Oral health is an integral part of general health, affecting individuals, the health system and society.
Oral diseases are some of the most prevalent chronic conditions and are preventable if evidence-based policies and practices are informed with quality and up-to-date data. Population Oral Health research is a major branch of dental research, producing the essential information used by the scientific community, policymakers and dental service providers, the profession, the industry, and the public to improve the oral health of communities at national, regional and global levels. To achieve this, evidence-based research, including national surveys and surveillance efforts, are required by policymakers and service providers.
About us
The Population Oral Health group was established at School of Dentistry, The University of Queensland in 2021. The group comprises of highly successful academics and researchers with multi-disciplinary expertise to conduct mixed methods population health research. Some of the main research themes of the group include:
- Population oral epidemiology
- Causal inference research
- Research in health inequality
- Policy development and research translations
- Health promotion
- Dental health services research
POHUQ research is typically funded by competitive grant bodies, both nationally and internationally.
Our vision

- This month saw us kick off the new state-wide Queensland Child Oral Health Study (QCOHS), investigating the oral health of Queensland children. Our first participating school is Shorncliffe State School. We received wonderful support from school staff, and an enthusiastic response from students and their parents. Our examination team commenced at the school on 18 November 2022 to check participating children’s teeth. Many thanks to the Shorncliffe State School community.
- In total, over 5,500 Queensland children will be invited to take part in QCOHS and free dental examinations as part of the study. QCOHS is conducted by Population Oral Health at UQ, in collaboration with the Clinical Excellence Queensland and the Department of Education.
