Outline of Final Research Achievements

Pain is generally evaluated based on the patient's subjective expression. It would be useful for dentists to be able to score pain objectively. The purpose of this study was to evaluate intraoral pain objectively using functional near-infrared spectroscopy (fNIRS) and wavelet analysis of the ECG potential fluctuations.
When prefrontal cortical hemodynamics associated with experimental periodontal pain was measured using fNIRS, the decrease in blood flow in all areas of the prefrontal cortex was confirmed. There was a significant positive correlation between objective data obtained from wavelet analysis of the ECG potential fluctuations and subjective pain data from a visual analogue scale (VAS) for periodontal pain intensity.
