An oral prophylaxis includes

An oral prophylaxis is a dental procedure that involves a thorough cleaning of the teeth and gums. This typically includes removing plaque, calculus (hardened plaque), and other debris from the teeth and gumline. This process helps to prevent gum disease and tooth decay. While whitening the teeth and applying fluoride are common dental procedures, they are not typically included in an oral prophylaxis. Filling cavities is also not part of an oral prophylaxis, as this procedure is used to restore teeth that have already been damaged by decay or other issues. Therefore, the best answer is B removal of calculus and debris.
