HOSA Dental Terminology Practice

What is the unique characteristic of finishing burs?

1. They are used to cut tooth structure

2. They recreate tooth anatomy

3. They are intended for initial cavity preparation

4. They are used for extreme precision in cutting

The correct answer is: They recreate tooth anatomy

Finishing burs are specifically designed to refine the surfaces of dental restorations and to recreate or restore the natural anatomy of a tooth after material has been placed. Their unique characteristic lies in their ability to smooth and polish surfaces, allowing dentists to achieve a final contour that mimics the original tooth’s shape, texture, and function. This is crucial in ensuring that restorations blend seamlessly with the surrounding dentition, leading to improved aesthetics and patient satisfaction. The other options describe functions or characteristics associated with other dental instruments, such as cutting into tooth structure or preparing cavities, which are not the primary roles of finishing burs.
