A conservative, noninvasive or minimally invasive approach to clinical management of dental caries requires diagnostic techniques capable of detecting and quantifying lesions at an early stage, when progression can be arrested or reversed. Objective evidence of initiation of the disease can be detected in the form of distinct changes in the optical properties of the affected tooth structure. Caries detection methods based on changes in a specific optical property are collectively referred to as optically based methods. This paper presents a simple overview of the feasibility of three such technologies for quantitative or semiquantitative assessment of caries lesions. Two of the techniques are well-established: quantitative light-induced fluorescence, which is used primarily in caries research, and laser-induced fluorescence, a commercially available method used in clinical dental practice. The third technique, based on near-infrared transillumination of dental enamel is in the developmental stages.
对龋齿进行保守、非侵入性或微创的临床管理方法，需要能够在疾病早期阶段检测和量化病变的诊断技术，因为在此阶段病变进展可以被阻止或逆转。疾病起始的客观证据可以以受影响牙齿结构光学特性的明显变化形式被检测到。基于特定光学特性变化的龋齿检测方法统称为光学方法。本文简要概述了三种此类技术用于龋齿病变定量或半定量评估的可行性。其中两种技术已成熟：定量光诱导荧光，主要用于龋齿研究；激光诱导荧光，一种用于临床牙科实践的商业可用方法。第三种技术基于牙釉质的近红外透照，尚处于开发阶段。
