摘　　要：背景:评估光导荧光技术辅助诊断隐裂牙的可行性,探讨隐裂牙诊断新技术。方法:37例通过咬诊、显微镜等检查确诊为隐裂牙的患牙纳入本实验,使用DIAGNOdent 2190对患牙进行光导荧光检查,记录荧光指数。用相同方法检测对照牙。应用独立样本t检验比较隐裂组和对照组荧光指数。结果:隐裂组和对照组荧光指数比较差异有统计学意义(P<0.001);隐裂组患牙的荧光指数均位于早期龋范围。结论:光导荧光技术可以用于辅助诊断隐裂牙;隐裂牙裂纹中存在不同程度的早期龋,荧光指数可以作为临床医生制定治疗计划和判断预后的依据。Objective： To investigate the effectiveness of laser fluorescence on the diagnosis of cracked teeth, and to explore new techniques for the diagnosis of cracked teeth. Methods： Thirty-seven cracked teeth diagnosed by means of bite tests and microscopic detection were included in this experiment. DIAGNOdent 2190 was used to detect these cracked teeth, and the fluorescence was recorded. The control teeth were detected by the same method. Results： There was a significant difference on the fluorescence between the cracked teeth and the control teeth （P〈0.001）. The fluorescence values of the cracked teeth were all within the range of early caries. Conclusion： Laser fluorescence can be used to diagnose the cracked teeth. There are varying degrees of early caries in the cracks, and fluorescence can be used to develop treatment plans and assess prognosis.
