摘　　要：目的:研究5种口腔LED光固化灯的光学性能,为临床选择合适的光固化灯提供参考。方法:收集全新的不同型号口腔LED光固化灯5台(SLC-VIIIB(杭州四方医疗器械有限公司),DemiPlus(Kerr),Elipar S10(3M ESPE),Elipar(3M ESPE),VALO(Ultradent)),用辐照度光谱仪对LED光固化灯分别进行波形、波峰光强值及光强变化的测量,使用Bwsped4软件进行对比分析,并采用SPSS 18.0软件对光强值进行统计分析。结果:5台口腔LED光固化灯波形最大吸收峰波长值接近,均趋近于460nm,不同型号的LED光固化灯的光强变化趋势各有特点,但都比较稳定。通过比较,相对光强大小排序如下:VALO>Elipar>Elipar S10>SLC-VIIIB>DemiPlus。结论:初步认为在测试的5台LED光固化灯中,VALO的光学性能最为优秀,吸收光谱范围广,时间短,功率高,效率好。Objective：To study the optical properties of five kinds of dental LED curing lights to provide reference for selecting appropriate curing lights in dental practice.Methods：Five new dental LED curing lights were included in this study,including LC-VIIIB（Hangzhou Sifang Medical Apparatus）,DemiPlus（Kerr）,Elipar S10（3M ESPE）,Elipar（3M ESPE）,and VALO（Ultradent）.The waveform,wave peak and light intensity change of them were tested by the irradiance spectrograph and analyzed by the Bwsped4 software.The light intensity was compared by SPSS 18.Results：The maximum absorption wavelengths of 5lights were all close to 460 nm.The trend of light intensity of each light had its own characteristics,but relatively stable.The intensities in descending order were as follows：VALO〉Elipar〉Elipar S10〉SLC-VIIIB〉DemiPlus.Conclusion：It can be preliminarily concluded that,among 5LED curing lights,the optical property of the VALO is the best for its wide absorption spectrum,short time,high power and good efficiency.
