Effect of Fiber Post-Resin Matrix Composition on Bond Strength of Post-Cement Interface

Figure 3

Measurement of the lateral surface area. Schematic drawing shows the post space radius used to calculate the lateral surface area (LS = lateral surface, R2 = coronal post space radius, R1 = apical post space radius, and H = slice thickness). Note that during push-out testing, each section was placed so that the apical side of each section is in direct contact with the push-out pin of the testing machine.
