| 中文摘要: |
| 牙科放射学是口腔医学和放射学的主要分支,对于牙齿和牙周组织病变等的精准诊断起着至关重要的作用。牙科X射线检查是临床最常开展的放射程序之一,牙科X射线设备分为口内牙片机和口外牙科机两种,其中口内牙科摄影用于根尖片拍摄,口外牙科摄影包括口腔全景摄影、头影测量摄影和口腔锥形束CT(CBCT)。不同类型牙科X射线设备的检查模式和受检者有效剂量不同,其中口腔CBCT检查的受检者有效剂量较高。尽管单次牙科X射线检查的受检者有效剂量较低,但频繁接受检查会增加罹患腮腺肿瘤或甲状腺癌的潜在风险。因此,对不同类型牙科X射线检查进行辐射剂量评估与分析,建立不同类型牙科X射线检查的诊断参考水平,可为其临床使用和放射防护提供科学依据与实践指南。 |
| 英文摘要: |
| Dental radiology, a primary branch of oral medicine and radiology, plays a vital role in the accurate diagnosis of pathologies, such as dental and periodontal lesions. Dental X-ray examinations, one of the most common radiology procedures in clinical practice, are performed using intra- and extra-oral dental X-ray equipment. Among these, the former is used for apical radiographs, while the latter is utilized for panoramic radiography, cephalometric radiography, and cone-beam computed tomography (CBCT). Different types of dental X-ray equipment are characterized by varying examination modes and effective doses of patient, with dental CBCT examinations featuring a higher effective dose. Despite the low effective dose of patient under a single dental X-ray examination, frequent exposure may lead to an increased risk of parotid gland tumors or thyroid cancer. Therefore, conducting radiation dose assessment and analysis and establishing diagnostic reference levels for different dental X-ray examinations can provide a scientific basis and a practical guide for clinical practice and radiation protection. |
