The Australian Research Centre for Population Oral Health (ARCPOH) will be conducting the 2021 National Dental Telephone Interview Survey (NDTIS 2021) in collaboration with the Commonwealth Department of Health.

Approximately 8,000 people will be interviewed by telephone or via online survey in order to gather information on socioeconomic conditions, dental service use, oral health behaviours, and other determinants of oral health.

The main aims of the study are to assess population oral health outcomes and their determinants and to monitor them over time in order to inform policy makers, professional bodies and the public.

NDTIS 2021 will be a cross‐sectional survey of a representative sample of the Australian population aged 5 years and over, across each State and Territory.

The survey is expected to commence mid-April 2021.
