Knowledge of Iranian Dentists about Osteonecrosis of the Jaw due to the Use of Bisphosphonate Drugs

Abstract

Objective: To evaluate the knowledge of Iranian dentists regarding bisphosphonate-related osteonecrosis of the jaw (BRONJ) etiology, risk assessment, and clinical management, aiming to identify gaps in knowledge and inform targeted educational interventions. Material and Methods: This analytical cross-sectional study was performed on 2000 dentists whose list was obtained from the Medical Council Organization. A questionnaire, whose validity and reliability were ensured, containing demographic questions (age, sex, etc.), general questions, and questions about bisphosphonate use, was provided to individuals. The data were analyzed using the t-test, Mann-Whitney test, and Chi-Square test. The level of significance was p < 0.05. Results: Of the participants, 56 were male, and the mean age was 32.5 +/- 5.6 and and 51.5 had less than 5 years of professional experience. Approximately 27.5 of dentists were familiar with the term MRONJ. The mean knowledge score was 10.4 +/- 2.1, indicating poor dentists' knowledge. There was no significant difference between knowledge score, age, sex, working hours, and work experience. Conclusion: Dentists' knowledge of BRONJ is inadequate. A patient with bisphosphonate-related osteonecrosis can be a significant challenge for the dentist, and sufficient understanding of the signs, treatments, and management of these patients is necessary for any dentist.
