Which procedure is part of an oral prophylaxis?

An oral prophylaxis is a preventive dental procedure aimed at maintaining oral health by removing plaque, calculus (tartar), and debris from the teeth and gums. This process is typically performed by dental hygienists or dental assistants and is crucial for preventing gingivitis and periodontal disease.

The removal of calculus and debris is central to an oral prophylaxis, as it helps to reduce the buildup of harmful bacteria in the mouth. This service often involves scaling and polishing the teeth, which not only cleans the surfaces but also leaves the teeth smooth to help prevent future accumulation of plaque.

In contrast, root canal treatment, restoration of cavities, and radiographic examinations do not fall under the category of oral prophylaxis. Root canal procedures focus on addressing decayed or infected pulp tissue, while restorations involve repairing damaged teeth. Radiographic examinations are diagnostic tools used to evaluate the condition of the teeth and surrounding structures. Thus, while these other procedures are vital to overall dental care, they are not included as part of an oral prophylaxis, making the removal of calculus and debris the correct answer.
