When establishing a fulcrum, what precaution must be taken?

Establishing a fulcrum is essential in maintaining stability and control during coronal polishing procedures. It helps the dental professional achieve precision while minimizing hand strain and ensuring patient safety. Wearing gloves is crucial for infection control, creating a barrier between the clinician and potential contaminants; this is a standard practice in all dental procedures to maintain hygiene and protect both the patient and the practitioner.

Using only a handpiece doesn't address the importance of ergonomics and stability that a fulcrum provides. A steady hand is critical for effective polishing, as it leads to better control and reduces the risk of injury to the patient. Therefore, considering all of these critical precautions collectively ensures a safe and effective procedure. Each aspect contributes to achieving optimal results while prioritizing safety and clinical effectiveness in a coronal polishing context.
