摘　　要：采用405nm激光器和635nm半导体激光器为激发光源,对正常牙齿和牙齿牙结石覆盖区激发,对所得的荧光光谱进行分析;再利用双波长荧光比例探测法诊断是否患有牙结石。结果表明,采用双波长荧光比例探测法,其灵敏度达92.2%,准确度达99%,可为临床诊断提供有效的参考数据。Dental calculus is one of the most important causes of periodontal disease, so di-agnosis of dental calculus, especially subgingival calculus, is crucial for the therapy. One ex-citation wavelength is usually used in previous study for diagnosis of dental calculus. To in-crease the sensitivity of detection,405nm and 635nm semiconductor laser were repectivelyused to excitedental calculusnormal coverage area. The fluorescence spectra obtained wereanalyzed and summarized to prove the prescence of dental calculus by using the proportionof fluorescent detection method. This study shows that the sensitivity and specificity is re-spectively 92. 2% and 99% by using dual-wavelength fluorescence ratio detection method.This study may provide a favorable reference data for clinical diagnosis.
