What is the first step in managing unexpected reactions during coronal polishing?

The first step in managing unexpected reactions during coronal polishing is to cease the procedure immediately. This action ensures the safety of the patient and allows for a thorough assessment of the situation. Stopping the procedure prevents any further discomfort or injury while enabling the dental professional to evaluate the reactions more carefully and determine the appropriate next steps.

Taking immediate action to halt the polishing process is crucial in maintaining patient welfare and responding effectively to any adverse events. It allows the practitioner to address any immediate concerns or complications. Once the procedure is stopped, the dental team can then decide if further intervention is necessary, whether that involves notifying other staff, applying treatments, or providing additional support to the patient.

In contrast, continuing the procedure or attempting to increase the speed of the polishing tool could exacerbate the situation, potentially making the reaction worse. Similarly, applying a numbing agent may not address the underlying cause of the unexpected reaction and could delay necessary assessment. Therefore, ceasing the procedure is the most prudent and responsible initial response.
