The hypothesis of the present study was that previous experience of caries may serve as an indicator for individualised bitewing examinations in 15-19-old adolescents. One hundred adolescents, all 19 years old, were randomly selected from the files of public dental clinics in the County of Orebro. For 93 adolescents the total number of radiographs were summed for every patient from the age of 3 to 19 by assessing the files of public dental clinics and by assessing the files of the dental radiology department. All sets of bitewing radiographs from 14 up to and including the age of 19 were assessed with respect to approximal caries. The average number of intraoral radiographs exposed in a patient from the age of 3 through 19 was 24.4. It was shown that 70 to 80% of 14-19-year-old-adolescents had had a bitewing examination every year. The decision to perform a bite-wing examination in a 15-year-old was significantly correlated to the number of surfaces with initial caries at the age of 14. In the other age groups, none of the investigated variables was found to be significantly correlated to the performance of radiographic examinations.
本研究的假设是，龋齿既往经历可能作为15至19岁青少年进行个性化翼片检查的一个指标。从厄勒布鲁县公共牙科诊所档案中随机选取了100名青少年，均为19岁。对于93名青少年，通过评估公共牙科诊所档案和牙科放射科档案，汇总每位患者从3岁到19岁的X光片总数。对所有从14岁直至19岁（含19岁）的翼片进行邻面龋齿评估。一名患者从3岁到19岁期间口腔内X光片的平均曝光次数为24.4次。结果显示，70%至80%的14至19岁青少年每年都接受过翼片检查。在15岁青少年中进行翼片检查的决定与14岁时初始龋齿的牙面数量显著相关。在其他年龄组中，未发现任何调查变量与X光检查的进行存在显著相关性。
