Introduction:The objectives of obturating a root canal is to eradicate all avenues of leakage and to seal within the system any irritants that cannot be removed during cleaning and shaping .It is also important that the obturating material reinforces the remaining root ,because vertical root fractures in endodontically treated teeth is a common post endodontic treatment sequel. Various new obturating materials have been marketed to obturate the root canal three dimensionally as well as to prevent the post obturation fracture of the tooth. Aim-The purpose of this in vitro study was to evaluate the fracture resistance of endodontically treated teeth obturated with new obturating systems such as Realseal system, GuttaFlowobturation system, Microsealobturationsystem ,conventional lateral compaction technique. Method- Fifty extracted single rooted teeth that met the selection criteria were selected and sectioned at the cementoenamel junction. The root canals were instrumented using EasyRace files and irrigated with 0.5% sodium hypochlorite and saline. The teeth were randomly divided into 5 groups of 10 teeth each. Group 1 served as negative control and was not obturated. The other groups were obturated with Resilon cones and RealSeal sealer (group II) ,Guttaflow with single cone (group III),guttapercha and zinc oxide eugenol sealer (group IV) and Microseal system (groupV). The specimens were stored in 100 percent humidity.The specimens were prepared for loading to failure and an Instron universal testing machine that was caliberated to drive the spreader vertically into the root canal at a speed of 10 mm/min.
