Quizplus · Accepted Answer

Coronary polish should not be performed on patients with orthodontic appliances as the polishing paste can damage the appliances. Minor oral irritations such as canker sores or cuts in the mouth can be further irritated by coronal polish. Patients with hypersensitive teeth may experience discomfort during or after the procedure. If a patient is hard to control, it is best to reconsider performing any procedure that requires cooperation. Therefore, options A and D are incorrect, while option B is too limited. Option C is the best choice as it includes all the contradictions or modifications for a coronal polish.
