Objectives: The purpose of this in vitro study was to evaluate the fracture resistance of endodontically treated teeth restored by glass fiber post and carbon fiber post systems.

Materials and methods: About 40 maxillary canines with anatomically similar root segments were taken and then decoronated at the cementoenamel junction. After establishing the working length 1 mm short of the apex, the canal was prepared by the Crown Down technique using rotary protaper followed by obturation. After 24 hours, post space preparation was done using a Peeso reamer. All the specimens were then divided into two groups (group I: Glass fiber post; group II: Carbon post). The posts were then cemented into the tooth using a resin sealer, and acrylic resin cylinders were obtained using cylindrical molds. Specimens were subjected to increasing compressive load (N) until fracture.

Results: There were statistically significant differences observed between the two groups, and it indicated that the glass posts have better fracture resistance capacity.

Conclusion: Within the limitation of this study, it is concluded that the glass fiber posts have better fracture resistance as compared with carbon posts.
