摘要

放射線是臨床診斷以及治療計劃和追蹤的重要工具。由於牙科X光是最常見的檢查程序之一，因此輻射危害成為重要的公共衛生議題。即使與其他放射學影像檢查相比，口內放射線攝影的相對風險較小，但是病患可能會經歷多次放射線檢查，因此應考慮輻射曝露的累積效應（cumulative effect）。近來，X光儀器設備和成像系統的技術進步，使得病患的輻射劑量顯著減少。但為了使病患的輻射劑量可以更進一步降低及避免不必要的輻射曝露，採取適當的影像接收器對於牙醫師是必要的措施。此研究蒐集402位牙醫師使用之口內X光機所搭配之影像接收器類型。調查結果顯示，在所有的影像接收器中，57.7%的牙醫師使用數位影像接收器中，42.3%牙醫師使用傳統底片。在數位影像接收器中，有86.2%的牙醫師使用光激磷光板（Photostimulable Phosphor Plates, PSP）、13.8%牙醫師使用電荷耦合器件（charge coupled devices, CCD）。在傳統底片中，有72.3%的牙醫師使用D速度底片（D-speed film）、20.6%的牙醫師使用E速度底片（E-speed film）、7.1%的牙醫師使用F速度底片（F-speed film）。調查數據中，超過一半的開業牙醫師使用數位影像接收器，但在使用傳統底片的牙醫師中，大都沒有遵循輻射防護措施建議，快速底片使用比率偏低，使病患接受不必要的輻射曝露。

Radiography is an important tool for clinical diagnosis, treatment planning and tracing. Since taking X-ray is one of the most common dental examination procedures, radiation hazard has become a crucial public health issue. Although the risk of intraoral radiography is relatively lower than other types of radiographic examinations, patients might have to go through several times of dental radiographic examinations. Therefore, the cumulative effect of radiation exposure should be taken into consideration. Recently, the technical improvement in X-ray equipment and imaging systems significantly reduced the radiation exposure to patients. However, in order to lower the radiation dosage furthermore and to avoid unnecessary exposure, it's necessary for dentists to choose appropriate image receptors. This survey investigated the types of image receptors along with intraoral x-ray machines used by 402 dentists. The result revealed that 57.7% of the investigated dentists used digital image receptors while 42.3% of them used traditional x-ray films. In terms of digital image receptors, 86.2% of the dentists used photostimulable phosphor plates (PSP); 13.8% of them used charge coupled devices (CCD). In terms of traditional films, 72.3% of the investigated dentists used D-speed films; 20.6% of them used E-speed films; 7.1% of them used F-speed films. According to the survey data, more than half of the investigated dental practitioners used digital image receptors. However, from the low utilization rate of fast speed films it's revealed that most of the dentists who used traditional films didn't follow the radiation protection suggestions, causing unnecessary radiation exposure to the patients.
