Aim: Comparative evaluation of the fracture resistance of endodontically treated maxillary central incisors restored with prefabricated glass fiber posts and experimental dentin posts prepared human root dentin.
Materials & method: Thirty six extracted human Maxillary central incisors were divided in to three groups. In Group-I (Control group) 12 samples, Group-II (Glass fiber posts)12 samples, Group-III (Dentin posts) 12 samples. Twenty four teeth were restored with Glass fiber posts and Solid dentin posts and numbered as Group-II and Group- III respectively while Group-I acted as a control, without any posts only core build up. Teeth were loaded at 130º angle to their long axes after core build up and the failure load were recorded.
Result: Statistical analysis showed that Group III (Dentin posts) (120.9 ± 1.447) and Group II (Glass Fibre posts) (118.6±1.437) the mean failure load value was significantly higher than Group I (Control group) (59.71±2.684). There had no statistically significant difference between group II (Glass fiber posts) and group III (Dentin posts) (Table-1) (Graph-1).
Conclusion: Teeth restored with the dentin posts exhibited marginally better fracture resistance than those restored with glass fiber posts.

Key words: Glass fiber posts, Dentin posts, fracture resistance.
