The questionnaire was validated and its reliability was confirmed by retesting 10 samples after 2 weeks with a cronbach alpha of 0.9. The online questionnaire was sent to 4 dental schools in the city of Tehran and was fill out by 170 dental students.

RESULTS

The mean knowledge score for all 170 participants was 16.23 out of 32 (50.72%) with the maximum score of 24 (75.0%) and the minimum score of 1 (3.1%). There was a significant relationship between the gender of participants and their knowledge score (p = 0.032) in the way that male students had significantly higher score than females. Students with more advanced educational level achieved higher knowledge scores. (p = 0.038) However, there were no significant correlation between other variables and the students' knowledge score. (p > 0.05).

CONCLUSION

Dental students had acceptable knowledge about the general protocols against corona virus in terms of hand hygiene, wearing face masks, surface sanitization and diagnostic symptoms of a patient susceptible to be infected by corona virus. However, mostly they were not aware of the details of the guideline's items which makes it crucial to add related content in the dental students' educational curriculum.
