What should be monitored to prevent instrument failure during coronal polishing?

Monitoring the operation of the dental handpiece is crucial during coronal polishing because it directly affects the effectiveness and safety of the polishing procedure. A malfunctioning handpiece can lead to inadequate polishing, discomfort for the patient, or even injury if the device overheats or fails. Ensuring that the handpiece is functioning correctly allows for a smooth operation, creating a safe environment for both the dental assistant and the patient. This includes checking for proper speed and function, as these factors can contribute to instrument wear or damage if not properly managed. Regular assessments of the handpiece can prevent failures that may interrupt the polishing process or compromise the quality of care provided.
