The purpose of this study was to investigate the effects of mechanical load on blood flow in the palatal mucosa. In five healthy dentate subjects (mean age 26.4 yrs), the blood flow in palatal mucosa was measured using the laser Doppler flowmeter. A 400 gf load was applied through a 4mm-diameter probe in the posterio-lateral aspect and the central rugae area of the palate for 40 s. The blood flowmetry in the posterio-lateral site of the palate was also performed for loading intervals of 10, 20 and 30 s, and for the load intensity of 100, 200 and 400 gf, respectively. The results obtained were as follows:<BR>1. The effect of load on blood flow varied with the site of force application in the palate. A reactive hyperemia was almost always observed after the removal of load in the posterio-lateral region. However, no reaction or unclear reactive hyperemia was noted at the anterior site.<BR>2. There was a tendency that an increase in the loading interval extended the recovery period to the baseline. The reduction in blood flow during the load and its increase after the load removal tended to be constant regardless of the loading interval.<BR>3. An increase in load intensity resulted in the reduction of blood flow during loading and the extension of recovery period. On the other hand, the degree of increase in blood flow after the load removal was not affected by the change of load intensity.<BR>4. The relationships between the loading interval and the recovery period, between the load intensity and the recovery period, and between the load intensity and the reduction in blood flow during the load were considered to be useful parameters for evaluating the characteristics of the palatal mucosa.
