For the ADHS, 11,380 individuals were interviewed and 6,469 dentate adults were examined, making it the largest adult epidemiological survey ever in the United Kingdom
The survey was commissioned by the NHS Information Centre for Health and Social Care, the Welsh Assembly Health Department and the Department of Health, Social Services and Public Safety in Northern Ireland. It was managed principally by the Office for National Statistics (ONS). (Scotland decided not to participate.)
The 2009 survey consisted of a questionnaire interview for adults aged over 16 years at all sampled households, and an oral examination of the mouth and teeth of all those adults who had at least one natural tooth. Statistics were collected and recorded by community dental officers (often assisted by dental nurses) who examined sections of the population in their areas and charted results.
These statistics were sent to the ONS where they were analysed, collated and published in form 12, 3]. Reports can then be used by area authorities considering, for example, whether to fluoridate their water supply or implement procedures to control drinks sold in school tuck shops
