在牙科学上激光的应用很有趣。激光因其窄的高能脉冲作用于入射处表面可产生组织变化。早期研究用红宝石激光估价高能密度激光辐照牙齿硬组织的损伤效应。Stern等人则报告用CO_2激光辐照,熔化珐琅质表面。并指出由于能使珐琅质溶解和渗透,而在生物学上具 The application of laser in dentistry is very interesting. The laser can generate tissue changes due to its narrow high-energy pulse acting on the incident surface. Early studies used ruby ​​laser to evaluate the damage effect of high energy density laser irradiation on dental hard tissue. Stern et al. Reported that CO2 laser was used to melt the enamel surface. And pointed out that due to make the enamel dissolve and penetration, and in biology
