摘　　要：选用635nm半导体激光器作为光源,研究并实现了激光诱导荧光牙结石诊断系统,通过Visual Basic 6.0开发出数据自动处理软件。该系统能实时诊断牙结石,自动处理实验数据,准确度达93.3%;光源输出功率在59mW时,诊断准确度最高。该系统采用一根光纤同时传输反射光、收集荧光,适合临床诊断的应用。对牙周病临床诊断具有重要指导意义。A 635nm semiconductor laser is selected as the light source and a laser induced fluorescence diagnosis system of tooth is realized, with the automatic data processing soft- ware based on Visual Basic 6.0. The system can realize real - time diagnosis of dental calculus, automatic processing of experimental data, with the accuracy of 93.3 % ; With light source output power of 59mw the highest diagnostic accuracy can be reached. The system uses a fiber to transmit source light and collect fluorescence at the same time, which is suitable for clinical application. This study has important guiding significance to the clinical diagnosis of periodontal diseases.
