The lactic acid jet test has been proposed for incorporation in international standards for dental cements, since results correlate well with in vivo erosion. In the literature, jet test results have been reported on only six glass ionomer cements. This study examines three types of glass ionomer, restorative, luting and metal reinforced, twenty materials from six manufacturers. A wide range of erosion rates was found particularly for restorative cements. The hypotheses put forward by previous workers to explain differences in erosion rates found on their limited range of glass ionomers do not apply to the wider range that we tested.
乳酸喷射试验已被提议纳入牙科水门汀的国际标准中，因为其结果与体内侵蚀情况具有良好的相关性。在文献中，仅报道了六种玻璃离子水门汀的喷射试验结果。本研究考察了三种类型的玻璃离子水门汀，即修复用、粘结用和金属增强型，共来自六个制造商的二十种材料。结果发现侵蚀速率范围很广，尤其是修复用水门汀。先前研究人员针对其测试的有限种类玻璃离子水门汀所提出的、用于解释侵蚀速率差异的假设，并不适用于我们所测试的更广泛的材料种类。
