The aim of this study was to evaluate the microleakage of 4 fiber post-luting systems using the computerized fluid filtration method.
Methods
60 extracted human mandibular permanent premolar teeth were used for the study. The teeth were instrumented with Hedstroem files up to size 60, post spaces were prepared and then Unicore fiber posts were cemented using 4 luting systems. Group1: Duolink, Group 2: Resinomer, Group 3: Fuji Plus, Group 4: Multilink Sprint, Group 5: Positive Control, and Group 6: Negative Control. The samples were stored in distilled water for 2 weeks and then microleakage was evaluated. Data were analyzed with 1 way-ANOVA and Dunett T3 tests (P<.05). Groups 2 and 3 significantly exhibited higher microleakage values than groups 1 and 4 (P<.05).
Results
Resin cements used with total etch-bonding systems demonstrated lower microleakage values than the other cements.
Conclusions
Reduction of steps in dentin conditioning of resin luting cements may have a promoting effect on microleakage.
