Cone-beam computed tomography (CBCT) is routinely recommended for dental diagnosis and treatment planning. CBCT exposes patients to less radiation than does conventional CT. Still, lack of proper education among dentists and specialists is resulting in improper referral for CBCT. In addition, aiming to generate high-quality images, operators may increase the radiation dose, which can expose the patient to unnecessary risk. This letter advocates appropriate radiation dosing during CBCT to the benefit of both patients and dentists, and supports moving from the concept of "as low as reasonably achievable" (ALARA) to "as low as diagnostically acceptable" (ALADA).
锥形束计算机断层扫描（CBCT）通常被推荐用于牙科诊断和治疗计划。与传统CT相比，CBCT使患者受到的辐射更少。然而，牙医和专科医生缺乏适当的培训，导致对CBCT的转诊不当。此外，为了生成高质量的图像，操作人员可能会增加辐射剂量，这会使患者面临不必要的风险。这封信主张在CBCT过程中进行适当的辐射剂量控制，以造福患者和牙医，并支持从“合理尽可能低”（ALARA）的概念转变为“诊断可接受的最低水平”（ALADA）。
