The retentive strength of three zinc oxide-eugenol cements and three noneugenol-containing zine 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.
