Angulation of a periodontal instrument refers to the
1) Angle between the face of the blade and the shank
2) Angle between the shank and the shaft
3) Angle between the face of the blade and the tooth surface
4) Angle between the shank and the tooth surface
Periodontics
Answer: 3
In periodontal instrumentation, angulation is crucial for effective scaling and root planing. The angulation refers to the relationship between the face of the instrument's blade and the surface of the tooth being treated. Proper angulation allows for optimal removal of calculus and plaque. The other options refer to different relationships that are not specifically defined as "angulation" in the context of periodontal instruments.
The most effective method of preventing periodontal disease in the general population is
1. oral hygiene
2. balanced diet
3. fluoride therapy
4. analgesics and antibiotics
Periodontics
Answer: 1
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.
Slight gingival recession on normally placed canine is noted due to inflammation. After through scaling and root planing it is free of inflammation. Treatment of choice
1) Laterally positioned graft
2) Free gingival graft
3) Coronally displaced graft
4) Maintenance and recall visits
Periodontics
Answer: 4
1) Laterally positioned graft: This technique is used when there is a loss of
interdental papilla, which may occur due to periodontal disease or trauma.
2) Free gingival graft: This involves the transfer of a piece of tissue from the
palate to the affected area to cover the exposed root surface and increase the
zone of attached gingival tissue.
3) Coronally displaced graft: This technique involves moving the existing
gingival tissue coronally over the exposed root to cover it.
4) Maintenance and recall visits: After the resolution of inflammation through
scaling and root planing, if the recession is minimal and the tooth is not at
risk of further damage, regular maintenance and recall visits may be sufficient
to monitor the area.
Since the question mentions that the tooth is normally placed and the issue is
resolved after scaling and root planing, the correct answer is 4) Maintenance
and recall visits to ensure the area remains healthy and monitor for any
recurrence of recession.
