To evaluate the ability of near-infrared light transillumination (NIR-LT) to detect interproximal enamel and dentinal caries lesions compared to clinical-visual inspection aided by fiber-optic transillumination (FOTI).
From 170 Finnish adolescents aged 15 to 17 years, 5,294 interproximal surfaces of premolars and molars were examined first clinical-visually aided by FOTI (VI+FOTI) using the International Caries Detection and Assessment System (ICDAS) classification. Subsequently, the surfaces were examined using NIR-LT. The extent of lesions was determined using the modified NIR-LT classification based on the Söchtig criteria. For the analyses, data on maxillary and mandibular premolars and molars were combined. Distributions of lesions were presented as frequencies. Differences between VI+FOTI and NIR-LT at the tooth and tooth surface levels were analyzed by chi-square and Fisher exact tests. Sensitivity and specificity of the NIR-LT method to detect any lesion was performed using VI+FOTI as the gold standard.
By VI+FOTI, 92.4% surfaces were classified as sound and by NIR-LT, 88.2%. Enamel caries lesions were found on 7.0% of the surfaces by VI+FOTI and on 11.6% by NIR-LT. Nearly double the number of enamel lesions were identified by NIR-LT for all examined teeth groups, except for mandibular molars where this was 1.3-fold. In 66% of the surfaces, the differences between NIR-LT and VI+FOTI findings were statistically significant (P .001). The sensitivity for all teeth of NIR-LT was 48.4% and the specificity was 91.1%.
Radiation-free NIR-LT method shows considerable potential as a supplementary method for early detection of caries lesions among low-caries prevalence adolescents.
与借助光纤透照（FOTI）的临床视觉检查相比，评估近红外光透照（NIR-LT）检测邻面釉质和牙本质龋损的能力。
对170名年龄在15至17岁的芬兰青少年，首先使用国际龋病检测与评估系统（ICDAS）分类，借助FOTI进行临床视觉检查（VI+FOTI），检查5294个前磨牙和磨牙的邻面。随后，使用NIR-LT对这些表面进行检查。基于Söchtig标准的改良NIR-LT分类确定病损范围。分析时，将上颌和下颌前磨牙及磨牙的数据合并。病损分布以频率表示。通过卡方检验和Fisher精确检验分析VI+FOTI与NIR-LT在牙齿和牙面水平的差异。以VI+FOTI作为金标准，进行NIR-LT方法检测任何病损的敏感性和特异性分析。
通过VI+FOTI，92.4%的表面被分类为健康，通过NIR-LT，这一比例为88.2%。通过VI+FOTI，7.0%的表面发现釉质龋损，通过NIR-LT为11.6%。除下颌磨牙为1.3倍外，NIR-LT识别出的所有检查牙齿组的釉质病损数量几乎翻倍。在66%的表面，NIR-LT与VI+FOTI结果之间的差异具有统计学意义（P<0.001）。NIR-LT对所有牙齿的敏感性为48.4%，特异性为91.1%。
无辐射的NIR-LT方法作为低龋患病率青少年龋病早期检测的辅助方法显示出相当大的潜力。
