International policy case study

Research title: Closing the oral health gap by influencing national and international policy
Faculty: UCL Population Health Sciences
Activity: Research
Policy type: International public health
Country/Region: Europe
Policy partner: UK Government (Home Departments)


Oral diseases such as tooth decay, gum disease and mouth cancers affect an estimated 3.5bn people globally, disproportionately affecting poorer and marginalised groups. The UCL Dental Public Health Group (DPHG) has led research showing this oral health gap shares the same underlying drivers as inequalities in other noncommunicable diseases such as cancer and heart disease. Their findings have influenced policy to reduce these oral health inequalities in the UK and globally.
