在人类实验性疼痛研究中使用不同的激光进行刺激，为评价细神经纤维功能提供了一种灵敏的方法。在本研究中，将感觉阈值和疼痛阈值与氩激光、铜蒸汽激光、Nd：YAG激光和CO2激光刺激多毛皮肤和口腔粘膜进行了比较。研究了激光类型、刺激部位、表面颜色和刺激参数（激光束直径和脉冲持续时间）对阈值的影响。在两个表面上发现四种激光之间的阈值存在显着差异;然而，当使用相同的激光时，皮肤和舌头上的阈值之间没有显着差异。观察结果表明，受激组织的波长相关光学特性影响阈值确定。此外，结果表明，时间和空间的总和机制可能存在激光诱导的温暖和疼痛的看法。激光刺激可能是一种新的工具，调查的起源和成因的各种口面部疼痛综合征。
The use of different lasers for stimulation in human experimental pain research has provided a sensitive method for evaluation of thin nerve fiber functions. In this study, sensory and pain thresholds were compared to argon‐, copper vapour‐, Nd:YAG‐, and CO2 laser stimulation on hairy skin and on oral mucosa. The influence on thresholds with respect to laser type, stimulation site, surface colour, and stimulus parameters (laser beam diameter and pulse duration) was investigated. Significant differences in thresholds between the four lasers were found on both surfaces; however, no significant differences existed between thresholds on the skin and on the tongue when the same laser was used. The observations imply that wavelength‐dependent optical properties of the stimulated tissue influence on threshold determinations. Furthermore, the results indicate that temporal and spatial summation mechanisms may exist for laser induced warmth and pain perceptions. Laser stimulation may be a new tool for the investigation of origin and genesis of various orofacial pain syndromes.
