Isolation with cotton rolls does not always provide as complete isolation as rubber dam, especially in procedures where absolute moisture control is critical. Therefore, this review aims to summarize and analyze previous studies evaluating the retention and marginal integrity of pit & fissure sealant using rubber dam and cotton roll isolation techniques during dental treatment in children.
In accordance with PRISMA guidelines, search yielded 1361 articles, with seven RCTs and one non-RCT design meeting the inclusion criteria. Data were extracted on study design, sample size, sealant type, follow-up duration, retention rates, and caries incidence.
The comparison of retention rate between rubber dam and cotton roll at six months difference was non-significant (OR:1.15; p = 0.64) while there was significant difference at 12 month (OR:2.23; p < 0.001). The difference for the marginal integrity was statistically significant at six months (OR:2.00; p = 0.03) while non-significant difference observed (OR:1.74; p = 0.10) at 12 months.
The sealant placed using a rubber dam as an isolation technique showed higher retention than the cotton roll after 12 months. In terms of marginal integrity, the performance of the rubber dam and cotton roll was equivalent at the end of 12 months.
使用棉卷隔离并不总能像使用橡皮障那样提供完全的隔离效果，尤其是在对绝对湿度控制要求严格的操作中。因此，本综述旨在总结和分析以往评估儿童牙科治疗期间使用橡皮障和棉卷隔离技术时窝沟封闭剂的保留率和边缘完整性的研究。
按照PRISMA指南进行检索，共获得1361篇文章，其中7项随机对照试验和1项非随机对照试验设计符合纳入标准。提取了关于研究设计、样本量、封闭剂类型、随访时间、保留率和龋齿发病率的数据。
橡皮障和棉卷在6个月时保留率的比较差异无统计学意义（OR：1.15；p = 0.64），而在12个月时有显著差异（OR：2.23；p < 0.001）。边缘完整性在6个月时差异有统计学意义（OR：2.00；p = 0.03），而在12个月时差异无统计学意义（OR：1.74；p = 0.10）。
使用橡皮障作为隔离技术放置的封闭剂在12个月后显示出比棉卷更高的保留率。在边缘完整性方面，橡皮障和棉卷在12个月末的表现相当。
