Abstract:

Objective: The objective of this study is to retrospectively examine the reasons of cone-beam computed tomography (CBCT) request and the distribution of these requests according to age, gender, departments and requested area in a group of patients. Methods: CBCT request forms obtained from the archive records were evaluated retrospectively. Age, gender, requesting departments, request reasons and requested areas were recorded. Request reasons were classified as intraosseos lesion, orthodontics, endodontics, impacted tooth, dental anomally, soft tissue calcification, preoperatif, trauma, implant surgery, evaluation of temporomandibular joint bone structure, and other causes. Requesting departments were classifield as Department of Oral and Maxillofacial Radiology, Department of Oral and Maxillofacial Surgery, Department of Orthodontics, Department of Endodontics and others. Requested areas were classified as maxilla, mandible, maxillofacial region and single tooth area. The data were analyzed by descriptive statistics methods with SPSS. Results: 679 CBCT request form included to the study and the mean age was 37.44± 17.39 of patients. The most common request reason was assesment of intraosses lesion (29.6%), the most CBCT requesting department was Department of Oral and Maxillofacial Radiology ( 51.4%) and the most requested area was maxillofacial region ( 52.9%). Conclusion: The results of the study showed that most of the CBCT images were requested for assesment of intraosseos lesion. Evaluating the request reasons of CBCT by physicians and determining the usage areas of CBCT can be beneficial in terms of improving the technique.
