次氯酸钠去蛋白化对牙釉质抗剪切强度影响的Meta分析

Influence of deproteinization of sodium hypochlorite on shear bond strength of enamel: a Meta-analysis

目的对次氯酸钠增加牙釉质抗剪切强度的有效性进行Meta分析。方法计算机检索The Cochrane Library、Pub Med、CBM、CNKI、万方数据库、VIP数据库,检索时间均为建库至2017年9月30日。搜集有关次氯酸钠使牙釉质表面去蛋白化从而影响其抗剪切强度的相关研究。由两位研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后,采用RevMan5.3软件进行统计分析,Stata 12.0对发表偏倚进行分析。结果共纳入10个研究,包括处理组和对照组牙齿各179颗。Meta分析结果显示:连续性变量合并MD为3.86,95%CI为3.06~4.66。结论次氯酸钠处理牙面可以有效提高牙釉质的抗剪切强度。

Objective To evaluate the effectiveness of sodium hypochlorite in heightening the shear bond strength of enamel by Meta- analysis. Methods The Cochrane Library, PubMed, CBM, CNKI, WanFang Data, VIP databases from inception to September 30th, 2017, were searched to collect relative studies on the influence of deproteinization of sodium hypochlorite on shear bond strength of en- amel. Two reviewers independently screened the search results, extracted data and assessed the risk of bias of included studies. Then Meta-analysis was performed using RevMan5.3 software,while Stata 12.0 was used to valuate publication bias. Results A total of 10 studies were included, involving 179 teeth in treated and control groups respectively. The result of Meta-analysis showed that the pooled-MD and 95%CI for continuous variations were 3.86 and 3.06-4.66 respectively. Conclusion Treatment of tooth surface with so- dium hypochlorite can significantly improve the shear strength of enamel.
