利用蓝发光二级管诱导荧光检测龋损的研究

Real-time Detection of Dental Caries by a Violet Light-emitting Diode Induced Fluorescence

目的:利用蓝发光二级管诱导荧光检测龋损。方法:将30颗牙随机分为3组:正常对照组(N组);实验组,龋坏组(P1组);实验对照组,龋损去除组(P2组)。结果:荧光检测结果显示P1组与N组荧光光谱有显著差异,P2组与P1组荧光光谱明显不同,P2组与N组荧光光谱相似。结论:以本方法可以早期发现邻面的早期龋损,继发龋或隐匿性龋,另外在深龋去腐过程中,同时进行检测,还可以防止去腐过度和意外穿髓。

Objective： To detect dental caries objectively using a violet light -emitting diode （LED） induced fluorescence. Methods： Thirty extracted human teeth with dental caries were randomly divided into three groups. Control group （N） and two experimental groups （ P1 and P2 ）. P1 group was composed of ten teeth with natural dental caries. P2 group was caries that had been removed. Results： The wave of P1 group was significant deviated from that of N group , but P2 group was silimar to N group. Conclusion： This method can detect dental caries immediately , and can prevent excess removing detritus or pulp exposed.
