Define the term "prophylaxis" in dental care.

Prophylaxis in dental care specifically refers to preventive treatments aimed at maintaining oral health and preventing disease. This typically includes procedures like professional cleanings, where plaque, tartar, and stains are removed from the teeth, as well as patient education on oral hygiene practices. The focus of prophylaxis is to prevent conditions such as cavities and periodontal disease, which can arise from poor oral hygiene.

While options related to repairing decay, surgical procedures, or teeth whitening have important roles in dental care, they do not embody the principle of prevention that prophylaxis represents. Repairing decay involves addressing existing issues rather than preventing them, surgical procedures might be necessary interventions rather than preventive measures, and teeth whitening focuses on aesthetics rather than on overall oral health maintenance. Thus, the definition of prophylaxis encompasses essential preventive measures that promote long-term dental health.
