激光多普勒血流仪（LDF）以前曾用于测量人类牙齿中的血流。本研究旨在探讨LDF在年轻恒牙牙髓活力评价中的临床应用。33颗牙髓坏死的门牙的流量测量值明显低于未受伤的对照牙（比率0.13±0.025）。心跳同步振荡和低频波动存在于记录信号从正常的牙齿是不存在的33个非活髓牙的29。在16个脱位牙齿不确定牙髓诊断，正常的LDF值最初获得保持正常的整个随访期间。在这一时期结束时（3-120周），牙髓活力间接证实使用传统的临床观察，包括恢复响应电动牙髓测试仪。因此，LDF可以用来确定牙髓活力在受伤的牙齿在一个阶段时，传统的临床研究结果是不确定的。
Laser Doppler flowmetry (LDF) has previously been used to measure blood flow in human teeth. In the present studs the clinical application of LDF in assessing pulpal vitality in young, injured, permanent teeth was investigated. Flow-metric values determined in 33 incisors with necrotic pulps were distinctly lower than those in non-injured control teeth (ratio 0.13±0.025). Heart beat synchronous oscillations and low frequency fluctuations present in the recording signal from normal teeth were absent in 29 of the 33 non-vital teeth. In 16 luxated teeth with uncertain pulpal diagnosis, normal LDF values obtained initially remained normal throughout the follow-up period. At the end of this period (3-120 weeks), pulpal vitality was confirmed indirectly using traditional clinical observations, including regained response to an electric pulp tester. Thus, LDF can be used to determine pulpal vitality in injured teeth at a stage when conventional clinical findings are inconclusive.
