本研究测量的有效性和再现性的独立的临床诊断，光纤透照（FOTI），咬翼放射学在邻面龋的诊断。使用提取的前磨牙和磨牙，每个模型包含四个牙齿与六个接触的邻面。首先使用独立的临床检查，然后使用FOTI检查牙齿。然后对模型中的牙齿进行咬翼射线照相并进行检查。1周后重复3次检查。从模型中取出未脱钙牙齿后，制备其组织切片，并检查显示龋齿迹象的牙齿，以确定每个表面的有效疾病状态。诊断阈值为龋穿入牙本质。所有三种方法的重现性均可接受，kappa值超过0.6。所有特异性值均超过0.95。临床诊断（0.38）和咬翼诊断（0.59）的灵敏度之间以及临床和FOTI检查（0.67）之间存在统计学显着差异，但咬翼和FOTI之间无统计学差异。结论：FOTI的有效性至少与咬翼放射学一样高，并且两者都上级独立的临床诊断。
This study measured validity and reproducibility of unaided clinical diagnosis, fibre-optic transillumination (FOTI), and bite-wing radiology in the diagnosis of approximal caries. Sixty models were made using extracted premolars and molars, each containing four teeth with six contacting approximal surfaces. The teeth were examined first using unaided clinical examination and then using FOTI. Bite-wing radiographs were then taken of the teeth set in the models and examined. The three examinations were repeated after 1 week. Histological sections of the undecalcified teeth were prepared following their removal from the models, and those showing signs of caries were examined to give the valid state of disease in each surface. The diagnostic threshold was caries penetrating into dentine. The reproducibility of all three methods was acceptable with kappa values exceeding 0.6. All specificity values exceeded 0.95. Statistically significant differences were seen between sensitivities for clinical (0.38) and bite-wing (0.59) diagnosis and between clinical and FOTI (0.67) examination, but not between bite-wing and FOTI. It is concluded that the validity of FOTI is at least as high as that of bite-wing radiology, and both are superior to unaided clinical diagnosis.
