A study was conducted to compare the compressive strength, diametral tensile strength, transverse flexural strength, and flexural modulus of a microfilled and a small particle composite resin restorative material following argon laser and conventional visible light polymerization techniques. All physical properties examined in this study were enhanced by laser polymerization. The diametral tensile strength of both types of restorative materials was significantly greater following laser polymerization, as were the transverse flexural strength and the flexural modulus of the microfilled resin restorative material. Additionally, these results were obtained with a laser polymerization time that was one-fourth that used for visible light activation. It was concluded that the argon laser is a potentially advantageous means of initiating the polymerization of dental composite resin restorations.
进行了一项研究，以比较微填料复合树脂修复材料和小颗粒复合树脂修复材料在氩激光和传统可见光聚合技术下的抗压强度、径向拉伸强度、横向弯曲强度和弯曲模量。本研究中检测的所有物理性能通过激光聚合得到增强。两种修复材料的径向拉伸强度在激光聚合后均显著提高，微填料树脂修复材料的横向弯曲强度和弯曲模量也是如此。此外，获得这些结果所用的激光聚合时间仅为可见光激活时间的四分之一。得出的结论是，氩激光是引发牙科复合树脂修复体聚合的一种潜在有利手段。
