- Primary Outcome Measures
Name Time Method Cerebral blood flow and saliva volume will be measured before the study begins. Saliva will be collected using a salivator and resting saliva volume will be measured. Next, the subjects will wear near-infrared spectroscopy (NIRS) and be irradiated with near-infrared radiation for 30 seconds to one minute at a time in eight blocks according to the irradiation manual. The subjects were irradiated with near-infrared light for 30 seconds to one minute at a time, according to the irradiation manual, in eight blocks. The rate of change in the signal at this time was measured by NIRS. As a control, we will measure the change in cerebral blood flow rate of the gingival massage in the same order and at the same time as the experimental group.
- Secondary Outcome Measures
Name Time Method ear-infrared irradiation was continued for one week at home after brushing the teeth at night according to the irradiation manual, and saliva was collected again after one week to compare saliva levels.
