Background: Vertical root fracture and crown root fracture are a major clinical issues that may occur due to excessive widening of canals, use of irrigants, and medicaments. It is one of the most frequent cause for the extraction of root-filled teeth. Therefore, in addition to complete sealing of the cavity, an intraorifice barrier could be placed to strengthen the remaining tooth structure.  Aim: The aim of the study is to assess the impact of two alternative intra-orifice barrier materials on the resistance of fracture of endodontically treated teeth. Materials and Methodology: 45 extracted single-rooted human mandibular premolars, decoronated to equal dimension, prepared to be obturated with gutta-percha. The placement of different intraorifice barrier materials, was done by removing coronal 3-mm of gutta percha, except for the control group. Based on the intraorifice barrier material used, the specimens were divided into three groups (n = 15). Group I: Control Group II: Resin modified GIC Group III: Composite Universal testing machine was used to record the fracture resistance of the specimens.  Results: Better resistance to fracture was seen with flowable nanohybrid composite and control group presented the least values.  Conclusion: An intraorifice barrier can be used for reinforcement of the teeth that have undergone endodontic therapy, making it a successful therapeutic approach.
