Aim: The objective of our study is to conduct research on changes in the treatment plans to be applied by oral and maxillofacial surgeons, periodontists, endodontists, prosthetic dentists, and dentists on patients requiring endodontic treatment according to periapical radiography and cone-beam computed tomography. Materials and Methods: The eight cases in the study were obtained from the available registered patient archive. The case definitions created for the selected patients in our survey study were applied to 305 physicians via both imaging methods separately and by keeping minimum 4 weeks between the two stages. The physicians were requested to select the most appropriate one of the treatment plans determined separately for the 8 cases at both stages and the difficulty in decisionmaking at this stage. For statistical analysis, descriptive statistical criteria, independent samples t-test, one-way analysis of variance, the Likelihood Ratio, Mann-Whitney U and Kruskal-Wallis H tests were used. Results: Of the 305 physicians included in our study, 111 are dentists, 46 are oral and maxillofacial surgeons, 46 are periodontists, 49 are endodontists, and 53 are prosthetic dentists. It was found that there were differences in treatment plans among the specialty, endodontists generally planned the treatment more conservatively than other physicians at both stages, and their perceptions of the difficulty level at the stage of treatment planning were lower compared to other physicians. Conclusion: It was observed in our study that differences occurred especially in the treatment plans, which were made by physicians with CBCT images, for complicated cases, and the importance of the dental specialty status was understood in the decisions.
