Dental public health research in action: population and community-based research.

Population-based epidemiologic studies are at the heart of dental public health research, as well as many other types of clinical and translational studies that aim to benefit dental practice, influence oral health policies, and improve the oral health and health of the public. This article gives examples of dental public health research in action, including many ongoing or recently completed studies conducted in California.
