Comparison between two coating techniques of glass fiber posts treated with hydrogen peroxide 35% on its stability in root canals after cementing using resin cement (In vitro comparative study)

AUTHOR(S): Abdel Ghani Alsahhar and Bassam Alnajjar
ABSTRACT:
Aim of the Study: This research aims to compare two techniques of coating glass fiber posts to define the best technique that achieves the higher tensile resistance after cementing with dual-cure resin cement into prepared human teeth root canals.
Materials and Methods: The sample of this research consisted of 20 extracted human lower premolars which their crowns were cut horizontally 2 mm above the cementoenamel junction, then the root canals were treated endodontically with suitable instruments and divided into 2 groups according to techniques used in coating the glass fiber posts luted into them: Group A: 10 fiber posts were coated with silane before cementing. Group B: 10 fiber posts were coated with unfilled resin before cementing. Each specimen was secured in a universal tensile-test machine. An increasing tensile force was applied on the free part of the fiber post vertically at a crosshead speed of 1 mm/min along with the long axis of the tooth until adhesive failure occurred.
Results: The results of the tensile test indicated that there is no statistically significant differences in the average tensile resistance between A and B groups.
Conclusions: There was no significant difference in stability strength between the technique of using silane and the technique of using unfilled resin to coat the glass fiber post before cementing with resin cement.
