[2025-10-01T04:36:21.524372] [PI reasoning] **Defining bur blade accuracy**

I need to clarify that the ability of a bur blade to describe a complete circle during rotation is related to terms like "concentricity" or "runout." In dentistry, concentricity refers to the blade's rotational symmetry, meaning it should rotate in one plane. Runout assesses how all blades touch a perfect circle when rotated. From dental textbooks, I've learned that concentricity is measured using a special instrument and a dial gauge to check the consistency of the bur's main axis.

The search results aren't bringing up definitions, so I’ll rely on what I know about dental instruments. Concentricity refers to the ability of the bur blade to cut evenly, indicating whether the blades' tips are equidistant from the center axis when held stationary. It’s measured without rotation. Then there's the concept of runout, which relates to blade accuracy during rotation and how well the tips remain aligned in a plane as the bur spins.
