The retentive strength of three zinc oxide-eugenol cements and three noneugenol-containing zinc oxide cements and the effect of the addition of petrolatum on retention were tested. The addition of petrolatum was found to affect retention of the cements significantly. Retention strengths varied from 1.6 kg to 40.0 kg. Of the Class 1, Type 2, systems tested, noneugenol cements had higher retentive values than did the eugenol-containing cements.
测试了三种氧化锌丁香酚水门汀和三种不含丁香酚的氧化锌水门汀的固位强度，以及添加凡士林对固位的影响。结果发现，添加凡士林对水门汀的固位有显著影响。固位强度在1.6千克至40.0千克之间。在所测试的1类2型体系中，不含丁香酚的水门汀比含丁香酚的水门汀具有更高的固位值。
