To Compare The Effect Of Different Intraorifice Barriers On The Fracture Resistance Of Endodontically Treated Roots Obturated With Gutta Percha: An In Vitro Study

Aim: ResinGuttaPercha and AH Plus sealer. Objective: 1.To evaluate fractur 2.To evaluate fracture resistance of Cention N as intraorifice barrier. 3.To evaluate fracture resistance of RMGIC as intraorifice barrier. Materials and Methods: and prepared and obturated with gutta was removed and filled with different materials, except for control specimens. The specimens (40) were divided into four groups ( n = 10) on the basis of the intraorifice barrier material used. Group 1: Ever X Pos resistance of the specimens was tested. Results: following manner: Ever X Posteri Conclusions: endodontically treated teeth. To compare the effect of different intraorifice barrier materials Ever X Posterior , Cention N, -Modified Glass Ionomer Cement (RMGIC) on the fracture resistance of roots obturated with e resistance of Ever X Posterior as intraorifice barrier. Forty mandibular premolars were decoronated to a standardized length, -percha and AH Plus sealer. The coronal 3 terior, Group 2: RMGIC, Group 3: Cention N, Group 4: No barrier (control). Fracture The mean force required for vertical fracture to occur in all 4 groups can be arranged in or >Cention N > RMGIC> Control. Ever X Posterior and Cention N significantly increase the fracture resistance of -mm gutta-percha
