It has been shown that the use of a sealant offers no advantage with respect to the retentive strength of a composite resin restoration. However, for the improvement of marginal seal and adaptation, the present findings indicate that enamel etching and the application of a sealant, in conjunction with use of a cavity geometry which reduces shrinkage strain, are absolute necessities.
研究表明，就复合树脂修复体的固位强度而言，使用封闭剂并无优势。然而，为了改善边缘封闭和贴合性，目前的研究结果表明，酸蚀釉质并应用封闭剂，结合使用能降低收缩应变的洞形，是绝对必要的。
