The aims of this study were to systematically review the literature and statistically analyze the effectiveness of different cleaning methods on the bond strength of resin cement to zirconia in short- and long-term aging conditions.
DATA/SOURCES: The literature was electronically searched in PubMed (MEDLINE), EMBASE, Wiley, Scopus, and Open Access Theses and Dissertations databases to select relevant articles that evaluated the bond strength between contaminated zirconia and resin cements. A manual search was performed by scanning the reference lists of included studies.
All articles were published online before April 2022 and in English. Meta-analyses were conducted using random effects models to calculate standardized mean differences (SMD) between uncontaminated zirconia and various cleaning methods in two aging conditions (short- and long-term). Statistical heterogeneity was assessed using I-square statistics. The risk of bias of all included studies was assessed. All statistical analyses were conducted using STATA (StataCorp, College Station, Texas).
Of the 1181 studies, 25 studies met the inclusion criteria for qualitative analyses. In short-term aging condition, cleaning contaminated zirconia with water, alcohol, or acid etching reported significantly lower bond strength than uncontaminated zirconia. For long-term aging condition, cleaning contaminated zirconia with water, cleaning agents, alcohol, or acid etching reported significantly lower bond strength than uncontaminated zirconia. Alumina air-abrasion or cleaning with sodium hypochlorite were comparable to uncontaminated zirconia for both short- and long-term aging conditions.
This meta-analysis appeared to indicate that the cleaning methods of contaminated zirconia restoration have an effect on zirconia bonding.
本研究旨在系统地回顾文献，并对不同清洁方法在短期和长期老化条件下对树脂水泥与氧化锆粘结强度的有效性进行统计学分析。
数据/来源：通过电子方式在 PubMed（MEDLINE）、EMBASE、Wiley、Scopus 和开放获取论文和学位数据库中搜索文献，以选择评估污染氧化锆与树脂水泥之间粘结强度的相关文章。通过扫描纳入研究的参考文献列表进行手动搜索。
所有文章均在 2022 年 4 月之前在线发表，且为英文。使用随机效应模型进行荟萃分析，以计算两种老化条件（短期和长期）下未污染氧化锆和各种清洁方法之间的标准化均数差异（SMD）。使用 I 平方统计评估统计异质性。评估所有纳入研究的偏倚风险。所有统计分析均使用 STATA（StataCorp，德克萨斯州大学城）进行。
在 1181 项研究中，有 25 项研究符合定性分析的纳入标准。在短期老化条件下，用清水、酒精或酸蚀清洁污染的氧化锆报告的粘结强度明显低于未污染的氧化锆。对于长期老化条件，用清水、清洁剂、酒精或酸蚀清洁污染的氧化锆报告的粘结强度明显低于未污染的氧化锆。对于短期和长期老化条件，氧化铝空气喷砂或用次氯酸钠清洁与未污染的氧化锆相当。
这项荟萃分析似乎表明，污染氧化锆修复体的清洁方法对氧化锆粘结有影响。
