Which of the following is an example of a social determinant of health?

• A. Income level
• B. Tooth color
• C. Brushing technique
• D. Fluoride toothpaste brand

Answer: (A)

Social determinants of health are the conditions in which people are born, grow, work, and age that are shaped by how money, power, and resources are distributed. Income level best fits as a social determinant because it reflects overall socioeconomic status and directly influences access to dental care, affordability of preventive services, and the ability to live in environments that support good oral health. This means people with higher income often have easier access to routine checkups, sealants, fluoride treatments, and timely care, which can prevent problems before they become serious.

In contrast, tooth color is more of an aesthetic outcome, brushing technique is a personal habit, and fluoride toothpaste brand is a consumer choice. These relate to individual behavior or product preference rather than broader social conditions that shape health outcomes.
