The aim of our study was to evaluate the validity of the digital imaging fiber-optic transillumination (DIFOTI) method in comparison with clinical visual examination (CV) and bitewing (BW) radiography on detecting caries lesions on proximal surfaces of teeth.
Proximal tooth surfaces of premolars and molars ( = 2,103) of 91 voluntary university students aged from 18 to 30 years were examined with CV, BW radiography, and the DIFOTI method.
DIFOTI detected more initial and manifested caries lesions compared with CV and BW. Of the analyzed tooth surfaces, 69.8% were classified as sound by DIFOTI, 80.3% by BW, and 91.6% by CV. Initial caries lesions were found in 21.2% of the surfaces by DIFOTI, in 14.1% by BW, and in 6.2% by CV, whereas the proportions for manifested dental caries lesions were 9.0%, 5.6%, and 2.2%, respectively. The interexaminer agreement regarding the DIFOTI findings between an experienced clinician and a fifth-year dental student was high: = 0.67 for initial and = 0.91 for manifested caries lesions.
The noninvasive DIFOTI method seems to offer a potential tool for everyday clinical practice. In clinical use, DIFOTI finds well even initial caries lesions on proximal surfaces, thus providing an instrument for detecting lesions potential for arresting as well as for monitoring the outcome after preventive measures.
我们研究的目的是评估数字成像光纤透照（DIFOTI）方法与临床视觉检查（CV）和咬合翼片（BW）X线摄影在检测牙齿邻面龋损方面的有效性。
对91名年龄在18至30岁的自愿参与的大学生的前磨牙和磨牙的2103个邻面进行了CV、BW X线摄影和DIFOTI方法检查。
与CV和BW相比，DIFOTI检测到更多的早期龋损和已表现出的龋损。在分析的牙面中，DIFOTI将69.8%的牙面分类为正常，BW为80.3%，CV为91.6%。DIFOTI在21.2%的牙面发现了早期龋损，BW为14.1%，CV为6.2%，而已表现出的龋齿损的比例分别为9.0%、5.6%和2.2%。一位经验丰富的临床医生和一名牙科五年级学生之间关于DIFOTI检查结果的检查者间一致性很高：早期龋损的kappa值为0.67，已表现出的龋损为0.91。
无创的DIFOTI方法似乎为日常临床实践提供了一种潜在工具。在临床应用中，DIFOTI甚至能很好地发现邻面的早期龋损，从而提供一种检测有阻止可能的龋损以及监测预防措施后结果的手段。
