Abstract

Aim of the present study was to compare the fracture resistance of endodontically treated teeth restored using various root reinforcement methods.  Materials and Methods: In this study Fifty extracted human single rooted teeth were used as specimen. The samples were decoronated and working length was determined. Obturation was carried out by lateral condensation. Leaving 4mm of guttapercha apically rest was removed with the help of Gates Glidden drills. The specimens were divided into 5 groups with 10 each. Group -1 restored with glass fibre post luted with resin cement. Group-11 Ribbond fibre luted with resin cement. Group-III Restored with cast post and core luted with resin cement. Group-IV restored with glass fibre post luted with resin cement. Group-V Restored with light transmitting post.The samples were subjected to universal testing machine at angle of 45o to the long axis of the tooth at compressive loads of 0.5mm/min.  Results: Results were statistically analyzed under Anova and Tukey test.The study revealed results with Group 1 (800N) group 11(594N) GROUP III (308N) GROUP IV (898N) GROUP V (903N).the study revealed higher resistance to fracture with the prefabricated post systems when compared with the metal post systems. Conclusion: Prefabricated post systems can be used as an alternative to the traditional cast post and core systems.
