脉冲Nd：YAG激光被提倡作为在常规牙科手术中提供镇痛的替代方法。因为支持这种说法的证据主要是传闻。摘要利用牙髓电测仪（EPT）进行临床试验，以测量脉冲Nd：YAG激光治疗引起的疼痛效应的程度和持续时间。对21名受试者进行了涉及激光和假手术治疗的双盲交叉实验。用113 mJ脉冲以15脉冲s（-1）（pps）激光治疗3分钟后，5分钟测量的平均反应观察到一个小的（3.6个任意单位）但统计学显著的增加。60分钟后，痛阈恢复到基线值。假治疗后，阈值无统计学显著变化。接受激光和假手术治疗的年龄越大，结果无差异。
The pulsed Nd : YAG laser is advocated as an alternative means of providing analgesia during routine dental procedures. Since the evidence to support this claim is mainly anecdotal. a clinical trial was carried out using an electric pulp tester (EPT) to measure the extent and duration of ally analgesic effect induced by pulsed Nd : YAG laser treatment. A double-blind crossover experiment involving laser and sham treatments was used on 21 subjects. A small (3.6 arbitrary units) but statistically significant increase was observed in the mean responses measured 5 min after laser treatment with 113 mJ pulses at 15 pulses s(-1) (pps) for 3 min. The pain thresholds returned to baseline values after 60 min. No statistically significant changes in threshold were found with the sham treatment. The older in which laser and sham treatment was received made no difference to the results.
