Methods: 50 primary incisors were selected for this study and all the teeth were sectioned 1 mm above the CEJ. After filing and irrigation of root canal space, the canals were obturated with metapex and 3 mm of post space was prepared inside the canals. Intact glass fiber post, split-ended glass fiber post, composite resin post, and orthodontic wire ã post were used as intracanal posts. The final composite resin restoration was done by using pedodontic strip crown. After thermocycling the specimens, the fracture resistance was measured using a universal testing machine.
Results: The mean fracture resistance of split-ended glass fiber posts was higher than that of other posts; however, there was no significant difference between any of the groups (P>0.05).
Conclusions: Split-ended glass fiber posts seem to be a more appropriate option for full-coverage restorations in primary incisors.
