Question 1

Which instrument is specifically designed to detach the periosteum from the underlying bone?

Accepted Answer

Periosteal elevator

Answer

The periosteal elevator is a surgical instrument used to separate and retract the periosteum (the thin membrane covering the bone) from the surface of the bone. This action exposes the bone for procedures like extractions or implant placement.

Question 2

To maintain a sterile field, where must the hands of a surgically scrubbed assistant be kept?

Accepted Answer

Above the waist and in front of the body

Answer

Maintaining a sterile field is paramount in oral surgery. The area from the waist to the shoulders in front of the body is considered the sterile zone for scrubbed personnel, and hands must be kept within this area to prevent contamination.

Question 3

What is the primary purpose of placing a sterile 2x2 gauze over an extraction site and having the patient bite down?

Accepted Answer

To help a blood clot form and stop the bleeding

Answer

Applying firm, consistent pressure with a sterile gauze pad over the extraction site helps control bleeding and promotes the formation of a stable blood clot. This clot is essential for proper healing and preventing complications like a dry socket.

Question 4

An instrument used to smooth the surface of the bone after an extraction to remove sharp edges is called a:

Accepted Answer

Bone file

Answer

A bone file is a double-ended instrument with serrated surfaces used in a push-pull motion to smooth rough margins of the alveolar bone. This process, called alveoplasty, ensures the tissue heals smoothly and comfortably.

Question 5

Which type of suture material is designed to be absorbed by the body and does not require removal?

Accepted Answer

Gut

Answer

Absorbable sutures, such as plain or chromic gut, are made from materials that the body's enzymes can break down and absorb over time. This eliminates the need for a follow-up appointment for suture removal, which is common for non-absorbable materials like silk or nylon.
