Laser-Doppler-flowmetry enables us to assess microcirculatory changes in the tooth pulp. This method can also be used for testing the histocompatibility of dental materials. The acid components of Tenet and Ketac-Cem are examined for tissue tolerance. This is done by assessing the incisal and apical changes in pulpal microcirculation. The phosphoric acid of Tenet causes an almost complete collapse of the incisal microcirculation just a short time after its application. The tartrate of Ketac-Cem causes long-lasting hyperaemia, whereas the acryl-maleinate-copolymer has no discernible effects.
激光多普勒血流仪使我们能够评估牙髓中的微循环变化。该方法还可用于测试牙科材料的组织相容性。对Tenet和Ketac-Cem的酸性成分进行组织耐受性检查。这是通过评估牙髓微循环在切端和根尖的变化来完成的。Tenet的磷酸在应用后短时间内会导致切端微循环几乎完全崩溃。Ketac-Cem的酒石酸盐会导致长期充血，而丙烯酸-马来酸酯共聚物则没有明显影响。
