A Review of the Global Literature on Dental Therapists

OBJECTIVE: Access to adequate oral health care is deficient in many parts of the world. Many countries are now using dental therapists to increase access, particularly for children. To inform the discussion on dental therapists in the workforce, particularly in the United States, the W.K. Kellogg Foundation funded a review of the global literature to identify as many documents as possible related to the practice of dental therapists since the establishment of the School Dental Service in New Zealand in 1921. METHODS: Consultants in each of the countries considered to have a substantive literature on dental therapists were asked to participate in the research; seventeen in total. In addition to identifying and reviewing published articles, a focus of the research was on identifying \u27gray\u27 documents. Standard databases were searched for key words associated with dental therapists. In addition, searches were conducted of the governmental and dental association websites of all countries known to have dental therapists in their oral health workforce. RESULTS: Fifty-four countries, both developing and developed, were identified where dental therapists are members of the workforce. Eleven hundred documents were identified from 26 of these countries, with over 2/3 of them cited in the published monograph. Reliable evidence from the related literature and verbal communication confirmed the utilization of dental therapists in an additional 28 countries. Thirty-three of the countries were members of the Commonwealth of Nations, suggesting a mechanism of spread from New Zealand. Variable lengths of training/education existed for dental therapists with the tradition being 2 years postsecondary. In a few countries, the training of therapists and hygienists is now being combined in a three academic year program. Historically, dental therapists have been employed by government agencies caring for children, typically in school-based programs. Initiatives in some countries allow limited care for adults by dental therapists with additional training. CONCLUSIONS: The evidence indicates that dental therapists provide effective, quality, and safe care for children in an economical manner and are generally accepted both by the public and where their use is established, by the dental profession

"Then you get a teacher" - Guidelines for excellence in teaching

Background: Current literature calls for the explicit teaching to health-science educators of the skills, knowledge and dispositions that are required for successful teaching in higher education. Aims: This paper draws on evidence from an Oral Hygiene department at a South African university in order to illustrate these teaching-competency needs. Insights from the evidence are synthesised with current literature regarding best teaching practice, in support of an appropriate framework for the development of teaching competencies to health-science educators. Description: A qualitative approach, using a case study, was adopted. The cohort comprised fifteen students in the first-year Oral Hygiene cohort class and the ten educators who taught their programme. Data was collected through semistructured interviews and open-ended questionnaires. The topics that emerged from the combined analysis of the interviews and the questionnaires were organised into a grid so that common themes could be identified. Current literature regarding teaching and learning was used as a framework for interpreting the empirical evidence, from which three categories emerged. The first category included suggestions from students regarding what to do to teach better. A review of the literature indicates that these competencies can be effectively learnt from self-help guides. The second category included requests for skills development. Literature review suggests that these might effectively be learnt from single-event workshops facilitated by more able peers. Responses in the final category highlighted the need for an underpinning theory of teaching and learning, and signalled the need for a more theoretically grounded and detailed approach to teacher development. Conclusion: The framework developed from the empirical study and current literature makes it possible for individual clinical teachers, and staff developers, to construct teaching-competency development plans that are pertinent to individual teachers’ needs, relevant and practical, educationally sound, and cost-effective in terms of time and effort
