Objective: To evaluate the knowledge and attitude of the students of Kerman dental school (Iran) about ethics in dental research. Material and Methods: This cross-section study was conducted on 307 dental students selected through the census sampling method. Data were collected by a researcher-made questionnaire consisting of 12 items about knowledge and 17 items about attitude toward research ethics. Data analyzed in SPSS software using t-test and linear regression test. P-values of less than 0.05 were considered statistically significant. Results: Of the respondents, 33.9% were male and 66.1% were female, and 44% had good knowledge and 20.8% had a positive attitude about research ethics. A significant correlation was found between knowledge and attitude. A significant correlation was also observed between knowledge and participation in research workshops. Knowledge and attitude showed no significant correlation with gender or year of admission. Conclusion: Participants had appropriate knowledge and attitude about research ethics. There is some room for improvement in research ethics education concerning experimental works and retrospective studies on biologic samples. Holding research workshops with an introduction to ethical codes of research is recommended.
