To investigate the effect of calcium hydroxide intracanal medicament on the push-out bond strength of resin-based and calcium silicate-based endodontic sealers.
A comprehensive search of was conducted for all relevant in-vitro studies. All randomized controlled in-vitro studies that evaluated the effect of calcium hydroxide on the push-out bond strength of resin-based or calcium silicate-based endodontic sealers were assessed. The variables of interest were extracted, and the risk of the included studies was evaluated. The standardized mean difference was calculated and the significance level was set at p value <0.05.
A total of 26 studies were eligible for analysis. There were 45 independent comparison groups and 1009 recruited teeth. The pooled data showed no significant difference in push-out bond strength between calcium hydroxide and control group in the resin-based group (SMD = 0.03; 95% CI = -0.55, 0.60; p = 0.93), and calcium silicate-based group (SMD = 0.02; 95% CI = -0.31, 0.35; p = 0.90). Most of the studies (21 out of 26) were at medium risk of bias and five studies showed a low risk of bias.
The available evidence suggests that calcium hydroxide used as intracanal medication does not influence the push-out bond strength of the resin- and calcium silicate-based endodontic sealers.
The results of this meta-analysis suggest that calcium hydroxide used as intracanal medication does not influence the push-out bond strength of resin-based and calcium silicate-based endodontic sealers.
研究氢氧化钙根管内封药对树脂基和硅酸钙基根管封闭剂的推出强度的影响。
系统检索所有相关的体外研究。评估了所有评价氢氧化钙对树脂基或硅酸钙基根管封闭剂推出强度影响的随机对照体外研究。提取感兴趣的变量，并评估纳入研究的风险。计算标准化均数差，并将显著性水平设置为 p 值<0.05。
共有 26 项研究符合分析条件。共有 45 个独立比较组和 1009 颗被招募的牙齿。汇总数据显示，在树脂基组（SMD=0.03；95%CI=-0.55，0.60；p=0.93）和硅酸钙基组（SMD=0.02；95%CI=-0.31，0.35；p=0.90）中，氢氧化钙组与对照组的推出强度无显著差异。大多数研究（26 项研究中的 21 项）存在中度偏倚风险，5 项研究显示低偏倚风险。
现有证据表明，作为根管内封药的氢氧化钙不会影响树脂基和硅酸钙基根管封闭剂的推出强度。
这项荟萃分析的结果表明，作为根管内封药的氢氧化钙不会影响树脂基和硅酸钙基根管封闭剂的推出强度。
