(1) Background: Alkasite is a novel restorative material that has attracted interest in recent years because of its distinctive characteristics, including its high translucency and excellent biocompatibility. It is comparable to glass ionomer cement (GIC) and resin-modified glass ionomer cement (RMGIC) due to its fluoride-release ability and usage in esthetically concerned areas. This study aimed to assess the shear bond strength (SBS) of Alkasite restorative material in comparison with GIC and RMGIC (2) Methods: The study sample included 120 extracted sound primary molars and was randomly split into three groups, including group 1: RMGIC; group 2: Alkasite; and group 3: GIC. Each group was then sub-grouped into immediate and delayed loading. SBS was measured for each group using a universal testing machine. One-way analysis of variance with Tukey's post hoc test and an independent t-test were used for statistical analyses (3) Results: The immediate SBS was higher in Alkasite, followed by RMGIC and GIC, with means of 10.84 ± 1.96, 10.64 ± 1.74, and 6.09 ± 1.75, respectively. However, there was no significant difference between Alkasite and RMGIC ( = 0.94), whereas RMGIC and Alkasite showed significantly higher values than GIC, with < 0.0001. Regarding delayed SBS, no significant difference was noted between Alkasite and RMGIC ( = 0.14), whereas both showed significantly higher values than GIC, with mean values of 6.30 ± 1.44, 5.556 ± 1.38, and 3.29 ± 0.61, respectively ( < 0.0001). (4) Conclusions: Our findings show that RMGIC and Alkasite have comparable outcomes to each other and better outcomes when compared with conventional GIC.
（1）背景：碱式铝硅玻璃是一种新型修复材料，近年来因其独特的特性，包括高透明度和优异的生物相容性而备受关注。由于其氟释放能力以及在美学相关领域的应用，它可与玻璃离子水门汀（GIC）和树脂改性玻璃离子水门汀（RMGIC）相媲美。本研究旨在评估碱式铝硅玻璃修复材料与GIC和RMGIC相比的剪切粘结强度（SBS）。（2）方法：研究样本包括120颗拔除的健康乳牙，并随机分为三组，包括第1组：RMGIC；第2组：碱式铝硅玻璃；第3组：GIC。然后每组再分为即刻加载和延迟加载亚组。使用万能试验机测量每组的SBS。采用单因素方差分析和Tukey事后检验以及独立t检验进行统计分析。（3）结果：碱式铝硅玻璃的即刻SBS较高，其次是RMGIC和GIC，平均值分别为10.84±1.96、10.64±1.74和6.09±1.75。然而，碱式铝硅玻璃和RMGIC之间无显著差异（P = 0.94），而RMGIC和碱式铝硅玻璃的值均显著高于GIC，P < 0.0001。关于延迟SBS，碱式铝硅玻璃和RMGIC之间无显著差异（P = 0.14），而两者的值均显著高于GIC，平均值分别为6.30±1.44、5.556±1.38和3.29±0.61（P < 0.0001）。（4）结论：我们的研究结果表明，RMGIC和碱式铝硅玻璃彼此的结果相当，且与传统GIC相比结果更好。
