Background and objectives: This study aimed to assess the knowledge level of Yazd dental students about bisphosphonate-related osteonecrosis of the jaw (MRONJ). Materials and methods: This cross-sectional study was conducted on 113 fourth- to sixth-year dental students of School of Dentistry, Yazd Shahid Sadoughi University of Medical Sciences. A questionnaire was used to collect information regarding age, gender, academic year, grade point average (GPA), and history of encountering a case of MRONJ. The questionnaire had 13 multiple-choice questions regarding the knowledge level of students about the definition, classification, frequency of use, side effects, risk factors, and indications of bisphosphonates and treatment of MRONJ. Data were analyzed by t-test and Pearson’s correlation test (alpha = 0.05). Results: A total of 69 (61.1%) female and 44 (38.9%) male dental students participated in this study. The mean knowledge score of students about MRONJ was 14.42 ± 3.84 out of 17. No significant difference was found in the mean knowledge score of male and female students (P = 0.518). Knowledge score of students had significant inverse correlations with their age (r = -0.306, P = 0.001) and academic year (r = -0.184, P = 0.050) and a significant direct correlation with their GPA (r = 0.330, P = 0.000). Conclusion: The present results revealed good knowledge level of Iranian dental students regarding MRONJ. Knowledge level of students had significant inverse correlations with their age and academic year, and a significant direct correlation with their GPA.
