Coronal Polish Certification Practice Test

The correct approach for avoiding injury to the gingival tissue from the rubber cup involves moving the cup away from the gingival tissue and starting at the cervical area, then progressing to the occlusal or incisal surface. This technique minimizes the risk of the rubber cup coming into direct contact with the delicate gingival tissue, which can be easily irritated or damaged.

Positioning the rubber cup starting at the cervical line allows for better control and reduces the chances of applying too much pressure near the gums. By ensuring the cup operates further away from the gingival margin, clinicians can effectively polish the teeth while protecting sensitive tissues, preventing potential trauma that could lead to inflammation or recession.

While utilizing less pressure, an electric polisher, or a softer rubber cup can contribute to safer polishing practices, the emphasized technique of controlling the starting point and direction of the polishing enhances overall safety during coronal polishing and focuses specifically on protecting the gingival area.
