To investigate the utilization of cone beam computed tomography (CBCT) in paediatric dentistry, focusing on the indications, referring departments, age distribution, oral regions examined, and fields of view (FOV) at Alexandria and Cairo universities.
This retrospective observational study reviewed records from 2018 to 2024 of patients under 19 years who underwent CBCT scans in the radiology departments. Data were analysed by sex (6-12 years and 13-<19 years), imaging area (anterior/posterior, mandible/maxilla), and indications following the 2011 SEDENTEXCT guidelines: dental anomalies, impacted teeth, endodontics, bone pathosis, orthodontics, and others.
Out of 988 patient records with CBCT scans, 260 paediatric cases were analysed. Referrals mainly came from the oral and maxillofacial surgery department (50%) and the paediatric dentistry department (40%). The primary reasons for CBCT scans included impacted teeth (40%), endodontic treatments (19.6%), and orthodontic assessments (15.8%). Significant usage patterns were noted across age groups, with 53.1% of patients aged 6-12 years and 46.9% aged 13-18 years. A diverse range of oral regions was examined, including the anterior mandible (30%), posterior mandible (25%), anterior maxilla (20%), and posterior maxilla (25%).
The findings reveal that CBCT is primarily used for assessing impacted teeth, endodontic treatments, and orthodontic needs in children and adolescents. Patients aged 6-<13 years were more often referred for endodontic issues, while those aged 13-<19 needed imaging for impactions and orthodontics. Differences in FOV among centres indicate varied clinical practices.
The study underscores the indications of CBCT in paediatric dentistry and the diverse clinical practices at both universities and highlights the need for tailored imaging protocols.
调查锥形束计算机断层扫描（CBCT）在儿童牙科中的应用情况，重点关注亚历山大大学和开罗大学的适应症、转诊科室、年龄分布、检查的口腔区域以及视野（FOV）。
这项回顾性观察研究回顾了2018年至2024年在放射科接受CBCT扫描的19岁以下患者的记录。数据按性别（6至12岁和13至<19岁）、成像区域（前部/后部、下颌骨/上颌骨）以及遵循2011年SEDENTEXCT指南的适应症进行分析：牙齿异常、阻生牙、牙髓病、骨病变、正畸以及其他。
在988份有CBCT扫描的患者记录中，分析了260例儿科病例。转诊主要来自口腔颌面外科（50%）和儿童牙科（40%）。CBCT扫描的主要原因包括阻生牙（40%）、牙髓治疗（19.6%）和正畸评估（15.8%）。各年龄组均有显著的使用模式，6至12岁患者占53.1%，13至18岁患者占46.9%。检查了多种口腔区域，包括下颌前部（30%）、下颌后部（25%）、上颌前部（20%）和上颌后部（25%）。
研究结果表明，CBCT主要用于评估儿童和青少年的阻生牙、牙髓治疗和正畸需求。6至<13岁的患者更多因牙髓问题被转诊，而13至<19岁的患者需要进行阻生牙和正畸成像。各中心视野的差异表明临床实践存在差异。
该研究强调了CBCT在儿童牙科中的适应症以及两所大学不同的临床实践，并突出了制定个性化成像方案的必要性。
