本研究的目的是：(1)研究牙齿轻接触对口腔面部触觉检测阈值(TDT)、细丝刺痛检测阈值(FPT)和压痛阈值(PPT)的影响；(2)研究这种影响对触觉和痛觉的性别差异。20名健康志愿者参加了实验。用Semmes-Weinstein单丝测量咬肌(MM)面颊皮肤(CS)和大鱼际皮肤(TS)掌侧皮肤的TDT和FPT。使用压力测痛仪在MM的中央部分测量PPT。作为对照，分别在保持轻度牙齿接触5min(会话1)和保持下颌放松5min(会话2)前后测量各项参数。尽管这些参数没有显著的时间效应，但实验条件对男性和女性的TDT都有显著的影响(P<；0.001)。男性左侧CS和TS的FPT显著高于女性(P<0.001)，MM的PPT显著高于女性(P<；0.01)。这些结果表明，女性对疼痛的敏感度(FPT、PPT)高于男性。虽然感觉习惯化的性别差异不显著，但女性咬合/不咬合后TDT的增加幅度较大，值得进一步研究。
The aim of this study was (i) to examine the effect of light tooth contact as in diurnal tooth clenching on the tactile detection threshold (TDT), the filament-prick pain detection threshold (FPT) and the pressure pain threshold (PPT) in the oro-facial region and (ii) to examine the possible gender difference in this effect on the tactile and pain perception. Twenty healthy volunteers participated. The TDT and the FPT were measured by means of Semmes-Weinstein monofilaments, on the cheek skin (CS) overlying the masseter muscles (MM) and on the skin overlying the palm side of the thenar skin (TS). The PPT was measured at the central part of the MM using a pressure algometer. Each parameter was measured before and after keeping light tooth contact for 5 min (session 1) and after keeping the jaw relaxed for 5 min (session 2) as a control. Although there were no significant session effects on any of the parameters, there were significant effects of experimental condition on the TDT in both men and women (P < 0.001). Men had a significant higher FPT of the left CS (P < 0.05) and TS (P < 0.01) and a significant higher PPT of the MM than women (P < 0.001). These results illustrate that sensitivity to pain (FPT, PPT) was higher in women than in men. Although there were no significant gender differences in habituation of sensory perception, the increase of TDT after clenching/no clenching was larger in women, which warrants further study.
