Research design

Participants were selected using a random sampling strategy, ensuring adequate representation from rural and urban settings, as well as of individuals living independently in the community and in long-term care facilities.

The study measured four main components:

  • impact of oral health on quality of life
  • utilization of oral health care services
  • clinical oral health status
  • oral health treatment needs

The first two components were measured through a questionnaire and the last two were measured through a clinical examination held at selected community sites across the province.
