The Dunedin Multidisciplinary Health and Development Study: Oral health findings and their implications.

Longitudinal research is needed to better understand the natural history of oral conditions and long-term health and social outcomes. Oral health data has been collected periodically in the Dunedin Multidisciplinary Health and Development Study for over 40 years. To date, 70+ peer-review articles on the Study's oral health-related findings have been published, providing insight into the natural history of oral conditions, risk factors, impacts on quality of life, and disparities in oral health. Some of these report new findings, while others build upon the existing body of evidence. This paper provides an overview of these findings and reflects on their public health implications and policy utility in New Zealand.
