The sealing efficacy of temporary endodontic filling materials was tested in vivo. The following materials were studied: Cavit, Caviton, gutta-percha, three types of zinc phosphate cement, and zinc oxide and eugenol. All the materials were tested in the access cavity of the same anterior tooth in ten different patients for a minimum of 1 week. Seepage was determined bacteriologically by culturing a cotton pellet which was sealed into the access cavity. On the basis of the quantity of microorganisms grown anaerobically, differentiation was made between no leakage, minor leakage, and gross leakage. Findings with Cavit and Caviton are essentially the same and show no or minor leakage in the vast majority of tests. Gutta-percha showed gross leakage in six out of eight tests. Phosphate cements showed no leakage in more than two thirds of the tests.
对临时牙髓充填材料的封闭效果进行了体内测试。研究了以下材料：Cavit、Caviton、牙胶、三种磷酸锌水门汀以及氧化锌丁香酚。所有材料在10名不同患者的同一颗前牙的髓腔入口中进行了至少1周的测试。通过培养密封在髓腔入口中的棉球进行细菌学渗漏测定。根据厌氧生长的微生物数量，区分无渗漏、轻微渗漏和严重渗漏。Cavit和Caviton的测试结果基本相同，在绝大多数测试中无渗漏或仅有轻微渗漏。牙胶在8次测试中有6次出现严重渗漏。磷酸锌水门汀在超过三分之二的测试中无渗漏。
