AIM: This in vitro study aimed to test the fracture resistance of 4 different posts used in the restoration of severely decayed primary incisors.
MATERIALS AND METHODS: 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 γ '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.
RESULTS: 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 (P>0.05).
CONCLUSION: Split-ended glass fiber posts seem to be a more appropriate option for full coverage restorations in primary incisors.
