Laser Doppler flowmetry is a useful method for quantifying changes in microcirculation. The present study is designed to clarify if this method may also be used to assess the biocompatibility of dental materials. The experiments carried out on rats' incisors have shown that it is possible to record circulatory reactions occurring in the direct vicinity of the site of application. The reactive change in microcirculation in the apical part clearly differs from the local reaction at the site of application. A modification of the experimental set up allows the synchronous recording of blood flow in the apical and the incisal parts of the pulp. Calcium hydroxide is used to illustrate the local and the overall circulatory reaction of the dental pulp.
激光多普勒血流仪是一种用于量化微循环变化的有用方法。本研究旨在阐明该方法是否也可用于评估牙科材料的生物相容性。在大鼠切牙上进行的实验表明，有可能记录在应用部位紧邻区域发生的循环反应。根尖部微循环的反应性变化明显不同于应用部位的局部反应。对实验装置的改进允许同步记录牙髓根尖部和切端部的血流。使用氢氧化钙来说明牙髓的局部和整体循环反应。
