摘要： 目的: 研究Er:YAG激光桩道荡洗技术对纤维桩微渗漏的影响。方法: 选取大小形状相似的30颗单根管离体上前牙,经常规根管治疗后,根管上段2/3行桩道预备。按照荡洗技术随机平均分成3组:生理盐水组、2.5%次氯酸钠溶液组、Er:YAG激光联合2.5%次氯酸钠溶液组。纸尖干燥桩道并完成纤维桩粘接。截取离体牙釉牙骨质界至下方6 mm牙体作为检测试件,采用葡萄糖氧化酶-过氧化物酶法测量其微渗漏情况。结果: 生理盐水荡洗组的微渗漏为(0.941±0.096) mmol/L,2.5%次氯酸钠溶液荡洗组的微渗漏为(0.911±0.075) mmol/L,Er:YAG激光联合2.5%次氯酸钠荡洗组的微渗漏为(0.889±0.102) mmol/L。3种荡洗技术间的微渗漏程度比较差异有统计学意义(P<0.05)。结论: Er:YAG激光辅助荡洗桩道能够减少纤维桩微渗漏。

Abstract: Objective: To study the influence of Er:YAG laser-activated post space irrigation on fiber post microleakage. Methods: A total of 30 extracted upper incisors with similar size and shape were randomly divided in 3 groups. After　conventional root canal treatment and post space preparation, three kinds of irrigation (sodium chloride solution, 2.5% sodium hypochlorite, and Er:YAG laser with 2.5% sodium hypochlorite) were applied to the post space. After sticking fiber post with bond, the specimens were cut out 6 mm　from cement-enamel junction. The degree of microleakage was measured by Glucose oxidase-peroxidase (GOD-POD) method. Results: The microleakage　degrees of sodium chloride solution, 2.5% sodium hypochlorite, and Er:YAG laser with 2.5% sodium hypochlorite were (0.941±0.096) mmol/L, (0.911±0.075) mmol/L, and (0.889±0.102) mmol/L, respectively (P＜0.05). Conclusion: Er:YAG laser-activated post space irrigation can reduce the microleakage of fiber post.
