Abstract	Abstract Background: Fiber-reinforced composite (FRC) posts have been successfully used in the clinic since years ago. Adhered by the adhesive boundary which has epoxy matrix and the resin. cement. The root canal and the surrounding anatomy is variable regionally often giving rise to a bond failure. strength discrepancies. Objective: This study was undertaken to determine the "regional This section features a comparison of the push-out bond strength (POBS) of FRC with that of radicular dentin. Sand blasted, 37% phosphoric acid etched and silane treated posts. Across the 3rd root couplets and over the center root. Materials and Methods: A total of 40 extracted human maxillary MCIs were endodontically treated and mounted on a model. Groups were divided into four groups (n=10): Control (Group A), Sandblasting (Group B), Acid etching (Group C), and Silane Coupling Agent (Group D). Dual-cure resin cement was used to luted posts with. Roots were sectioned. These were cut into 4 mm slices, the coronal and middle 3rd. POBS was measured using a Universal testing machine (1 mm/min). Analysis of variance was used to analyze the data. Tukey HSD (p < 0.05). Results: The sandblasting conditions leaded to the highest values in group B. It has a bond strength of 369.21MPa in the coronal area and 400.16MPa in the middle area. A the largest mean scores. The mean scores of the middle third were observed as "Regional Paradox" for group B. The bond strength of the coronal third was significantly less than the other regions (p < 0.05). Group C Performed not as well, and gave values below the control in the coronal region. Conclusion: The best chairside surface treatment is sand blasting. It’s The product overcomes the need for formal micro mechanic interlocking due to its ability to form solid micromechanical interlocking. Catering to the traditional anatomical limitations of the deeper root canal, offering superior surface interactions. Overcoming the surface interactions within traditional anatomical limitations of the deeper root canal. The middle third remains as it is.
