The material structure and chemical elemental composition of a new self-adhesive composite hybrid were investigated. The bonding performance when applied on flat (FLAT) vs high C-factor class-I cavity-bottom (CAVITY) dentin and in light-cure (LC) vs self-cure (SC) mode was determined.
The self-adhesive bulk-fill composite Surefil One (Su-O; Dentsply Sirona) was compared with the resin-modified glass-ionomer Fuji II LC Improved (Fuji2LC; GC) and the ion-releasing alkasite material Cention N (CentionN; Ivoclar Vivadent). The material structure was examined with SEM and TEM, while the chemical elemental composition was analyzed using EDS. The immediate and aged microtensile bond strength (μTBS) of Su-O_LC/SC was compared to that of Fuji2LC applied without any pre-treatment, and to that of CentionN applied following bonding with Adhese Universal (AU) (Ivoclar Vivadent) in self-etch mode (AU/CentionN). All restorative materials were bonded onto FLAT and CAVITY dentin. Statistical analysis was performed with the Kruskal-Wallis nonparametric test.
EDS analysis revealed that Su-O was richer in C and P than the reference restorative materials. Applied to FLAT dentin, the significantly highest immediate and aged μTBS were recorded for AU/CentionN, which were not significantly different only from Su-O_LC. Applied to CAVITY dentin, the significantly highest immediate μTBS was recorded for AU/CentionN, which did not differ significantly only from Su-O_SC. Su-O_LC bonded to CAVITY dentin suffered from a high incidence of pre-test failures.
While Su-O_LC bonded effectively and durably to FLAT dentin, Su-O_SC bonded more favorably than Su-O_LC in class-I cavities, which was probably related to shrinkage stress variously challenging the respective bond.
研究了一种新型自粘接复合混合材料的物质结构和化学元素组成。测定了在平面（FLAT）与高 C 因素 I 类腔底（CAVITY）牙本质以及在光固化（LC）与自固化（SC）模式下应用时的粘结性能。
将自粘接块状填充复合材料 Surefil One（Su-O；登士柏西诺德）与树脂改性玻璃离子体 Fuji II LC Improved（Fuji2LC；GC）和离子释放 alkasite 材料 Cention N（CentionN；义获嘉伟瓦登特）进行比较。使用 SEM 和 TEM 检查材料结构，并用 EDS 分析化学元素组成。比较 Su-O_LC/SC 的即时和老化微拉伸粘结强度（μTBS）与未进行任何预处理的 Fuji2LC 以及在自酸蚀模式下用 Adhese Universal（AU）（义获嘉伟瓦登特）粘结后的 CentionN（AU/CentionN）的粘结强度。所有修复材料均粘结在 FLAT 和 CAVITY 牙本质上。采用 Kruskal-Wallis 非参数检验进行统计学分析。
EDS 分析表明，Su-O 比参考修复材料富含 C 和 P。应用于 FLAT 牙本质，AU/CentionN 记录到的即时和老化 μTBS 显著最高，仅与 Su-O_LC 无显著差异。应用于 CAVITY 牙本质，AU/CentionN 记录到的即时 μTBS 显著最高，仅与 Su-O_SC 无显著差异。Su-O_LC 粘结到 CAVITY 牙本质时，预测试失败的发生率较高。
虽然 Su-O_LC 有效且持久地粘结到 FLAT 牙本质，但 Su-O_SC 在 I 类窝洞中比 Su-O_LC 更有利地粘结，这可能与收缩应力对各自粘结的不同挑战有关。
