CRCST Practice Exam

Which material is used to test the sharpness of Osteotomes?

1. Plastic dowel rod

2. Index Card

3. Pencil

4. Metal wire

The correct answer is: Plastic dowel rod

Osteotomes are surgical instruments used for cutting and preparing bone during surgeries. To test the sharpness of Osteotomes, a material that closely mimics the density and resilience of bone needs to be used. A plastic dowel rod is the most appropriate material for this purpose because it provides a more realistic simulation of cutting through bone compared to the other options. Index cards, pencils, and metal wires do not have the same consistency or properties as bone, and therefore would not provide an accurate assessment of the sharpness of Osteotomes. It is essential to use a material that can effectively gauge the cutting ability of these instruments to ensure they are in optimal condition for surgical procedures.
