目的:探讨健康青年人群颌面部温度定量感觉的可重复性,以及不同部位、性别之间的差异。方法 :采用温度定量感觉测试对26例受试者(男12例、女14例)左、右侧咬肌区及左侧手背部表面皮肤进行检查,测试冷感觉阈值(cold detection thresholds,CDT)、热感觉阈值(warm detection thresholds,WDT)、冷痛觉阈值(cold pain thresholds,CPT)、热痛觉阈值(hot pain thresholds,HPT),每个部位重复测试3次,每次间隔10 min;每次给予3个刺激,每个刺激间隔4 s;1周后重复相同的测试,应用组内相关系数(intraclass correlation coefficient,ICC)评价不同时间间隔感觉阈值的重复性,重复性测试的方差分析比较不同的性别、受试部位及时间间隔对感觉阈值的影响。结果:3个测试周期的温度阈值均显示了良好的一致性(ICCCDT:0.642~0.869,ICCWDT:0.591~0.723,ICCCPT:0.672~0.967,ICCHPT:0.757~0.917);间隔1周时间的阈值也显示良好的一致性(ICCCDT:0.508~0.772,ICCWDT:0.560~0.885,ICCCPT:0.629~0.872,ICCHPT:0.581~0.662)。左右侧面部的感觉没有明显差异(PCDT=0.398,PWDT=0.223,PCPT=0.264,PHPT=0.943);面部较左手背部皮肤对痛觉温度刺激敏感(PCPT=0.003,PHPT=0.004);女性较男性对痛觉温度刺激敏感(PCPT=0.008,PHPT=0.016)。结论 :温度定量感觉测试具有较好的可重复性,可以用于颌面部体表感觉的测量;面部较左手背部皮肤对痛觉温度刺激敏感;女性较男性对痛觉温度刺激敏感。
Objective: To investigate the reproducibility of quantitative sensory temperature of maxillofacial area in healthy young people and the differences among different parts and genders. Methods: Twenty-six subjects (12 males and 14 females) were examined with temperature quantitative sensory test on the left and right masseter area and the left hand dorsal surface skin to test cold detection thresholds (CDT) , Warm detection thresholds (WDT), cold pain thresholds (CPT) and hot pain thresholds (HPT). Each site was repeated 3 times with an interval of 10 min each time. Three stimuli were given at 4 s intervals, and the same test was repeated one week later. The intraclass correlation coefficient (ICC) was used to evaluate the repeatability of the sensory threshold at different time intervals. The variance analysis of the repetitive test was different The gender, the site of the test and the time interval on the sensory threshold. RESULTS: The temperature thresholds for the three test cycles showed good agreement (ICCCDT: 0.642-0.869, ICCWDT: 0.591-0.723, ICCCPT: 0.672-0.967, ICCHPT: 0.757-0.917); the threshold at 1 week interval also showed Good agreement (ICCCDT: 0.508-0.772, ICCWDT: 0.560-0.885, ICCCPT: 0.629-0.872, ICCHPT: 0.581-0.662). (PCPT = 0.398, PWDT = 0.223, PCPT = 0.264, PHPT = 0.943). The skin of the left lower back was more sensitive to hyperalgesia (PCPT = 0.003, PHPT = 0.004) than the male ones Pain sensation stimulated temperature sensitivity (PCPT = 0.008, PHPT = 0.016). CONCLUSION: The temperature quantitative sensory test has good repeatability and can be used for the measurement of maxillofacial body surface sensation. The facial skin is more sensitive to pain sensation than the left posterior dorsal skin. Women are more sensitive to pain sensation than men.
