This in vitro study aimed to test the fracture resistance of 4 different posts used in the restoration of severely decayed
Fifty primary incisors were selected for this study and sectioned 1 mm above the CEJ.
After filing and irrigation of the root canal space, the canals were obturated with Metapex and 3 mm of post space was prepared inside
the canals. Intact glass fiber posts, split-ended glass fiber posts, composite resin posts, and orthodontic 'gamma' wire posts were
used as intracanal posts and the final composite resin restoration was placed using a paediatric strip crown. After thermocycling of the
specimens, the fracture resistance was measured using a universal testing machine.
The mean fracture resistance of split-
ended glass fiber posts was higher than the other groups, however, there was no significant difference between any of the groups
Split-ended glass fiber posts seem to be a more appropriate option for full coverage restorations in
