早期龋的探测及诊断是龋病防治的重要方面。激光荧光法是新型龋诊断方法之一,它是利用龋坏部位激发的荧光强度远高于正常牙齿硬组织,定量分析牙体脱矿程度。激光荧光法灵敏度高、准确度高、可靠性好及无创性,可作为诊断早期龋的有效辅助手段。本文就激光荧光法诊断早期龋的原理、诊断价值、临床应用以及影响因素等研究进展作一综述。
Detection and diagnosis of early caries is an important aspect of caries prevention and treatment. Laser fluorescence method is one of the new methods of caries diagnosis. It uses the fluorescence intensity of carious parts to be much higher than that of normal hard tissues, and quantitatively analyzes the degree of tooth demineralization. Laser fluorescence method with high sensitivity, high accuracy, reliability and noninvasive, can be used as an effective adjunct to diagnose early caries. This article reviewed the research progress of laser fluorescence spectroscopy in the diagnosis of early caries, its diagnostic value, clinical application and influencing factors.
