INTRODUCTION: Evidence‑based dentistry (EBD) is an approach to oral healthcare by combiningthe best scientific evidence and clinical diagnostics, clinical expertise of the dentist, and the patient’streatment needs and preferences. The aim of the present study is to evaluate the effectiveness ofan education program on EBD offered in a community‑dentistry course in improving knowledge andattitudes of students in this regard.STUDY METHODS: By a quasi‑experimental study design, 64 senior dental students of IslamicAzad University of Khorasgan recruited in a controlled trial. All of the students were randomized asintervention (32) and control (32) groups. A course‑based educational program on EBD was randomlyassigned to one group. Actual knowledge, self‑assessed knowledge, and attitudes, before and aftereducation, were measured in both groups. A questionnaire consisted of 40 items developed by theresearcher was used after confirming its validity and reliability. The difference between mean scoresat two timelines were measured and compared in three fields by paired t‑test and independent t‑testanalysis via SPSS version 20 software.RESULTS: While the mean scores of actual and self‑assessed knowledge and attitude were notsignificantly different between two groups at the beginning of the program (P > 0.05), the meanscores of all fields in the intervention group were significantly more than those of the control groupafter education (P < 0.001). The effect size of intervention was 86%, 62%, and 57% in three fields,respectively. There was not a significant difference between mean scores of three fields in the controlgroup, after the intervention.CONCLUSION: Due to the poor knowledge and attitudes of students and improved knowledge andattitudes of the intervention group after education, the education program seems to be effective.Durability of educational impact and evaluating evidence‑based performance can be studied in thefuture.
