Coronal Polishing for Dental Assistants Certificate Practice Test 2025 - Free Practice Questions and Study Guide for Dental Assistants Certification

Question: 1 / 400

How is the polishing cup positioned over the tooth during the procedure?

Directly flat on the tooth

At a slight angle to avoid splatter

Positioning the polishing cup at a slight angle over the tooth during the coronal polishing procedure is crucial to achieving effective cleaning while minimizing any mess. This slight angle allows for better access to the various contours of the tooth's surface, ensuring that all areas, including grooves and interproximal spaces, can be adequately polished. Additionally, angling the cup helps to control splatter of the polishing paste and saliva, which enhances the cleanliness and comfort of the procedure for both the patient and the dental assistant.

Other options might suggest different positions, such as being flat against the tooth or at sharp angles, which could compromise the effectiveness of the polishing and lead to discomfort or potential injury to the gums. Proper technique, including angling the polishing cup, is a key aspect of safe and effective coronal polishing.
