Two groups of volunteers were examined with regard to the threshold level of a maxillary incisor for axialIy applied forces. One group showed an advanced periodontilis around the examined tooth, while the other group presented no clinical periodontal pathology. The ascending method of limits was used to determine the psychophysical threshold level. The relationship between the threshold level and the force application rate appeared to be linear on a lin‐log and a log‐log display. Higher rates gave lower threshold levels. For equal rales, the threshold level of the periodontilis group was significantly higher than for the control group. The results indicate that the periodontal mechanoreceptors are sensitive to the rate of force application, whatever the periodontal condition. Advanced periodontitis. however, clearly impairs the tactile function of the tooth supporting tissues.
