To assess the influence of new European Union (EU) legislation on radiation doses in intraoral dental radiography in Spain.
A total of 10 109 official reports from Spanish dental offices covering the period 1996-2003 were analysed.
The results point to a dose reduction of 19% in 7 years, with a mean dose of 3.11 mGy being administered in 2003. The third quartile value in 2002 was 4.8 mGy. Taking the EU recommended dose of 4 mGy as standard, 73.3% (2002) and 77.3% (2003) of installations are in compliance with the EU recommendations in Spain. However, there has been no further reduction in the last 3 years. The results showed that Ultraspeed dental X-ray film was used by 77.6% of the dentists in 1996-1997 and 82.3 in 2003. There was infrequent use of E-speed films (0.6%) and F-speed films (9.6%) in 2003. Statistical analysis pointed to significant differences between the doses administered and the type of processing used, the lowest exposures being measured in digital systems, which used significantly lower doses than both manual and automatic development, and when conventional radiographic films were used.
The introduction of new legislation has resulted in a gradual reduction in the dose administered in intraoral dental radiology in Spain.
评估欧盟新法规对西班牙口腔牙科X线摄影辐射剂量的影响。
分析了西班牙牙科诊所1996 - 2003年期间的10109份官方报告。
结果表明7年内剂量降低了19%，2003年的平均剂量为3.11毫戈瑞。2002年的第三四分位数为4.8毫戈瑞。以欧盟推荐剂量4毫戈瑞为标准，西班牙73.3%（2002年）和77.3%（2003年）的设备符合欧盟建议。然而，在过去3年中剂量没有进一步降低。结果显示，1996 - 1997年77.6%的牙医使用超高速牙科X线胶片，2003年这一比例为82.3%。2003年很少使用E速胶片（0.6%）和F速胶片（9.6%）。统计分析表明所给予的剂量与所使用的冲洗类型之间存在显著差异，数字系统测量的曝光量最低，其使用的剂量明显低于手动和自动显影以及使用传统X线胶片时的剂量。
新法规的引入导致西班牙口腔牙科放射学中所给予的剂量逐渐降低。
