Q

provides rapid calculus removal and reduces hand fatigue for the operator.

A

Ultrasonic Scaler

28
Q

works by converting very-high-frequency sound waves into mechanical energy in the form of extremely rapid vibrations (20,000 to 40,000 cycles per second) at the tip of the instrument.

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 deposits before periodontal surgery
• 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:

A

-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

debridement

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

42
Q

antibiotic less effective against periodontal disease infection because many periodontal pathogens are resistant to it.

A

penecillin

Q

type of mouth rinses have been shown to reduce bleeding by delaying bacterial growth within the periodontal pockets.

Excisional Surgery

48
Q

the surgical removal of diseased gingival tissue. This procedure is performed when it is necessary to reduce the depth of the periodontal pocket and when fibrous gingival tissue must be removed.

involves the surgical reshaping and contouring of gingival tissues.

A

Gingivoplasty

51
Q

performed when excisional surgery is not indicated. In thissurgery, the tissues are not removed but are pushed away from underlying tooth roots and alveolar bone

A

periodontal flap surgery

52
Q

periodontal surgery that involves modification of the supporting bone. It is performed to eliminate pockets, remove defects, and restore normal contours in the bone.

A

Osseous Surgery

53
Q

periodontal surgeries that involve bone

A

osteoplasty and ostectomy

54
Q

additive bone surgery, bone is contoured and reshaped.

A

Osteoplasty

55
Q

subtractive bone surgery, bone is removed. This procedure is necessary when the patient has large exostoses (bony growths)

A

Ostectomy

56
Q

is a surgical procedure that is designed to expose more tooth structure for the placement of a restoration such as a crown.

A

Crown Lengthening

57
Q

indications for crown lengthening include

A

(1) a tooth that is fractured close to the gingival margin
(2) subgingival caries

58
Q

this graft is used to move gingivae from an adjacent tooth or edentulous area to a recipient site on another tooth

A

pedicle graft

59
Q

this type of graft has a donor site that is located away from the grafted site. Thus the blood supply is not attached to the graft and depends on the recipient site.

A

Free Gingival Soft Tissue Graft

60
Q

serves as a bandage over the surgical site.

A

periodontal dressing (periopack)

61
Q

Periodontal dressings, also known as periopacks, are used for the following purposes:

A

• hold the flaps in place
• protect newly forming tissues
• minimize postoperative pain, infection and hemorrhage
• protect the surgical site from trauma during eating and drinking
• To support mobile teeth during the healing process

62
Q

most widely used type of periodontal dressing.

A

Noneugenol Dressing

63
Q

procedures used to correct defects in the shape, position, or amount of gingival tissue

A

Periodontal plastic surgery

64
Q

Periodontal applications of lasers on soft tissue include the following:

A

• Removal of tumors and lesions
• Vaporization of excess tissues
• Removal of or reduction in hyperplastic tissues
