概括

过期的牙粘合剂在过期两年后仍然可以有效地粘合到牙上. 然而,与牙的结合强度明显受到损害,这表明这种基质的疗效降低了.

科学领域:

牙科牙科是指牙科的专业.
生物材料科学生物材料科学
粘合式牙科粘合式牙科

背景情况:

牙粘合剂对于修复至关重要.
了解到期日对粘合剂性能的影响对于临床实践至关重要.
OptiBond FL是一种广泛使用的蚀刻和冲洗粘合剂.

研究的目的:

为了评估过期的蚀刻和冲洗牙粘合剂的粘合强度.
为了比较OptiBond FL在过期两年后的表现,与其在日期控制相比.

主要方法:

微拉伸键强度测试是在人类牙和牙样本上进行的.
该研究使用了一种蚀刻和冲洗粘合剂 (OptiBond FL),在过期两年后进行了测试.
统计分析包括独立的t测试和曼-惠特尼U测试.

主要成果:

在日期和过期的粘合剂之间,没有观察到质粘合剂的粘合强度有显著差异 (p = 0.77).
过期的粘合剂对牙的结合强度显著降低 (p < 0.001).
已过期组中的20个牙样本在预测中失败,表明完全的结合失败.

结论:

过期的蚀刻和冲洗粘合剂可能会保持对质粘合的有效性.
当使用过期的蚀刻和冲洗粘合剂时,与牙的结合会显著减弱.
过期粘合剂的临床使用需要仔细考虑,特别是牙粘合剂.

Bonding and Strength of Aggregate

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...
