Educating dental practitioners is a major component in obtaining evidence-based approach to oral health care, but there is no evidence about knowledge and attitude of dental faculty members towards evidence-based dentistry (EBD) in Iran.

Materials and methods

A cross-sectional study was conducted using self-administered questionnaires on dental school faculties in Iran to assess their knowledge and attitude towards basic principles and methods of EBD. A total of eight dental schools were randomly selected of 17 public and two existing private schools. Validated questionnaire with an appropriate reliability (Cronbach's alpha 0.67 – 0.87) was conducted on (n = 505) available dental instructors. The covered dimensions were perceived knowledge on critical appraisal, actual knowledge of EBD concepts, evidence-accessing methods and attitudes about EBD. Correlations were assessed between background characteristics and four main parts of the questionnaire, and multiple linear regression analysis was also used.


A total of 377 of 505 dental instructors returned completed questionnaires (response rate 74.65%). The mean perceived knowledge score was 15.32 ± 4.69 on a range of 6–36, and mean actual knowledge was 7.98 ± 2.0 on a range of 0–11 for all respondents with an overall positive attitude towards EBD.


This study suggests that the level of actual knowledge of dental faculties about basic principles of EBD was moderate in Iran. However, faculties' overall interest and positive attitude towards learning EBD is encouraging. Therefore, it is highly recommended that degree/certificate continuing educational programmes be planned by the organising committees.
