| 摘 要： | 目的：评价Kr:F准分子激光照射牙齿后,对牙体硬组织的影响。方法;通过测量Kr:F准分子激光照射后牙齿硬组织的温度,并与Nd:YAG激光照射组进行比较。结果：10s,60s时,Kr:F准分子激光组牙齿硬组织的温度升高值明显低于Nd：YAG激光照射组（P＜0．01）。在照射10s-60s时间内,Kr:F准分子激光照射后牙齿硬组织的温度变化值也明显低于Nd:YAG激光照射组（P＜0．01）。结论：Kr:F准分子激光牙齿产热较少。

| Abstract: | Objective In order to evaluate the effects of Kr:F excimer laser on dental hard tissue.Methods The temperature of hard tissue of tooth was measured after Kr:F excimer laser irradiation, then compared with Nd:YAG laser. Results The temperature elevated amount of tooth hard tissue being treated with Kr:F excimer laser was much lower than that of Nd:YAG at 10 s and 60 s. And the temperature changed much faster with Nd: YAG than Kr:F excimer laser from 10 s and 60 s during irradiation.Conclusion There is little heat generated during Kr:F excimer laser irradiation on dental hard tissue. |
