Aim: Evidence‑based dentistry (EBD) is an approach to oral health that requires the
application and examination of relevant scientific data related to the patient’s oral health
and his priorities. The aim of this study was to assess knowledge, attitude, and practice of
dental students of Isfahan about EBD. Materials and Methods: In this descriptive study,
168 dental students in 3 final years of their education who engaged in clinical practice by
consensus sampling were recruited. For data collection, a validated questionnaire was used.
The questionnaire was consisted of demographic questions and some questions about
four issues: Knowledge of self‑assess (KSA), evidence‑based practice, actual knowledge
and attitude about EBD. Data were analyzed with t‑test, one‑way ANOVA, Chi‑square, and
linear regression with SPSS 16. Results: One hundred and thirty‑six students from 168
students were filled the questionnaire. The mean of KSA was 13 ± 4.3, mean of usage
of useful references in EBD was 16.9 ± 7.6. One‑third of students were studied their last
article in last 6 months before. The mean of actual knowledge and attitude was 7.4 ± 2.3
and 24 ± 3.8, respectively. The relation between 4 main issues was significant (P < 0.05).
Conclusion: By considering overall interest and positive attitude toward learning EBD in
dental students, it is highly recommended that practical educational courses about EBD
be planned by dental faculties.
