The effect of altering the distance between light tip and outer layer of composite (DLR) on the depth of composite cure with a range of low to high light intensity curing lamps and with different types of light unit is of interest. Three LED units (T= Freelight,U = Ultrablue IS, V = Coltolux LED, one PAC unit (S=PAC) and three halogen light-curing units (P = XL2500, Q = HelioluxVL, R = Visiolux) were analyzed. A human molar tooth that was separated mesio-distally to buccal and lingual halves was used to create a natural tooth sample. Data shows that the depth of cure for the composite material decreased as the distance between the repair and the light source increased. There was no appreciable difference in performance between the LEDs and the other kinds of curing lamps as the distance between them grew.
改变光尖与复合材料外层之间的距离（DLR）对一系列低到高光照强度固化灯以及不同类型光单元下复合材料的固化深度的影响备受关注。分析了三个发光二极管单元（T = Freelight，U = Ultrablue IS，V = Coltolux LED）、一个等离子弧光固化单元（S = PAC）和三个卤素光固化单元（P = XL2500，Q = HelioluxVL，R = Visiolux）。使用一颗近远中向分离为颊侧和舌侧两半的人类磨牙来制作天然牙齿样本。数据表明，随着修复体与光源之间距离的增加，复合材料的固化深度降低。随着发光二极管与其他类型固化灯之间距离的增加，它们在性能上没有明显差异。
