[Evaluation of the coronal leakage of fiber posts using different adhesive approaches].


PMID 21779732

Abstract

To test and compare the marginal leakage of radicular dentin cemented with three resin cements. Nine extracted maxillary incisors after endodontically treated were divided into 3 groups(n=3).Fiber posts were inserted using three resin cements: One-Step Plus/DuoLink (OD),ParaCore Automix (PA) and RelyXTM Unicem(RU).All teeth were subjected to thermocycling for 5000 cycles. All teeth were stained in 0.1% basic fuchsin for 24h and then longitudinally sectioned into four parts.Coronal leakage was evaluated. SAS 6.0 software package was used for Kruskal-Wallis test. Different resin cements significantly affected the coronal leakage of fiber posts(P<0.001). The system RU, which represents a new simplified self-adhesive protocol, performs the best sealing capacity.
