What is the function of a periosteal elevator in dental procedures?

1. To remove tooth fragments from the socket

2. To detach the periosteum from bone

3. To shape dentures for better fit

4. To keep the mouth open during treatment

The correct answer is: To detach the periosteum from bone

The function of a periosteal elevator in dental procedures is to detach the periosteum from bone. The periosteum is a dense layer of vascular connective tissue that covers the outer surface of bones, and it plays a vital role during surgical and dental operations. By using a periosteal elevator, dental professionals can gently lift this connective tissue away from the bone to gain better access to the underlying structures. This is particularly important in procedures such as tooth extractions, implants, and other oral surgeries, where visibility and access to the surgical site are critical to ensure safety and effectiveness. The other choices pertain to different tools or procedures that either don't involve the periosteum or serve different functions entirely in dental practice, such as extracting debris or maintaining mouth openness, but they do not apply to the specific actions of a periosteal elevator.
