In this study, the clinical and radiographic material of two groups of 17- and 20-yr-old adolescents, born either in 1970 or in 1976, was compared to study changes in the prevalence of occlusal dentine caries and to determine the additional value of the bitewing radiographs. The first and second molars of 478 participants were included. Clinical data were derived from an epidemiological project. Two examiners judged the bitewing radiographs, of which about 10% was examined by both. The overall Cohen's kappa for interexaminer agreement was 0.87. The prevalence of occlusal caries had not changed for the two age groups; after clinical and radiographic examination, around 33% of the occlusal surfaces of the 17 yr olds and around 25% of the 20 yr olds exhibited dentine caries. The clinical prevalence of occlusal caries in first and second molars was highly underestimated when compared with the radiographs. In the 1976 group, more sealants were recorded during the clinical examination. On the bitewing radiographs, radiolucencies were found underneath one-half of the sealants of the 17 yr olds and underneath one quarter of the sealants present in the 20 yr olds.
在本研究中，对两组分别出生于1970年和1976年的17岁及20岁青少年的临床和影像学资料进行比较，以研究咬合面牙本质龋患病率的变化，并确定咬合翼片的附加价值。纳入了478名参与者的第一恒磨牙和第二恒磨牙。临床数据来自一项流行病学项目。两名检查者对咬合翼片进行判读，其中约10%的片子由两人共同检查。检查者间一致性的总体Cohen's kappa值为0.87。两个年龄组的咬合面龋患病率均未发生变化；经临床和影像学检查后，17岁组约33%的咬合面以及20岁组约25%的咬合面出现牙本质龋。与X线片相比，第一恒磨牙和第二恒磨牙咬合面龋的临床患病率被严重低估。在1976年出生的组中，临床检查时记录到更多的窝沟封闭剂。在咬合翼片上，17岁组一半以上的窝沟封闭剂下方发现有透射区，20岁组四分之一的窝沟封闭剂下方发现有透射区。
