Coronal Polish Certification Practice Test

What clock positions do operators generally use when polishing teeth?

1. 6-9

2. 9-12

3. 1-3

4. 3-6

The correct answer is: 9-12

Polishing teeth effectively requires an understanding of the positioning techniques that facilitate access to various surfaces of the teeth. The choice of clock positions is essential in ensuring that the operator can achieve optimal visibility and accessibility while maintaining proper ergonomic posture. The 9-12 clock position is widely accepted among dental professionals for polishing procedures. This positioning allows the operator to approach the patient's mouth from an angle that enhances both comfort and visibility. In this position, the operator can efficiently access the buccal and lingual surfaces of the posterior teeth while keeping a stable and comfortable stance. By using the 9-12 position, the operator can also work effectively on the upper and lower arches, ensuring thorough polishing on all necessary surfaces. The other clock positions, while possibly usable in certain contexts, do not offer the same level of ergonomics and access to the areas most commonly targeted during tooth polishing. This makes the 9-12 position the preferred and most effective choice for professionals performing coronal polishing.
