Abstract：
One of the most important factors that determine the success of pulpectomy in primary teeth is the root canal filling material used. This systematic review is an update on the success rates of various materials used for obturation in primary teeth. An electronic search was carried out in the PubMed, Scopus, Web of Science, and Cochrane Library databases with the preset inclusion and exclusion criteria. Only randomized or quasi-randomized clinical and controlled trials with a minimum follow-up of 12 months were included for analysis. Nine articles were considered potentially eligible for inclusion in this review. All the included trials had zinc oxide-eugenol (ZOE) cement as a control group. The time span of the included trials extended from 12 to 30 months. Only 2 trials were at low risk of bias. Evidence to support the success rates of obturating materials used in primary teeth is scarce, which necessitates further highquality randomized controlled clinical trials with regard to this issue.
摘要：
决定乳牙牙髓切除术成功的最重要因素之一是所使用的根管填充材料。此系统评价是对用于乳牙闭塞的各种材料的成功率的更新。在PubMed中进行了电子搜索，Scopus,WebofScience,和符合预设纳入和排除标准的CochraneLibrary数据库。仅纳入最少随访12个月的随机或准随机临床和对照试验进行分析。九篇文章被认为有可能被纳入本评论。所有纳入的试验均以氧化锌丁香酚（ZOE）水泥作为对照组。纳入试验的时间跨度从12个月延长到30个月。只有2项试验存在低偏倚风险。支持用于乳牙的闭塞材料成功率的证据很少，这就需要进一步高质量的随机对照临床试验来解决这个问题。
