturation needs to occur before restoration is considered complete)

23
Q

Enamel bonding

A

Used when a bind is needed in the intact enamel surface.

24
Q

What is enamel bonding used for?

A

Orthodontic brackets, dental sealants, and resin bonded veneers and bridges.

25
Q

For an amalgam filling with a deep cavity what should be placed first?

A

Base

26
Q

Dental cements

A

This brittle material is made by mixing a liquid with a powder. It acts as a luring agent, protects or lines the cavity preparation.

27
Q

Type 1 classification

A

Luting agents, temporary or permanent cements.

28
Q

Type II Classification.

A

Restorative material, such as glass ionomer.

29
Q

Type III classification

A

Liners or bases placed with cavity preparation.

30
Q

Luting agents

A

Viscous material placed into dental prosthesis that secures the prosthesis securely to the tooth via chemical bonding.

31
Q

Permanent cements

A

This is used to bond gold and ceramic restorations. Such as inlays, onlays, crowns, bridges, veneers, orthodontic fixed appliances.

32
Q

Temporary cements

A

This is used until a restoration would need to be removed as a result of sensitivity or other symptoms. Also used for provisional coverage

33
Q

Mixing

A

Before mixing, follow the manufacturers directions.

Measure the liquid and powder in the amount needed for use.

Separate the powder and liquid to make space for mixing.

Separate the powder into smaller portions.

When increment sizes vary, smaller increments are incorporated first.

Mix each portion of power into liquid and mix until consistent.

34
Q

Humidity

A

Premature exposure to warm temp or humidity can result in too much moisture in the mix or not enough water in the liquid.

35
Q

Powder to liquid ratio

A

Mixing incorrect amounts of water and powder will result in inconsistency

36
Q

Temperature

A

Some cements undergo an exothermic reaction.

37
Q

Types of cements:

A

Glass ionomer

Composite resin

Polycarboxylate

Zinc phosphate

38
Q

Zinc oxide eugenol (ZOE)

A

Another type of cement, that comes as a paste or liquid.

39
Q

ZOE liquid

A

Eugenol, H2O, acetic acid, zinc acetate, and calcium chloride

40
Q

Powder ZOE

A

Zinc oxide, magnesium oxide, and silica

41
Q

Type I ZOE (paste)

A

Recommended for temporary restorations due to lack of strength.

42
Q

Type II ZOE (liquid/powder)

A

Used for permanent cementation of cast restorations due to strength and durability characteristics

43
Q

Polycarboxylate cement

A

Also known as polyacrylic cement. This material can be used as a cement for cast restorations, an insulation base under amalgam, or as an intermediate restoration

44
Q

Polycarboxylate liquid

A

Polycrylic acid, itaconic acid, maleic acid, tartaric acid, and water

45
Q

Polycarboxylate powder

A

Zinc oxide

46
Q

Glass ionomer liquid

A

Itaconic acid, tartaric acid, maleic acid, and water

47
Q

Glass ionomer powder

A

Zinc oxide, aluminum oxide, and calcium

48
Q

Glass ionomer type I

A

Used for cementing metal restorations and bonded orthodontic brackets

49
Q

Glass ionomer type II

A

Used for class V restorations of areas or recession.

50
Q

Glass ionomer type III

A

Designed for restoration liners or dentin bonding agents

51
Q

Glass ionomer benefits:

A

The powder is made up of acid soluble calcium. The slow release of fluoride helps inhibit recurrent decay.

It is less irritating to the pulp than many other types of cement.

It has lower solubility in the mouth.

It adheres to a slightly moist tooth surface.

It allows easier seating of restorations because it has a thin film thickness.

52
Q

What is composite resin used for?

A

Cement ceramic or resin onlays or onlays.

Cement porcelain or ceramic veneers.

Cement orthodontic bands.

Bond orthodontic brackets.

Cement all metal castings.

53
Q

What instruments can remove cement?

A

Mouth mirror

Explorer

Excavator

Fulcrum

Dental floss
