研究了一种提高牙科光固化单元（LCU）辐射光均匀性的方法，及其对光活化复合树脂聚合的影响。使用石英钨卤、等离子弧和发光二极管LCU，并采用混合管和漫射屏等附加光学元件来减少辐射光的不均匀性。测量来自光导尖端的光强度在整个光导尖端的分布，以及随 LCU 发射的光激活树脂的表面硬度分布。虽然附加的光学元件导致光强度衰减13.2-25.9%，但改进后的LCU的光强度均匀性得到显着改善，并且树脂表面硬度的均匀性也得到改善。我们的结果表明，向 LCU 添加光学元件可能是减少 LCU 辐射光不均匀性的简单而有效的方法。
A method for improving the uniformity of the radiation light from dental light-curing units (LCUs), and the effect on the polymerization of light-activated composite resin are investigated. Quartz-tungsten halogen, plasma-arc, and light-emitting diode LCUs were used, and additional optical elements such as a mixing tube and diffusing screen were employed to reduce the inhomogeneity of the radiation light. The distribution of the light intensity from the light guide tip was measured across the guide tip, as well as the distribution of the surface hardness of the light-activated resin emitted with the LCUs. Although the additional optical elements caused 13.2-25.9% attenuation of the light intensity, the uniformity of the light intensity of the LCUs was significantly improved in the modified LCUs, and the uniformity of the surface hardness of the resin was also improved. Our results indicate that the addition of optical elements to the LCU may be a simple and effective method for reducing inhomogeneity in radiation light from the LCUs.
