摘要： 目的:根管内纤维桩的粘结有一定的不确定性,特别是在根尖区。本研究对纤维桩在粘结过程中,分别在使用手动模式和声波模式下,对根管内壁进行酸蚀冲洗粘结后,评价其推出强度(push-out bond strength, PBS)和纳米渗透(nanoleakage, NL)的情况。方法:经过完善根管治疗的前磨牙,随机分为2组,手工模式组和声波模式组。纤维桩粘固后在0.5 mm/min的加载速度下测试推出强度。在硝酸银浸泡后的扫描型电子显微镜下评价纳米渗漏。数据采用方差分析和T检验分析。结果:两组比较,声波模式组推出强度增加,纳米渗漏在根中和根尖1/3有所下降(P<0.05)。结论:应用声波辅助涂抹可以有效提高纤维桩的粘结效果。

Abstract: Objective: To evaluate the effect of the application mode of etch-and-rinse adhesives on the push-out bond strength (PBS) and nanoleakage (NL) of fiber posts in the root canal. Methods: The roots of human premolars were endodontically prepared and divided into 2 groups according to the application mode (manual or sonic). The posts were cemented and the PBS tested at 0.5 mm/min. The NL was evaluated by scanning electron microscopy after the immersion of specimens in 50% silver nitrate. Root third was also considered in the statistical evaluation. Data were analyzed by t and chi-square tests. Results: Under sonic application, the PBS increased, whereas NL decreased significantly in the middle and apical thirds (P<0.05). Conclusion: The application of simplified adhesives by sonic mode in the root canal is a feasible tool to increase the fiber post bond to root canals.

Key words: Fiber posts, Sonic application, Push-out bond strength, Nanoleakage
