What precautions should be taken before performing coronal polishing?

Before performing coronal polishing, it is essential to review the patient's medical history and secure informed consent to ensure the safety and appropriateness of the procedure for the individual patient. Understanding the patient's health conditions, allergies, and medications can help prevent any potential complications or adverse reactions during the polishing process. Informed consent is crucial as it ensures that the patient understands what the procedure involves, its purpose, and any associated risks, allowing them to make an educated decision about their care.

In contrast, the other options do not directly address the requirements of patient safety and procedural appropriateness. Using a fluoride mouthwash prior to the procedure might promote oral health but does not substitute for the comprehensive evaluation of the patient's medical history. Skipping the patient evaluation steps is not acceptable as it disregards important safety protocols that protect the patient. Applying dental sealants is a separate procedure that has no bearing on the safety or necessity of coronal polishing. Each of these factors emphasizes the importance of thorough pre-procedural protocols, with the review of medical history and informed consent being foundational to patient care.
