Q

What steps does the ultrasonic technique include?

Work in various directions
Use oblique or corkscrew tips to reach furcations
Avoid pressing the scaler tip on the tooth surface too hard

32
Q

What position is useful for maxillary posterior teeth?

A

An extraoral finger rest
Fingers should rest on the teeth for maxillary anterior & mandibular areas
A stable fulcrum is not always necessary

33
Q

Engage

A

Activate the tip of the instrument & direct the tip subgingivally
Water lavage will facilitate a comfortable entry into the sulcus

34
Q

Neutral

A

A balanced instrument grasp
The instrument should feel balanced in the hand with no pull from the cord
Use a light pen or modified pen grasp

35
Q

Technique

A

Brush away the calculus

Using sweeping cross strokes

36
Q

Adaptation

A

Ultrasonic & sonic instruments are active on at least two sides when in contact with the tooth surface
The side of the tip is held parallel to the tooth surface
The end of the tip should not be adapted to the tooth surface at a 90-degree angle

37
Q

Light touch

A

Apply extremely light pressure

38
Q

What settings should be used for the broad-based, beavertail-type tips?

A

Higher power settings

39
Q

What should the power setting be decreased to when thin subgingival tips are used?

A

Lower settings

40
Q

What does failure to decrease the power setting cause?

A

Fracturing of the tip or render it ineffective because the tips are manufactured to operate in optimal frequency ranges

41
Q

Rather than scaling teeth, rotary scaler burs, end up doing what to calculus, and leading to a periodontal abscess?

A

Burnishing calculus

42
Q

What should be used to measure the depth of the sulcus or pocket?

A

A periodontal probe

43
Q

How should the periodontal probe be held for an accurate reading?

A

Parallel to the long axis

44
Q

What does holding the probe at an angle result in?

A

An inaccurate measurement

45
Q

If the marginal gingiva is at the normal cementoenamel junction, the probed depth will correspond with what?

A

Attachment loss

46
Q

If a previous recession of the gingiva has occurred and the marginal gingiva has moved apically, the pocket depth will be less than what?

A

The actual loss of attached gingiva

47
Q

What happens if gingival hyperplasia and a pseudopocket are present, the probed depth will be what?

A

Greater than the actual attachment loss

48
Q

When charting, what is the recommended order?

A

Buccal of right posterior maxilla
Lingual of the left posterior maxilla
Lingual of left posterior mandible
Buccal of the right posterior mandible

49
Q

What should be used to remove the calculus below the gumline?

A

A curette or select ultrasonic scaler

50
Q

What should be used to scale and remove calculus below the gumline?

A

Ultrasonic scalers with subgingival tips

51
Q

What is an extremely important part of the dental procedure?

A

The removal of subgingival calculus

52
Q

What is the preferred method for holding hand instruments?

A

The modified pen grasp

53
Q

Where are the thumb and forefinger placed on the instrument with a modified pen grasp?

A

At the junction of the handle and shank of the instrument

54
Q

When using a modified pen grasp, where is the ring finger placed?

A

Held straight and placed on the surface closest to the tooth being worked on.

55
Q

What is adapted to the tooth root surface?

A

The curette

56
Q

What happens if the instrument does not fit the curvature of the tooth?

A

The opposite end of the instrument is adapted

57
Q

What position is the closed position?

A

The face of the curette should face the root surface as it is inserted into the pocket

58
Q

What position is the open position?

A

The instrument is moved over the calculus and then repositioned so that the cutting surface is under the calculus ledge

59
Q

What is used to evaluate the tooth surface while checking for subgingival calculus?

A

An explorer

60
Q

What are two techniques used to detect plaque and calculus?

A

Air-drying

Application of disclosing solution

61
Q

Why should air-drying not be used if the integrity of the periodontium is in question?

A

Because air being blown into tissues can be trapped in the subcutaneous tissues or possibly enter the bloodstream

62
Q

What are the use of a proxy angle and abrasive paste?

A

Mechanical polishing

63
Q

What does polishing with an electric or air-powered polisher do?

A

Removes any plaque that may have been missed and smooths the tooth surface

64
Q

What is the most economic means of making prophy paste?

A

To mix flour pumice with a slight amount of water

65
Q

What speed are teeth polished with?

A

3000 to 8000 rpm

66
Q

What does air polish use?

A

Air, water, powder projection

67
Q

What are the advantages of air polishing when compared to a mechanical polisher?

A 
Faster and less demanding
Reducing the operator’s hand fatigue
Less abrasive than abrasive pastes
No production of heat 
Gives better access to the teeth 
No direct contact with the dental surface
68
Q

What are the disadvantages of air polishing when compared to a mechanical polisher?

A

More expensive

Can be messier

69
Q

What flushes out trapped debris and oxygenates the intrasulcular fluids?

A

Gentle irrigation

70
Q

Should the full-strength disinfectant chlorhexidine that is commonly found in veterinary hospitals be used?

A

No

71
Q

What are the two types of sealers available?

A

Sanos

OraVet

72
Q

Why should radiographs be taken?

A

To evaluate the dental and bony structures for periodontal bone loss, root canal disease, other conditions

73
Q

What is the last step to complete prophy?

A

Home-care instruction
