Cone beam computed tomography can be used in pediatric population when a tridimensional analysis of dental and maxillofacial bone structures is required. Even though CBCT is considered a low dose radiological examination, ionizing radiation is a known human carcinogenic factor. Furthermore, biological effects are more important in young patients because of their higher radiosensitivity. Orthodontic treatment is typically initiated at young ages and the most common radiographs at this age are dental. This makes it important to quantify the effects of diagnostic radiographs, in particular of CBCT, due to the fact that the radiation doses are higher compared to conventional radiological methods. So far, the carcinogenic response after low dose radiation exposure is not fully understood in the scientific literature. The aim of our review was to emphasize the main indications of CBCT in orthodontics and to evaluate the radiation doses and potential risks of CBCT irradiation of pediatric patients.
当需要对牙齿和颌面骨结构进行三维分析时，锥形束计算机断层扫描可用于儿科人群。尽管锥形束计算机断层扫描被认为是一种低剂量放射学检查，但电离辐射是一种已知的人类致癌因素。此外，由于年轻患者的放射敏感性较高，生物效应在他们身上更为重要。正畸治疗通常在年轻时开始，这个年龄段最常见的X光片是牙科X光片。鉴于与传统放射学方法相比，锥形束计算机断层扫描的辐射剂量更高，因此量化诊断性X光片，尤其是锥形束计算机断层扫描的影响非常重要。到目前为止，科学文献中对低剂量辐射暴露后的致癌反应尚未完全了解。我们综述的目的是强调锥形束计算机断层扫描在正畸学中的主要适应症，并评估儿科患者锥形束计算机断层扫描照射的辐射剂量和潜在风险。
