OBJECTIVE To compare near infrared transillumination device, DIAGNOcam (DC) and bitewing radiography (BW) for the detection of proximal caries. MATERIALS AND METHODS This retrospective analysis of DC and BW images of 18 students in dental medicine who had consented to the anonymous use of their dental record. The data included BW and DC images performed for a check-up in 2013, and corresponding follow-up images performed in 2015. Two observers rated 376 proximal surfaces on a 4-level dentin lesion scale and reached a unanimous rating for each surface. Calculated measures of agreement for each assessment method over time provided the reproducibility of the information obtained by each method. RESULTS Agreement between 2013 and 2015 within each method was excellent (intraclass correlation coefficient, BW: 0.86, DC: 0.90). Agreement between DC and BW was similar for dentin lesion detection, but was low for enamel caries detection; DC detected more enamel caries than BW. Agreement between DC and BW was modest (0.33 in 2013 and 0.36 in 2015), chiefly because DC identified more enamel caries. CONCLUSION This study shows that DC is as reliable as BW to detect proximal dentin lesions. DC detects proximal enamel lesions at an earlier stage than BW. DC enables clinicians to differentiate lesions limited to the enamel from lesions that have reached the enamel dentin junction. Regular monitoring with DC should help provide individualized preventive measures and early non-invasive caries management. CLINICAL SIGNIFICANCE The early detection of enamel lesions with near infrared transillumination can help clinicians undertake early non invasive treatments to prevent or slow down the progression of initial proximal lesions.

与放射照相相比，近红外透射法可以检测和监测近端龋齿：一项临床回顾性研究。

目的比较DIAGNOcam（DC）和咬合射线照相术（BW）的近红外透射仪，以检测近端龋齿。材料与方法这项回顾性分析了18名同意匿名使用其牙科记录的牙科医学专业学生的DC和BW图像。数据包括2013年进行检查的BW和DC图像，以及2015年进行的相应随访图像。两名观察员对4个级别的牙本质病变量表中的376个近端表面进行了评分，并获得了每个表面的一致评分。随着时间的推移，每种评估方法的一致性计算量提供了每种方法获得的信息的可重复性。结果每种方法在2013年至2015年之间的一致性极好（类内相关系数，BW：0.86，DC：0.90）。DC和BW之间的一致性在牙本质病变检测中相似，但在牙釉质龋齿检测中一致性较低。DC检测到的龋齿比BW多。DC和BW之间的协议不多（2013年为0.33，2015年为0.36），主要是因为DC发现了更多的牙釉质龋齿。结论这项研究表明DC在检测牙本质近端病变方面与BW一样可靠。DC比BW更早地检测到近端牙釉质病变。DC使临床医生能够将局限于牙釉质的病变与已经到达牙釉质牙本质交界处的病变区分开。用DC进行定期监测应有助于提供个性化的预防措施和早期的非侵入性龋齿管理。
