Abstract

Introduction: Prefabricated endodontic post is one of the most effective factors to increase retention in severely destroyed teeth restorations. The retention is related to the post and cement. The aim of this study was to compare the retentive capacity of two prefabricated endodontic posts comented with two different luting cements. Materials &amp; Methods: In this parallel experimental in vitro study, 32 intact similar single root premolars were divided into two equal groups. The teeth were cut at CEJ and received endodontic treatment. The post spaces were prepared with pisoreamer drills. In the first group, Dentatus posts were cemented with zinc phosphate in eight teeth and the remainder was cemented with glass ionomer. In the other group para posts were cemented in two subgroups the same as Dentatus posts. After mounting all specimens in acrylic resin blocks the retention of each post was measured with Instron testing machine and the data were analyzed with student t-test (∞=0.05). Results: The mean retention value of the para post group was higher than the other one (P<0.001). But there was no significant difference between two cements (P=0.11). The retention values for zinc phosphate cement was higher in para post group (P<0.001) but in Dentatus group there was no difference between subgroups (P=0.64). Conclusion: The retention capacity was higher with para post in comparison with Dentatus. Zinc phosphate showed higher retention with para post but there was no difference between zinc phosphate and glass ionomer cement in retention of Dentatust post.
