Which of the following is an example of a primary prevention strategy in social dentistry?

Community water fluoridation is an example of a primary prevention strategy in social dentistry because it aims to prevent dental caries (tooth decay) before they occur. By adding fluoride to public water supplies, communities can reduce the incidence of cavities across the population, promoting overall oral health without needing to treat individual cases after they arise. This public health measure is effective for both children and adults, contributing to a lower prevalence of dental issues in the community.

In contrast, routine dental cleanings are more about secondary prevention, as they help to prevent further issues in individuals who may already have some level of dental disease. Dental implants and orthodontic treatments fall under restorative and corrective procedures rather than preventive measures. Their primary focus is on addressing existing dental problems or malocclusions rather than preventing them in the first place.
