【摘要】 目的 探讨提高X线照片质量和X线诊断水平的必要性和重要性。方法 ①国际标准ISO认证专用牙片 (以下简称专用牙片 )与普通胶片改裁牙片 (以下简称普通牙片 )曝光剂量的比较 ;②工作数量总结及统计分析 ;③对口腔颌面部及其它部位X线照片进行质量评定。结果 ①用专用牙片投照的曝光剂量明显少于普通牙片投照的曝光剂量 ,减少了辐射量 ,提高了X线照片影像的对比度和清晰度 ,延长了机器的使用寿命 ;②工作数量统计分析结果显示 ,平均 (对比 )增长速度为 6 .2 4% ;③X线照片质量评定结果显示 :一级片率为 48.95 % ,一、二级片率之和为 90 .95 % ,废片率为 0 .8%。结论实施质量保证、质量控制计划 ,是一项长期的、细致的系统工程

【Abstract】 Objective To test the relationship between quality assurance in oral and maxillofacial radiology and the accuracy of diagnosis.Methods ①The exposure doses were compared between professional dental films (international standards) and conventional films;②The whole nmubers of dental films taken within six years in our department were statistically analyzed;③Image quality of oral and maxillofacial radographs was evaluated.Results ①The exposure doses using professional films were lower than using conventional films;②The average increasing ration of dental films was 6.24% ,it indicated that quantity of dental films increased under the control of quality;③The quality evaluation showed that the ratio of the first grade of image was 48.95% ,the total of the first and the second grade was 90.95% ,and the ratio of waste films was 0.8% .Conclusion A quality assurance program includes both quality control techniques and quality administration procedures.Quality assurance will consistently produce high-quality and informative images with minimum exposure to the dental patients and dental personnel.
