Introduction: Head and neck cancer encompasses cancers that develop in the oral cavity, salivary glands, paranasal sinuses, nasal cavity, larynx, pharynx, and upper neck nodules. The goal of treating these cancers is to eliminate the tumor while preserving the patient's quality of life and preventing potential complications. Radiotherapy, one of the treatment methods, can lead to undesirable changes in surrounding tissues. This study aims to investigate the awareness of dentists regarding osteoradionecrosis, a significant side effect of radiotherapy in patients with head and neck cancer. Materials and Methods: In this survey study, dentists from 12 different regions in NUTS-1, as determined by TURKSTAT were contacted via digital media and their participation in the study was ensured. Participants were asked 16 questions related to osteoradionecrosis, prepared through a literature review. For the statistical analysis of the data collected from the questionnaires, frequency analysis, and chi-square tests were performed with the help of the SPSS 23 package program. A p-value<0.05 indicated statistical significance. Results: A total of 634 participants, including 278 (44%) intern dentists, 149 (24%) general practitioner dentists, 128 (20%) doctoral-specialty students, and 79 (12%) specialist dentists, were included in the study. The analysis of the collected data from the study showed that doctoral specialty students and specialist dentists have more knowledge about the risk factors and diagnosis of osteoradionecrosis (p=0.000<0.050). Conclusion: To enhance awareness of osteoradionecrosis among general and trainee dentists, it would be beneficial to increase educational content within undergraduate programs and to support this with continuous education activities.
