摘要：Introduction: Periradicular surgery is an appropriate treatment method for dental periradicular impairments. The present study was carried out to analyze the knowledge of general dentists and dental specialists about periradicular surgery.Methods: This descriptive cross-sectional study was conducted on 93 general dentists and 7 dental specialists (Endodontists and Oral and Maxillofacial Surgeons) in Kermanshah. Data were collected by a standard questionnaire including demographic information and technical questions about the principals of periradicular surgery. Data were analyzed by SPSS (version 17) using t-test and Chi-square.Results: The knowledge of the specialists with the mean of 7.4 for correct responses was considered good and for general dentists, the mean of 5.1 for correct responses was considered average. There was a significant correlation between the educational status of the participants (specialists and general dentists) and their knowledge (P<0.001). Participation in retraining courses did not have any significant effect on the knowledge of specialists and general dentists on the principles of periradicular surgery (P<0.05). However, there was a significant difference between the work experience of the participants and their knowledge on periradicular surgery, so that by increasing the work experience, the knowledge of general dentists and specialists decreased (P<0.001).Conclusion: The knowledge of general dentists in Kermanshah about the principles of periradicular surgery was at average level. Endodontists and Oral and Maxillofacial Surgeons are recommended to carry out periradicular surgery as a typical part of clinical therapy.
