| Research Abstract |
In the present study, the applicability of a tissue blood oxygenation monitor based on Kashima's report to human lip was examined. The amount of oxy-hemoglobin, the amount of deoxy-hemoglobin, total amount of hemoglobin (THb) and oxygen saturation levels (StO2) in human lower lips were measured using the tissue blood oxygenation monitor. Deep breath evoked a transient decrease of StO2 both in lip, and the change in StO2 was not synchronous either with BF or THb. The results indicated that the device used in this study reflected tissue oxygenation levels. The purpose of this study was to examine the relation between root formation and the pulpal blood flow (PBF) in human young permanent teeth using laser Doppler flowmeter. The mean PBF signals tended to decrease with the progress of the root formation. The decrease was, however, statistically not significant. PBF measurement was considered to be applicable to assess root formation in young permanent teeth.
