Material and methods
A survey was designed to examine the perceptions of orthodontists toward evidence-based practice in orthodontics. To minimize bias among participants, the term evidence-based practice was not used in the survey. Instead, the questions were phrased as inquiries regarding the use of scientific literature in orthodontics. Each participant was asked to respond to a set of demographic questions, followed by a set of questions pertaining to scientific literature in clinical orthodontics. Most survey
Results
The survey was sent to 8455 orthodontists, it was opened by 4771, and 1517 participated in the study. The response rate was 32%. The modal age group of the sample was 41 to 60 years, there were 79% men and 21% women, and the modal number of years in practice group was 16 to 20 years (Table I). Twenty-eight percent of the respondents were involved in teaching; 59% of the respondents had master’s degrees.
Discussion
The response rate in this study was 32%; this is lower than evidence-based surveys conducted in other fields.9, 10, 15, 16, 17 The studies in medicine attributed their high response rates to short, concise surveys, anonymity, the support of professional leaders, and professional membership.9, 15, 17 Because this was the first survey of its kind in orthodontics, it was designed to be comprehensive and therefore longer. This study also involved a much larger overall number of respondents (n =
Conclusions
Orthodontists expressed awareness and positive attitudes toward evidence-based practice. However, awareness of the Cochrane database was low, and understanding of evidence-based practice terminology was poor. Most respondents currently seek advice from colleagues when faced with clinical uncertainties, and expert advice was the most frequently selected reason for changing a practice philosophy. Conflicting and ambiguous literature, lack of clinical guidelines, and practical demands of work were
