This study compared the clinical performance of the ultraviolet light-initiated fissure sealant and composite system (Nuva-Seal/Nuva-Fil) with a chemically activated system (Adaptic Bonding Agent/Adaptic). A total of 63 fractured permanent anterior teeth involving only enamel and dentin were restored. All teeth were isolated with rubber dams, and the acid etch technique was used. The degree of success was determined from an assessment of retention, marginal integrity, marginal staining, and color change. The restorations were evaluated at 3, 6, 12, 18, and 24 months postoperatively. Of the restorations, 93% were retained in both groups of patients after two years. Varying degrees of marginal problems (lack of marginal integrity or marginal staining) were directly attributable to the extension of the bonding medium and the composite in relation to the conditioned enamel and to each other. Repolishing of the margins should be considered at the time of the recall appointments to improve the quality of restoration.
本研究比较了紫外线引发的窝沟封闭剂与复合树脂系统（Nuva-Seal/Nuva-Fil）和化学活化系统（Adaptic粘结剂/Adaptic）的临床性能。共修复了63颗仅涉及釉质和牙本质的恒牙折断病例。所有牙齿均用橡皮障隔离，并采用酸蚀技术。通过对固位、边缘完整性、边缘染色和颜色变化的评估来确定成功程度。术后3、6、12、18和24个月对修复体进行评估。两年后，两组患者中93%的修复体得以保留。不同程度的边缘问题（边缘完整性欠佳或边缘染色）直接归因于粘结剂和复合树脂相对于酸蚀处理后的釉质以及彼此之间的延伸情况。复诊时应考虑对边缘进行再抛光，以提高修复质量。
