Abstract : The effect of diameter and surface treatment on prefabricated zirconium dioxide (diameter 1.4mm and 1.7mm) and glass ber-reinforced (diameter 1.3mm and 1.6mm) endodontic posts were studied. The Zr posts were divided into groups A, B, and C, based on the surface treatment. Group A, the control group was given no surface treatment, group B was airborne particle abraded using 110m alumina and group C roughened with a coarse grit diamond bur. FRC-posts without any surface treatment constituted Group D. The samples were tested for fracture resistance in an Instron Universal Testing Machine. One way ANOVA, small sample student t test, & Pearson correlation coefficient were the statistical tools employed to analyze the observations. Zirconium dioxide posts showed statistically signicant higher fracture resistance when compared to glass FRC-posts. Surface treating the Zr posts with airborne particle abrasion further signicantly improved the fracture resistanc
