Periodontics - 3 Questions

1
Periodontics
A periodontal probe measures
1) Amount of gingival recession
2) Amount of attachment loss
3) Amount of gingival inflammation
4) Width of attached gingiva

📝 Explanation:

Probing depth + gingival recession together indicate clinical attachment loss, which is the key measurement in periodontal diagnosis.

When doing instrumentation near the cementoenamel junction, cementum completely removed because it is
1. very thin in this area
2. usually softer than subgingival calculus
3. necrotic in the pocket
4. all of the above

📝 Explanation:

The cementum near the cementoenamel junction (CEJ) is indeed very thin, making it more susceptible to removal during instrumentation. Additionally, cementum can be softer than subgingival calculus, and in cases of periodontal disease, it may become necrotic.

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

📝 Explanation:

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.
