Objective.
To evaluate the influence of 3 different post-resin matrix systems cemented with dual-cure resin cement in simulated root canals made of PMMA acrylic sheet.
Methods.
3 types of fiber posts (n = 60) with different resin matrixes divided into 3 groups: group 1 cross-linked FRC Postec Plus post (n = 20), group 2 cross-linked Rely X post (n = 20), and group 3 Interpenetrated IPN Everstick post (n = 20).
All posts were cemented using Multilink Automix dual-cure cement.
Posts were cemented into acrylic blocks in order to purely test the strength of cement-post interface.
After one week storage at 37°C, two sections of 1 mm thickness from middle-third were subjected to micro-push-out test at crosshead speed 0.5 mm/min.
Results.
The data were analyzed using one-way analysis of variance (ANOVA).
The variable fiber post-matrix system was found to significantly affect the push-out bond strength (p<0.001).
Group 2 exhibited that the highest mean push-out bond strength was (5.36 + 2.3 MPa), and group 3 showed the lowest mean push-out (0.41 + 0.4 MPa).
There was significant difference among the groups regarding the failure mode as chi-square test revealed (p<0.001).
Conclusion.
Prefabricated cross-linked posts with epoxy-based matrix demonstrated higher bond strength than prefabricated cross-linked posts with Bis-GMA-based matrix and posts with semi-IPN matrix when luted with dimethacrylate-based dual-cured resin cement.
