This study aimed to evaluate the influence of silver diamine fluoride (SDF) on the microtensile bond strength (MBS) of glass ionomer cement (GIC) and composite restorations in carious primary dentin and to assess the modes of restoration failure.
Seventy-two carious primary molars were categorized into four groups ( = 18). Samples were treated with 0.9% sodium chloride for 2 months, sectioned at the cementoenamel junction (CEJ), and stored in artificial saliva for 14 days. The SDF-treated groups were exposed to 38% SDF solution, while the control groups underwent restoration without prior SDF application. Specimens were tested for MBS using a universal testing machine, and failure modes were observed under a scanning electron microscope.
The highest MBS was observed in the GIC-SDF group (group II), followed by the composite restoration without SDF (group III), and the lowest in the composite-SDF group (group IV). Adhesive failure predominated in the GIC-SDF group, while the composite-SDF group exhibited mixed failure modes.
The application of SDF did not adversely affect the bond strength of GIC but reduced the bond strength of composite resin. Adhesive failure was more common with GIC-SDF, while mixed failure characterized composite-SDF.

本研究旨在评估氟化亚锡（SDF）对龋损乳牙中玻璃离子水门汀（GIC）和复合树脂修复体微拉伸粘结强度（MBS）的影响，并评估修复体的失败模式。
72颗龋损乳牙被分为四组（每组 = 18）。样本用0.9%氯化钠处理2个月，在牙骨质釉质界（CEJ）处切片，并在人工唾液中储存14天。SDF处理组暴露于38% SDF溶液中，而对照组在未预先应用SDF的情况下进行修复。使用万能试验机测试样本的MBS，并在扫描电子显微镜下观察失败模式。
在GIC-SDF组（第二组）中观察到最高的MBS，其次是未使用SDF的复合树脂修复组（第三组），而复合-SDF组（第四组）中最低。GIC-SDF组中粘结失败占主导，而复合-SDF组表现出混合失败模式。
SDF的应用对GIC的粘结强度没有不利影响，但降低了复合树脂的粘结强度。GIC-SDF中粘结失败更常见，而复合-SDF的特征是混合失败。
