Increasing use of cone beam computed tomography (CBCT) for dentomaxillofacial diagnosis raises concerns about radiation dose which is known to be higher compared to conventional dental imaging methods. This retrospective study investigated the CBCT referrals in a Turkish paediatric subpopulation in terms of referring department, field of view (FOV),and findings.
A total of 8,880 CBCT images were reviewed retrospectively and images of paediatric patients (?14 years old) were selected. In paediatric patients; data related to patient age and gender, referring department, FOV, region of interest for localised applications, and reason for CBCT referral were recorded. FOVs of CBCT scans were classified as face, jaws (maxilla and mandible), maxilla, mandible, and tooth. CBCT indications were categorised based upon an adaptation of the European DIMITRA (dentomaxillofacial paediatric imaging: an investigation towards low-dose radiation induced risks) multicenter and multidisciplinary project recommendations as impacted teeth, trauma, orofacial clefts, dental anomalies, bone pathology, syndromes, and other. Patients undergoing consecutive CBCT examinations for follow-up were also recorded. In order to record the incidental findings noticed in the CBCT evaluation, the radiological report prepared by the radiologist was used. The results were analysed statistically with a significance level set at p<0.05.
Four hundred forty-nine of the 8880 CBCT scans were taken from paediatric patients under the age of 14, representing approximately 5% of all scans. Most of the referrals were from Department of Paediatric Dentistry (36.3%), followed by Department of Orthodontics (25.6%). The most frequently imaged region was the maxilla (33.4%), followed by the face (20.5%). The most common region of interest for localised applications was the maxillary canine/incisor region (85.55%). The most common indication was impacted teeth (41.4%) followed by bone pathology (31%) and dental anomalies (29.6%); 11.6% of the patients underwent follow-up CBCT examinations especially for orofacial clefts and syndromes.
This retrospective study investigating CBCT indications in a Turkish paediatric subpopulation and comparing existing applications with DIMITRA project recommendations can guide dental professionals in referring paediatric patients for CBCT.
随着锥形束 CT（CBCT）在口腔颌面诊断中的应用日益增多，人们对其辐射剂量的担忧与日俱增，与传统牙科成像方法相比，CBCT 的辐射剂量更高。本回顾性研究调查了土耳其儿科人群的 CBCT 转诊情况，包括转诊科室、视野（FOV）和发现。
共回顾性分析了 8880 例 CBCT 图像，选择了儿科患者（<14 岁）的图像。在儿科患者中，记录了与患者年龄和性别、转诊科室、FOV、局部应用的感兴趣区域以及 CBCT 转诊原因相关的数据。CBCT 扫描的 FOV 分为面部、颌骨（上颌和下颌）、上颌、下颌和牙齿。根据欧洲 DIMITRA（口腔颌面儿科成像：对低剂量辐射诱导风险的调查）多中心和多学科项目建议的改编，将 CBCT 适应证分为受影响的牙齿、创伤、口面裂、牙齿异常、骨病变、综合征和其他。还记录了接受连续 CBCT 检查以进行随访的患者。为了记录 CBCT 评估中发现的偶然发现，使用了放射科医生准备的放射报告。使用统计学方法分析结果，显著性水平设为 p<0.05。
在 8880 例 CBCT 扫描中，有 449 例来自 14 岁以下的儿科患者，占所有扫描的 5%左右。大多数转诊来自儿科牙科系（36.3%），其次是正畸科（25.6%）。最常成像的区域是上颌（33.4%），其次是面部（20.5%）。最常用的局部应用感兴趣区域是上颌尖牙/切牙区域（85.55%）。最常见的适应证是受影响的牙齿（41.4%），其次是骨病变（31%）和牙齿异常（29.6%）；11.6%的患者接受了后续 CBCT 检查，特别是针对口面裂和综合征。
本回顾性研究调查了土耳其儿科人群的 CBCT 适应证，并将现有应用与 DIMITRA 项目建议进行了比较，可为牙科专业人员为儿科患者转诊 CBCT 提供指导。
