What is a burnisher used for in dental procedures?

1. To place a base or temporary filling

2. To smooth amalgam

3. To add support to a tooth

4. To measure pocket depth

The correct answer is: To smooth amalgam

A burnisher is a dental instrument primarily used to smooth the surface of amalgam restorations after they have been placed in a cavity. This smoothing process enhances the restoration's finish and reduces the likelihood of plaque accumulation on the surface, thereby improving overall oral hygiene and aesthetics. The smooth surface also helps with the longevity of the restoration and the comfort of the patient's bite. Using a burnisher to smooth amalgam is essential in achieving a polished look and feel for the filling, helping to ensure that the restoration fits well with the surrounding tooth structure. This is critical for both functionality and patient comfort. The other options touch on different dental tools and procedures but do not accurately describe the primary function of a burnisher. For example, placing a base or temporary filling, providing support to a tooth, and measuring pocket depth involve other specific instruments and techniques, but they do not relate to the primary role of a burnisher in smoothing materials like amalgam.
