Question

During forceps extraction, which part of the following is used as a dilating instrument?

• A. Alveolar socket
• B. Handle of the forceps
• C. Beak of the forceps
• D. Tooth

Hint:

In forceps extraction, the tooth acts as a wedge to expand the socket, while the forceps only apply and transmit force.

Answer 1

The Correct Option is D

Step 1: Understanding the mechanics of forceps extraction.
During tooth extraction using forceps, controlled forces such as buccal and lingual movements are appliedThese movements help expand the alveolar socket and rupture the periodontal ligament fibers
Step 2: Identifying the dilating component.
In this procedure, the tooth itself acts as a wedgeWhen force is applied, the root of the tooth presses against the bony walls of the socketThis causes expansion (dilatation) of the alveolar socket
Step 3: Role of forceps parts.
The beak of the forceps grasps the toothThe handle transmits forceHowever, neither of these directly dilates the socketThe dilatation occurs because the tooth root acts as a natural dilator
Step 4: Conclusion.
Therefore, during forceps extraction, the tooth functions as the dilating instrument
