This survey reports on successful efforts to establish a quality assurance (QA) program for 50 intraoral x-ray units in the public and private sectors in the region of Achaia, Greece. It was conducted in 2 phases, in 1996 and in 2003, including on-site inspections, QA tests, and standard questionnaires. The aim of the study was to assess equipment conditions, knowledge, and adoption of radiographic QA guidelines by general dentists and, more importantly, the impact of the recommendations and training provided.
The tested parameters focused on radiation protection, equipment maintenance, film speed used, film processing conditions, and radiologic characteristics such as voltage, radiation leakage, type of collimation, source-to-skin distance, timer accuracy, and entrance dose.
The data gathered in 1996 demonstrate minimal compliance with equipment function requirements and radiation safety measures. 1 The comparative evaluation of all the parameters gathered from the 2 surveys, indicated that in 2003 the vast majority of the dentists followed the recommendations given in 1996. Only 2 dentists persisted in neglecting the guidelines.
本调查汇报了为希腊阿哈伊亚地区公共和私营部门的50台口腔内X光设备建立质量保证（QA）计划的成功努力。该调查分两个阶段进行，分别在1996年和2003年，包括现场检查、QA测试和标准问卷调查。本研究的目的是评估设备状况、普通牙医对放射照相QA指南的了解和采用情况，更重要的是评估所提供建议和培训的影响。
测试参数集中在辐射防护、设备维护、使用的胶片速度、胶片冲洗条件以及放射学特征，如电压、辐射泄漏、准直类型、源皮距、定时器准确性和入口剂量。
1996年收集的数据表明，对设备功能要求和辐射安全措施的遵守程度极低。对两次调查收集的所有参数进行的比较评估表明，2003年绝大多数牙医遵循了1996年给出的建议。只有2名牙医仍无视这些指南。
