What is the function of a fulcrum during the polishing process?

The function of a fulcrum during the polishing process is to provide support and stability. When dental assistants perform coronal polishing, it is crucial to maintain control over the handpiece and polishing cup to achieve effective results while minimizing the risk of damage to the teeth and surrounding soft tissues. Using a fulcrum allows the assistant to stabilize their hand, which ensures that movements are precise and deliberate. This stability is especially important in reaching different areas of the tooth surface without straining the wrist or hand.

By anchoring the hand with a fulcrum, the dental assistant can apply consistent and effective pressure during the polishing process. This leads to better control over the polishing instrument, which can help achieve a smoother and shinier tooth surface, making the procedure more efficient and safer for the patient.
