Oral health survey of year 6 data tables


This survey took place in mainstream, state-funded schools in England in the academic year 2022 to 2023. The population for the survey was schoolchildren in year 6. This was the first time this population group has been surveyed. The survey was carried out as part of the Office for Health Improvement and Disparities’ National Dental Epidemiology Programme (NDEP).

The aim of the survey was to measure the prevalence and severity of tooth decay in permanent teeth among children in year 6 within each lower tier local authority. This was to provide information to local authorities, the NHS and other partners on the oral health of this cohort of children in their local areas and to highlight any inequalities. The national protocol for the survey was published in September 2022.
