Dental cone-beam computed tomography (CBCT) received regulatory approval in Japan in 2000 and has been widely used since being approved for coverage by the National Health Insurance system in 2012. This imaging technique allows dental practitioners to observe and diagnose lesions in the dental hard tissue in three dimensions (3D). When performing routine radiography, the examination must be justified, and optimal protection should be provided according to the ALARA (as low as reasonably achievable) principles laid down by the International Commission on Radiological Protection. Dental CBCT should be performed in such a way that the radiation exposure is minimized and the benefits to the patient are maximized. There is a growing demand for widespread access to cutting-edge health care through Japan's universal health insurance system. However, at the same time, people want our limited human, material, and financial resources to be used efficiently while providing safe health care at the least possible cost to society. Japan's aging population is expected to reach a peak in 2025, when most of the baby boomer generation will be aged 75 years or older. Comprehensive health care networks are needed to overcome these challenges. Against this background, we hope that this text will contribute to the nation's oral health by encouraging efficient use of dental CBCT.
口腔锥形束 CT（CBCT）于 2000 年在日本获得监管批准，并于 2012 年被国家健康保险系统批准覆盖后得到广泛应用。这种成像技术使牙科医生能够在三维（3D）观察和诊断牙硬组织的病变。在进行常规放射检查时，必须进行正当性检查，并应根据国际放射防护委员会（ICRP）规定的“合理可达尽量低”（ALARA）原则提供最佳防护。应尽可能减少口腔 CBCT 的辐射暴露，并使患者受益最大化。日本全民健康保险制度要求广泛获得先进的医疗保健服务，因此对其的需求日益增长。然而，与此同时，人们希望在以尽可能低的社会成本提供安全的医疗保健的同时，高效利用我们有限的人力、物力和财力资源。预计日本人口老龄化将在 2025 年达到高峰，届时大多数婴儿潮一代将年满 75 岁或以上。需要建立全面的医疗保健网络来应对这些挑战。有鉴于此，我们希望本文能通过鼓励口腔 CBCT 的有效利用，为国家的口腔健康做出贡献。
