Abstract

Introduction: The most common failure of tooth color posts is retention failure of posts. The aim of this study was to evaluate the effect of different surface treatments on the BOND STRENGTH of quartz fibere posts.Materials & Methods: In this experimental in vitro study, 70 mandibular single root canal premolar teeth that had no decay or crack, were selected and then endodontically treated. Post space preparation was made 9 mm long. 70 quartz fiber reinforced composite (FRC) posts were randomly divided into five groups for applying different surface treatments: Air abrasion, 24% Hydrogen peroxide, 21% sodium ethoxide, POTASSIUM PERMANGANATE 20%, no treatment (control). Then, a single layer of silane was applied to post surface of half of the specimens in each group. Next, the specimens were submitted to the pull out test. The failure mode was determined by stereomicroscope and SEM. The statistical analysis was performed using Two-Way ANOVA and Tukey’s test (α=0.05).Results: Only BOND STRENGTH of POTASSIUM PERMANGANATE group was significantly greater than those obtained with other groups (P<0.05). Use of silane decreased the BOND STRENGTH significantly (P<0.05). Assessment of failure mode showed as the BOND STRENGTH increased, the mixed failure mode increased. SEM evaluation revealed that application of air abrasion and POTASSIUM PERMANGANATE damaged the quartz fibers.Conclusion: Application of POTASSIUM PERMANGANATE increased the BOND STRENGTH and application of silane decreased BOND STRENGTH significantly. Application of POTASSIUM PERMANGANATE and air abrasion damaged quartz fibers.
