Fluoride varnish is particularly effective for which group of people?

Teenagers with braces
Older adults with dry mouth
Both A and B
Children who consume high sugar diets

The correct answer is: Both A and B

Fluoride varnish is particularly effective for both teenagers with braces and older adults with dry mouth due to the specific dental needs of these groups. In teenagers with braces, the presence of brackets and wires creates places where plaque can accumulate more easily, leading to an increased risk of cavities. The fluoride in the varnish helps to remineralize tooth enamel and provides a protective barrier against decay, making it a beneficial treatment option. For older adults with dry mouth, a condition often resulting from medications or health issues, the reduced saliva flow can make them more susceptible to cavities. Saliva is essential for neutralizing acids in the mouth and helping to remineralize teeth. Therefore, applying fluoride varnish can offer extra protection by enhancing enamel resistance to decay and compensating for the lack of natural protective factors that saliva would typically provide. Understanding the specific needs of these populations emphasizes the importance of addressing their unique oral health challenges, making fluoride varnish an appropriate preventive measure for both groups.
