Coronal Polish Certification Practice Test

For which of the following surfaces is coronal polishing primarily performed?

1. The gingival margin

2. The coronal surfaces of the teeth

3. The interproximal spaces

4. The root surfaces

The correct answer is: The coronal surfaces of the teeth

Coronal polishing is primarily performed on the coronal surfaces of the teeth, which include the anterior and posterior tooth crowns above the gum line. This procedure is intended to remove plaque, stains, and debris from these surfaces, contributing to both aesthetic and oral health benefits. The coronal surfaces are the areas that are most visible and, therefore, are the focus during dental hygiene practices aimed at achieving a polished and clean appearance, as well as preventing caries and periodontal disease. Focusing on other options, the gingival margin is not the primary target for coronal polishing because this procedure is not intended to clean the area where the gum meets the tooth; rather, it is more about the tooth surface itself. Interproximal spaces require different cleaning techniques, such as flossing or the use of interproximal brushes, to effectively remove plaque and debris between the teeth. Root surfaces also demand specialized care, particularly in areas where periodontal disease is present, and polishing is not typically performed on root surfaces due to the risk of additional damage or sensitivity. Therefore, the correct surface for coronal polishing is indeed the coronal surfaces of the teeth.
