摘要: 目的:研究原花青素(procyanidins,PA)对纤维桩粘接耐久性的影响。方法:经根管治疗的36颗单根管前磨牙,桩道预备后随机分为4组(n=9)组,A组:6.5%PA +不老化,B组:6.5%PA +老化,C组:乙醇+不老化,D组:乙醇+老化。每组随机抽取7个样本从纤维桩的根颈、中、尖三分之一切取1 mm厚试件检测剪切粘接强度,统计并观察断裂模式。每组另2个样本进行印度墨水染色。结果:PA预处理组粘接强度高于乙醇组,差异有统计学意义(P<0.05);PA预处理和老化的交互作用对粘接强度的影响有统计学意义(P<0.05);根管不同部位和PA预处理的交互作用对粘接强度的影响无统计学意义(P>0.05)。各组断裂模式以混合破坏为主。D组微渗漏最明显。结论:PA可以提高纤维桩根颈、中、尖的即刻和老化后的粘接强度。

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.
