Coronal Polish Certification Practice Test

Which part of the tooth should be polished first during coronal polishing?

1. Gingival margin

2. Cervical area

3. Middle third

4. Occlusal surface

The correct answer is: Cervical area

In coronal polishing, starting with the cervical area is important for several reasons. The cervical area is where the tooth meets the gum line, and it often accumulates plaque and stains that can be missed if other areas are polished first. By beginning at the cervical area, the dental professional ensures that any debris or accumulations in this critical zone are effectively removed before moving on to other parts of the tooth. Polishing this area first also helps to establish control and technique, as it requires careful handling to avoid damaging the delicate gum tissue. Once the cervical area is clean, the practitioner can proceed to the other sections of the tooth, such as the middle third, occlusal surface, and gingival margin, with a clearer approach since the potentially problematic area has been addressed. This methodical approach not only contributes to better overall oral hygiene but also reinforces the importance of a thorough and systematic procedure during coronal polishing.
