The argon laser is an alternative light source that can be used for the photopolymerization of resin-based dental materials and for tooth bleaching. The argon laser emits specific laser lines with wavelengths that correspond to the absorption peak of camphoroquinone, the initiator of polymerization for the adequate photocuring of resin composite. The collimated beam of the argon laser does not decrease with distance and an optical fiber has access to all cavity areas. In addition, the temperatures produced by an argon laser when curing resin-based materials and performing in-office tooth bleaching are significantly lower than those of conventional photocuring units. Argon is one of the three dental laser wavelengths that have been cleared by the FDA for tooth whitening. This article reviews the literature to examine the role that argon lasers can play in dental treatment.
氩激光是一种可替代的光源，可用于树脂基牙科材料的光聚合反应和牙齿美白。氩激光发射特定的激光谱线，其波长与樟脑醌的吸收峰相对应，樟脑醌是用于树脂复合材料充分光固化的聚合引发剂。氩激光的准直光束不会随距离而减弱，并且光纤能够照射到所有的窝洞区域。此外，在固化树脂基材料和进行诊室牙齿美白时，氩激光产生的温度明显低于传统光固化设备。氩是已被美国食品药品监督管理局（FDA）批准用于牙齿美白的三种牙科激光波长之一。本文回顾了相关文献，以探讨氩激光在牙科治疗中所能发挥的作用。
