A

Ultrasonic Scaler

29
Q

Indications for use of an ultrasonic scaler include the following:

A
  • Removal of supragingival calculus and stains
  • Removal of subgingival calculus, attached plaque, and endotoxins from the root surface
  • Cleaning of furcation areas

  • Removal of orthodontic cements, or debonding
  • Removal of overhanging margins of restorations
30
Q

Contraindications to use of the ultrasonic scaler include the following general health considerations:

  • communicable diseases
  • patients susceptible to infection
  • respiratory problems
  • swallowing difficulty
  • cardiac pacemaker
31
Q

these oral conditions may be contraindications to the use of ultrasonic scalers

A
  • Demineralized areas
  • Exposed dentinal surfaces.
  • Restorative materials
  • Titanium implant abutments.
  • Narrow periodontal pockets.
32
Q

procedure, commonly referred to as prophy or cleaning, is the complete removal of calculus, soft deposits, plaque, and stain from all supragingival and unattached subgingival tooth surfaces

A

Dental Prophylaxis

33
Q

A ________ is indicated for patients with healthy gingiva as a preventive measure and is most often performed during recall appointments.

A

prophylaxis

34
Q

The goal of ________ is to remove deposits on the tooth and reduce the bioburden within the pocket.

A

35
Q

done to remove supragingival calculus from the tooth surface with periodontal scalers.

A

scaling

36
Q

Curettes are used to remove ____ and _____ calculus.

A

supragingival and subgingival calculus

37
Q

Areas on the root surface may remain rough after calculus removal because the cementum has become _____

A

necrotic

38
Q

follows scaling procedures to remove any remaining particles of calculus and necrotic cementum embedded in the root surface.

A

Root planing

39
Q

After root planing, the surfaces are smoother and are free from _______ Smooth root surfaces are easier for the patient to keep clean.

A

endotoxins

40
Q

involves scraping or cleaning the gingival lining of the pocket with a sharp curette to remove necrotic tissue from the pocket wall.

A

gingival curettage
or
subgingival curettage

41
Q

a particularly useful antibiotic for the treatment of early-onset periodontitis,

A
