Maintaining good oral hygiene practices, such as regular brushing and flossing,
is the most effective way to prevent periodontal disease, as it reduces plaque
accumulation and gingival inflammation.
Subgingival curettage may result in all of of the following, except
1. root exposure
2. increased height of the gingiva
3. elimination of pockets
4. root sensitivity
Periodontics
Answer: 2
Subgingival curettage typically involves the removal of diseased tissue and can lead to root exposure and increased sensitivity. It may also help eliminate periodontal pockets. However, it does not result in an increased height of the gingiva; rather, it may lead to a reduction in gingival height due to tissue removal.
A characteristic of gingivitis is
1. vertical bone loss
2. swollen marginal tissue
3. wear of functional cusps
4. apical migration of the epithelial attachment
Periodontics
Answer: 2
Swollen marginal tissue is a hallmark of gingivitis, reflecting inflammation and
edema from plaque accumulation and irritants.
A hemiseptum is
1. one-wall defect
2. two-wall defect
3. three-wall defect
4. angular defect
Periodontics
Answer: 1
A hemiseptum refers to a periodontal defect with only one wall remaining, often
seen in sites of periodontal bone loss.
Which of the following is a problem relating to the improper use of a laterally positioned flap employed to cover a dehiscence?
1. Extreme patient discomfort
2. Presence of undetected occlusal trauma
3. Creation of a new dehiscence at the donor site
4. Severe infection
Periodontics
Answer: 3
If a laterally positioned flap is not properly designed or secured, it can lead
to complications such as tearing or failing to fully cover the dehiscence,
potentially causing a new dehiscence at the donor site.
Biobrane is a commercially available
1. Root matrix protein
2. Biodegradable membrane
3. Bone graft material
4. Non-bone graft membrane
Biobrane is a commercially available biodegradable membrane.
During activation of a scaling instrument, the facial surface of the blade and tooth surface should form an angle of
1. > 15 but < 45
2. > 30 but < 60
3. > 45 but < 90
4. > 90 but < 180
Periodontics
Answer: 3
During activation of a scaling instrument, the facial surface of the blade and tooth surface should form an angle of > 45 but < 90 degrees.
Treatment for ANUG in initial stages without systemic involvement is
1. Metronidazole and penicillin therapy
2. Gingivectomy and gingivoplasty
3. Both A and B
4. None of the above
Periodontics
Answer: 4
Treatment for ANUG in initial stages without systemic involvement is none of the above; typically, it involves debridement and possibly antibiotics.
