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.

Most commonly used desensitising agent
1) Iontophoresis
2) 2 % Fluoride
3) Formalin
4) Sodium hypochloride
Periodontics
Answer: 2
2% fluoride is one of the most commonly used desensitizing agents in dentistry. It works by strengthening enamel and reducing the permeability of dentin, which helps alleviate sensitivity in teeth. Fluoride treatments are widely used in clinical practice to manage dentinal hypersensitivity effectively.

Crater-like gingival deformities are seen in
1. ANUG
2. JP
3. Chronic gingivitis
4. Adult periodontitis

Which of the following groups of fibers belongs to the gingivodental group and not to the periodontal ligament?
1. Circular
2. Alveolar crest
3. Transseptal
4. Horizontal
Periodontics
Answer: 1
The circular fibers are part of the gingivodental group and are located in the
marginal gingiva, encircling the teeth. In contrast, the alveolar crest,
transseptal, and horizontal fibers are part of the periodontal ligament.
