Coronal Polish Certification Practice Test

Question: 1 / 400

What instrument is primarily used for coronal polishing?

A high-speed handpiece

A rubber cup attached to a low-speed contra-angle handpiece

The instrument primarily used for coronal polishing is a rubber cup attached to a low-speed contra-angle handpiece. This combination is specifically designed for the purpose of polishing the surfaces of teeth, particularly the crowns. The rubber cup is effective for holding polishing paste, which helps to remove plaque, stains, and surface debris from the enamel without damaging it. The low-speed handpiece allows for better control and gentler movements, minimizing the risk of overheating the tooth or causing discomfort to the patient.

In contrast, a high-speed handpiece is typically used for cutting or drilling tasks rather than polishing, while a scalpel is meant for surgical procedures and tissue manipulation, and an ultrasonic scaler is used for scaling and removing calculus. Thus, the function and design of the rubber cup and low-speed handpiece make them the optimal choice for coronal polishing in dental hygiene.
