# Awareness of Medication-Related Osteonecrosis of the Jaws amongst Dental Professionals in Poland
## 3 Results
However, only below 60% of the dentists in groups G2 and G3 and students knew the importance of the way of BP administration for MRONJ occurrence. Dental specialists in oral and maxillofacial surgery showed better comprehensive knowledge of risk factors, but insufficient for steroid therapy and tobacco use. It is surprising that only 37.4% of students pointed to alcohol as an incorrect answer, which is the lowest result among all examined groups. Detailed results are shown in Table 4.

Table 2: Answers to the question concerning the diseases treated with bisphosphonates. Only a little more than half of surveyed participants (55.2%) declare that they know the guidelines of MRONJ treatment (Table 5). In the results there is a visible disproportion in answers to this question between groups G1 and G2.
