Abstract

Abstract: Objective: To study the effect of procyanidins (PA) on the bonding durability of fiber post. Methods: 36 premolars with single root canal were treated by root canal therapy. After post space preparation, the premolars were randomly divided into 4 groups: A: 6.5％PA+ non-aging B: 6.5％PA +aging, C: ethanol + non-aging D: ethanol + aging. Specimens of 1mm thick slices which were used to test the shear bond strength were taken from the neck, middle, and tip of the 7 fiber post specimens from each group. Stereomicroscope and SEM were used to count and observe the failure mode. The remaining 2 samples of each group were used to conduct indian ink dyeing. Results: The bonding strength of PA pretreatment group was higher than that of ethanol group (P＜0.05). The interaction between PA pretreatment and aging on bond strength was statistically significance (P＜0.05). The interaction between different parts of root canal and PA pretreatment on bond strength had no statistically significance (P＞0.05). The failure mode was mainly mixed damage. D group presented the most apparent microleakage. Conclusion: PA can improve the bond strength and durability of the neck, middle, and tip parts of the fiber post.

Key words: procyanidins, fiber post, bond strength, aging, microleakage
