Clin Oral Invest:氢氧化钙对根管充填质量的影响

2018-04-25 MedSci MedSci原创

本研究的目的是使用毛细管流量测定仪(CFP),评估根管内封氢氧化钙(CH)对根管充填的短期和长期封闭能力的影响。

本研究的目的是使用毛细管流量测定仪(CFP),评估根管内封氢氧化钙(CH)对根管充填的短期和长期封闭能力的影响。

为了验证该方法的可重复性,提供了五个标本。重复测量三次,并与非参数Friedman测试进行比较。四十五个腭根被随机分为三组。第1组:一步充填法。第2组:CH封药一周后冲洗取出CH并充填。第3组: CH封药一周后超声震荡取出并充填。充填后1周和6个月进行CFP测量。使用Wilcoxon符号秩检验,使用Kruskal-Wallis检验和组内比较随时间进行组间比较。显着性水平设定为0.05。

结果发现,在五个样本中,连续测量的最小值,平均流量和最大孔径之间没有差异,表明该方法的可重复性。在1周和6个月时,在3组之间没有检测到密封能力的差异,在1周和6个月之间也没有检测到每组之间的密封能力差异。

结论: CH封药不会显着影响根管充填的短期和长期封闭能力。
