The pain-pressure threshold in human tissues such as muscles may be affected by the anatomic location of the recording site and the rate of applied pressure. However, it is uncertain how these variables affect the pain-pressure threshold in healthy oral tissues. In 10 subjects, a custom-made algometer was used to apply pressure at a constant rate to 12 sites on the attached gingivae apical to teeth 11 to 16 and 41 to 46. The pain-pressure threshold was measured at three different rates of applied pressure at weekly intervals for 4 weeks. The pain-pressure threshold was consistently higher at maxillary recording sites. There were, however, no differences in the pain-pressure threshold at different recording sites along the tooth row in the maxilla or mandible. The pain-pressure threshold measurements were consistent between recording sessions. The pain-pressure threshold was affected by the rate of pressure application and appeared to increase linearly with increasing rate. This suggests that the pain-pressure threshold may be measured consistently in attached human gingivae. When measurement of deep sensation in the oral mucosa is planned, the location of the recording site and the rate of applied pressure should be verified.
人体组织（如肌肉）的痛觉-压力阈值可能会受到记录部位的解剖位置和施加压力的速率的影响。然而，这些变量如何影响健康口腔组织的痛觉-压力阈值尚不确定。在10名受试者中，使用定制的痛觉计以恒定速率对牙齿11至16以及41至46根尖附着龈上的12个部位施加压力。在4周内，每周以三种不同的施加压力速率测量痛觉-压力阈值。上颌记录部位的痛觉-压力阈值始终较高。然而，在上颌或下颌沿牙列的不同记录部位，痛觉-压力阈值并无差异。不同记录时段的痛觉-压力阈值测量结果一致。痛觉-压力阈值受压力施加速率的影响，且似乎随速率增加呈线性增加。这表明在附着的人体牙龈中可以一致地测量痛觉-压力阈值。当计划测量口腔黏膜的深部感觉时，应验证记录部位的位置和施加压力的速率。
