The accurate detection of approximal caries is generally difficult. The aim of this study was to assess the ability of the pen-type laser fluorescence device (LF pen) to detect approximal carious lesions in comparison to bitewing radiographs (BW).
Three hundred forty-one tooth surfaces were diagnosed in 20 patients with an average age of 26.70 (±2.82) years. Each test tooth was sequentially assessed by a single calibrated examiner using visual inspection, BW, and the LF pen. Radiographs were used as the gold standard to calculate an appropriate cut-off.
Sensitivity, specificity and accuracy values for cut-off limits of 15, measured by the LF pen were compared using the chi test (McNemar test). For approximal caries at D3 level, the highest values of specificity and sensitivity were observed for the LF pen at a cut-off value of 15 (96.8 and 83.0 %) and for visual inspection (99.3 and 4.3 %).
Within the limitations of this study, dentin caries on approximal surfaces could be detected equally well by the LF pen as by the bitewing radiographs. Therefore, the LF pen can be recommended as an alternative to radiographs for the detection of approximal caries in a regular dental practice setting.

邻面龋的准确检测通常较为困难。本研究的目的是评估笔式激光荧光装置（LF笔）与咬合翼片（BW）相比检测邻面龋损的能力。
对20名平均年龄为26.70（±2.82）岁的患者的341个牙面进行诊断。由一名经过校准的检查者依次使用视觉检查、BW和LF笔对每颗受试牙齿进行评估。以X线片作为金标准来计算合适的截断值。
使用卡方检验（麦克尼马尔检验）比较LF笔测量的截断值为15时的灵敏度、特异度和准确度值。对于D3级邻面龋，LF笔在截断值为15时特异度和灵敏度最高（分别为96.8%和83.0%），视觉检查的特异度和灵敏度分别为99.3%和4.3%。
在本研究的局限性范围内，LF笔检测邻面牙本质龋的效果与咬合翼片相当。因此，在常规牙科诊疗环境中，LF笔可作为X线片检测邻面龋的替代方法推荐使用。
