The purpose of the present study was to evaluate pulpal blood flow rate during Nd: YAG laser irradiation to yingxiang. Twelve volunteers at Tsurumi University School of Dental Medicine participated in this study. An Nd: YAG laser was irradiated to the left yingxiang for 30 sec at 100 mJ 15 pulses/sec (1.5W). Maxilla right canine pulpal blood flow rate was measured by a laser Doppler flowmeter during the irradiation, and the oxygen saturation was monitored throughout the irra diation. In all subjects, the pulpal blood flow rate increased statistically significantly during laser irradiation (p < 0.01), but the oxygen saturation was not affected. The maxilla right canine pulpal blood flow rate increased immediately after Nd: YAG laser irradiation to yingxiang. The results suggested that the pulpal blood flow rate was influenced immediately after the Nd: YAG laser was irradiated to the acupuncture point.
