Educational Models for the Re-Establishment of Dental Therapy Education in Canada.

Abstract

With the closure of the Canadian dental therapy program in Saskatchewan in 2011 and the increasing need for oral health providers, there have been growing discussions at the national and provincial levels regarding the re-establishment of a provider with dental therapy abilities. The aims of this study were to define models for dental therapy education in Canada and explore how dental therapy abilities could best be integrated into Canadian post-secondary education. In 2017, purposeful sampling was used to invite key informants to participate in a semi-structured interview. Participants were individuals from government, education, and regulation and those working with underserved populations in Canada and internationally. A 75% response rate (n=53) was achieved. Thematic analysis was employed for coding of data and generation of themes. Respondents highlighted the need to include minimally invasive restorative services in the current scope of dental hygiene practice across all Canadian jurisdictions and to build dental therapy abilities with or upon accredited dental hygiene curricula. The models supported by respondents were a fourth-year option built on three-year diploma education, a one-year postgraduate diploma based on a baccalaureate degree and a current dental hygiene registration, and a three-year dental therapy diploma incorporating core courses in accredited dental hygiene diploma education. While the respondents' views were divergent, the educational model that received the most support involved a two- to three-term addition to current three-year dental hygiene diploma education. In contrast to international trends, the respondents valued learner flexibility to exit with a diploma dental hygiene credential, thus making the dental therapy scope optional. These educational models provide a starting point for further analysis and exploration.
