In a health access setting, which institution is NOT included?

In a health access setting, the focus is on institutions that aim to provide medical and dental care to vulnerable populations, particularly in underserved areas. A private dental practice, while it may offer important dental services, operates primarily as a for-profit establishment and does not specifically target public health outcomes or access issues in the same way as federally qualified health centers, nonprofit community health centers, or Head Start centers do.

Federally qualified health centers and nonprofit community health centers are both designed to provide comprehensive health services regardless of a patient's ability to pay, emphasizing their role in reducing health disparities. Head Start centers, although primarily focused on early childhood education, often play a crucial role in connecting families to healthcare services, including dental care, particularly for low-income families.

Therefore, the inclusion criterion for health access settings favors institutions and organizations that prioritize accessibility and community health over the profit motive, which distinguishes a private dental practice from others mentioned in the context.
