本研究的目的是评估在乳牙中使用不同粘合系统放置的复合修复体的临床性能。在 32 名患者中，使用分口设计放置了 128 个复合修复体，如下（4 组/患者）：三步蚀刻和冲洗（第 1 组）、两步蚀刻和冲洗（第 2 组）、两步自蚀刻（第 3 组）和一步自蚀刻（第 4 组）。根据 FDI 标准，在基线以及 6、18 和 36 个月时对修复体进行临床评估。粘合系统之间的修复体固位没有显着差异 (p > 0.05)。随着时间的推移，所有组的边缘适应均出现统计显着下降，而第 3 组和第 4 组的表面和边缘染色显着增加 (p < 0.05)。蚀刻和冲洗粘合剂系统比自蚀刻粘合剂系统具有更好的边缘适应性（p < 0.05）。结论是，对乳牙釉质进行预蚀刻可能有助于改善乳牙自酸蚀粘合系统的临床性能。
The purpose of this study was to assess the clinical performance of composite restorations placed with different adhesive systems in primary teeth. In 32 patients, 128 composite restorations were placed using a split-mouth design as follows (4 groups/patient): three-step etch-and-rinse (Group 1), two-step etch-and-rinse (Group 2), two-step self-etch (Group 3), and one-step self-etch (Group 4). The restorations were clinically evaluated at baseline and at 6, 18, and 36 months according to the FDI criteria. There was no significant difference between the adhesive systems in retention of the restorations (p > 0.05). Over time, there was a statistically significant decrease in marginal adaptation in all groups, whereas surface and marginal staining significantly increased in Groups 3 and 4 (p < 0.05). The etch-and-rinse adhesive systems resulted in better marginal adaptation than the self-etch adhesive systems (p < 0.05). It was concluded that preetching of the primary enamel might help improve the clinical performance of the self-etch adhesive systems in primary teeth.
