A young adult shows non-fluctuant, tender and red swelling in the marginal gingival lesion. This is most likely
1. Periodontal abscess
2. Periapical abscess

Efficient way of calculus removal is
1) A relaxed instrument grasp and light lateral working strokes
2) A tight instrument grasp and light lateral working strokes
3) A tight instrument grasp and firm lateral working strokes
4) None of the above
Periodontics
Answer: 3
Explanation:
For effective calculus removal, a tight instrument grasp combined with firm lateral working strokes is essential. This technique allows for better control and application of force, which is necessary to effectively dislodge calculus from the tooth surface.

2. CE junction
3. Exposed root surfaces
4. Deep periodontal pocket
