What finger is used for fulcruming, and where should it be placed?

The correct response emphasizes the importance of utilizing the ring finger for fulcruming during coronal polishing. The ring finger effectively stabilizes the handpiece by being placed on a tooth in the same arch being polished. This positioning enhances control and stability, allowing for more precise movements and reducing the likelihood of causing discomfort or injury to the patient.

By using the ring finger as a fulcrum, dental professionals can achieve better leverage, ensuring that they can apply the appropriate amount of pressure without compromising the integrity of the surrounding tissues. This technique is essential for achieving optimal results while ensuring patient safety, making it a foundational skill in dental hygiene practices.
