# Awareness of Medication-Related Osteonecrosis of the Jaws amongst Dental Professionals in Poland
## 5 Conclusions  
In our survey, dentists specializing in dental and maxillofacial surgery exhibited the highest degree of knowledge about MRONJ. The remaining groups did not differ in their level of knowledge between each other. The duration of work experience does not translate into greater knowledge about MRONJ. It is noteworthy that the dentists working in the private sector have less contact with patients suffering from MRONJ, which translates into a lower level of knowledge about this disease than the dentists working in both the public and private sector. It must be emphasized that the knowledge of the students was similar to that of practicing dentists. The quality of education received by the students of MUG on the topic of MRONJ is reasonably high. Providing students with adequate education about MRONJ could be major aspect of MRONJ prevention in the future. Considering the results of the study, it is advisable to further promote the knowledge about prophylaxis and dental preparation of patients for the implementation of antiresorptive treatment, e.g., in the form of generally accessible trainings, studies or webinars. It is encouraging that the majority of respondents declared a desire to know more about MRONJ which, in turn, could contribute to a decline of the occurrence of the disease in the future.
