With the aid of laser-Doppler-flowmetry we are able to determine changes in the microcirculation of the tooth pulp. This method can also be used for testing the histocompatibility of dental materials. The zinkoxiphosphate cement Tenet and the glass ionomer cement Ketac-Cem are examined for tissue tolerance. This is done by determining the incisal and apical changes in pulpal microcirculation. Tenet has almost no discernible effect on pulpal microcirculation. Ketac-Cem causes a longlasting hyperaemia in half of the cases which seems to depend on the depth of cavity preparation.
借助激光多普勒血流仪，我们能够测定牙髓微循环的变化。该方法还可用于测试牙科材料的组织相容性。对磷酸锌水门汀Tenet和玻璃离子水门汀Ketac-Cem进行组织耐受性检测。这通过测定牙髓微循环在切端和根尖的变化来完成。Tenet对牙髓微循环几乎没有明显影响。Ketac-Cem在半数病例中会引起持久的充血，这似乎取决于窝洞制备的深度。
