Bone graft procedures are most successful in treating
1) Furcation involvements
2) Deep, two-wall craters
3) Narrow three-wall defects
4) None of the above
Periodontics
Answer: 3
Bone graft procedures are most successful in treating narrow three-wall defects. These are defects that extend from the crest of the alveolar bone to the alveolar crest and involve only one surface of the tooth root. The success of a bone graft in such cases is due to the presence of three walls of intact bone that can provide stability and support for the graft material, allowing for predictable and effective regeneration of the missing bone tissue.
Pyogenic granuloma is
1. Granulation tissue overgrowth
2. Capillary haemangioma
3. Sarcoidosis
4. Tuberculoid leprosy
Periodontics
Answer: 1
Pyogenic granuloma is a granulation tissue overgrowth.
Subgingival calculus is highest in
1) Lower anterior region
2) Lower bicuspid region
3) Lower molar region
4) Upper molar region
Periodontics
Answer: 1
Subgingival calculus
is often found in the lower anterior region due to the
anatomy and position of the teeth.
An acute periapical abscess can be differentiated from an acute periodontal abscess most reliably by the
1. degree of tooth mobility
2. nature of the swelling
3. blood and urine examination
4. response to periodontal probing
Periodontics
Answer: 4
The response to periodontal probing is a reliable method to differentiate
between an acute periapical abscess and an acute periodontal abscess. An acute
periapical abscess typically does not show significant probing depth changes,
while a periodontal abscess may show increased probing depths due to periodontal
tissue involvement.
Which of the following conditions gingivectomy is contraindicated:
1. Gingival sulcus beyond mucogingival junction.
2. Enlargement of the gingival.
3. Papillary enlargement.
4. Enlargement due to acute systems disease.
Periodontics
Answer: 1
Gingivectomy is a surgical procedure used to remove excess gingival tissue. It is typically performed when the enlargement of the gingival tissue is due to chronic inflammation or other local factors. However, if the enlargement is caused by an acute systemic disease, the surgical intervention could potentially exacerbate the underlying condition or lead to complications.
Following the application of disclosing solution on teeth, a patient can remove plaque most effectively by using
1. dental floss
2. a strong mouthwash
3. a water irrigating device
4. a soft bristle brush
Periodontics
Answer: 4
A soft bristle brush is the most effective tool for removing plaque after the application of a disclosing solution. It allows for thorough cleaning of the tooth surfaces, including areas that may be difficult to reach with other methods.
Periodontal pack is least effective in
1) Providing splinting action
2) Haemostatic mechanism
3) Pain elimination
4) Antimicrobial action
Periodontics
Answer: 3
Periodontal packs are primarily used for their antimicrobial, haemostatic, and splinting properties. While they provide a good antimicrobial environment and can aid in haemostasis, they are not typically used for pain elimination. The main purpose of a periodontal pack is to deliver medication directly to the periodontal pocket and help stabilize the gum tissue around the teeth. Pain relief is generally managed through other means such as analgesics or local anesthetics.
Which of the following drug regimens is not likely to influence periodontal therapy?
1. Propranolol
2. Antihistamine
3. Sodium warfarin
4. Corticosterone
Periodontics
Answer: 2
Antihistamines are not typically associated with significant effects on
periodontal therapy. In contrast, propranolol (a beta-blocker), sodium warfarin
(an anticoagulant), and corticosteroids can all influence periodontal health and
treatment outcomes.
