Abstract
Background: Resin cements are widely used for cementation of FRC posts, but their bond strength can be influenced by cement type and cementation technique. The aim of this study was to determine the effect of type of resin cement and cementation technique on the bond strength of fiber posts.
Methods: Forty five extracted mandibular premolars with a minimum root length of 14 mm were cut from 1 mm above the CEJ and root canal therapy was performed on them. Based on the type of cement, they were randomly divided into three groups: 1- Permacem, 2- Totalcem and 3- Breeze. Each group was divided into three subgroups based on cementation technique: 1- paper point, 2- lentulo and 3- tip. The push out test was carried out on 2-mm sections of cervical, medial and apical areas in the universal testing machine with a speed of 1 mm/min.
Results: The highest mean of bond strength among cements was in Breeze cement, but this finding was not statistically significant. In terms of different cementation techniques, the highest strength was found for lentulo technique. The bond strength showed no significant difference at different sections of root based on the type of cement and cementation technique.
Conclusion: Cement type has no significant effect on bond strength. The use of lentulo enhances bond strength significantly. No difference was observed in bond strength of different sections of the root in different cements. The greatest fracture mode was adhesive fracture between post and cement.
