Polishing bur have.. More than 12 blades

Polishing bur have:

  • a. Less than 6 blades.
  • b. 6-7 blades.
  • c. 10-12 blades.
  • d. More than 12 blades.***

the most likely answer is: c. 10-12 blades

The number of blades in a polishing bur can vary depending on its intended purpose. Here's a breakdown of the options:

a. Less than 6 blades:

This isn't common for polishing burs. They usually have more blades for smoother finishing and polishing.

b. 6-7 blades:

This is a possibility for some types of polishing burs, especially for initial shaping and pre-polishing.

c. 10-12 blades:

This is the most common range for polishing burs. These burs provide efficient and smooth polishing for various materials.

d. More than 12 blades:

These are often called "superfinishing" burs and are used for achieving the highest level of surface smoothness and shine.
Therefore, the most likely answer is: c. 10-12 blades

However, it's important to note that the ideal number of blades can depend on the specific bur design, material being polished, and desired finish.

If you can provide more context about the type of polishing bur you're interested in, I can give you a more precise answer.
