Abstract

Although the palpating procedure is convenient to evaluate pain status at the muscle site and TMJ, the results are not necessarily objective. By means of utilizing a small thin force sensing film attached to the finger tip, quantitative measurement was enabled during palpation. This study was composed of 2 experiments. The first experiment, involving 20 dentists, was conducted to understand the relationship between pressure pain threshold (PPT) and pressure increment rate (PIR) during palpation. PPT was associated to PIR when utilizing a plunger pressure device (r=0.82). However, there was little correlation between the PPT and PIR on palpation (r=0.33). This specific PPT-PIR relation might be caused by the difference in force direction between the palpation and the plunger device. In the second experiment, 22 dental students were tested. They were given instructions to apply 1.0kgf to the mid-point of masseter region of the test subject. With the aid of actual pressure feedback training, the mean values of finger pressing force before training, right after the training, and 1 week following the training were an average of 0.64, 1.25, and 1.58kgf, respectively. Since the difference between the target and actual value was reduced in the post training measurement, the developed 2-channel pressure measuring system was found to help regulate constant force during palpation and could be expected to be a useful educational tool for palpation.
