The aim of the study was to compare the radiographic diagnosis of approximal carious lesions with visual observations of the approximal surfaces and within drilled Class II cavities (made into the pulp). Sound (n = 28) and carious (n = 123) approximal surfaces of extracted premolars and molars were radiographed. The radiographs were studied by seven observers to diagnose caries. Lesions without cavitation were most often classified as sound (61.3%). When lesions had cavities, the rate of detection increased to 89.1%. Sound surfaces were erroneously classified as carious in 15.7% of cases. Statistically, about 6 out of every 10 qualitative assessments of lesion depth on the basis of radiographs correctly recorded lesions as being in enamel or extending into dentin. The interexaminer variation in radiographic caries diagnoses were mostly due to difference in diagnostic criteria, whereas differences in diagnostic capability were less important.
本研究的目的是将邻面龋损的影像学诊断与邻面视诊以及Ⅱ类洞（制备至牙髓）内的情况进行比较。对拔除的前磨牙和磨牙的健康邻面（n = 28）和龋坏邻面（n = 123）进行了影像学检查。七名观察者对这些X线片进行研究以诊断龋齿。无龋洞的病损最常被判定为健康（61.3%）。当病损有龋洞时，检出率增至89.1%。健康表面在15.7%的病例中被错误地判定为龋坏。从统计学角度来看，基于X线片对病损深度进行的每10次定性评估中，约有6次能正确记录病损是在釉质内还是已延伸至牙本质。影像学龋齿诊断中检查者之间的差异主要是由于诊断标准不同，而诊断能力的差异则不太重要。
