概括

银二胺化物 (SDF) 降低了对牙的粘合键强度. 蚀刻和冲洗 (ER) 模式是首选的,用于粘合到经过SDF处理的牙,形成富含和的层.

科学领域:

牙科材料科学牙科材料科学
粘合式牙科粘合式牙科
生物材料是一种生物材料.

背景情况:

银胺化物 (SDF) 用于阻止.
不完全理解SDF对牙粘合剂粘合强度的影响.
调查SDF对牙粘合剂接口的影响对于临床应用至关重要.

研究的目的:

为了评估通用粘合剂对SDF污染的牙的微拉伸键强度 (μTBS).
在SDF应用后,分析粘合剂-牙接口的超形态变化.
为了比较SDF处理牙上的不同粘合剂的自蚀刻 (SE) 和蚀刻和冲洗 (ER) 模式的性能.

主要方法:

96个人的牙被分为声音和SDF污染的牙组.
在污染的牙上涂上SDF,然后冲洗.
在SE或ER模式下使用三个通用粘合剂粘合样本,用树脂复合材料恢复,并测试μTBS.
使用SEM,TEM和STEM与EDX进行了形态分析.

主要成果:

与健康牙相比,受SDF污染的牙显示出明显较低的μTBS.
ER模式通常比SE模式产生更高的μTBS,除了一个例外.
在STEM/EDX分析中,SDF处理的牙中发现了一种独特的含和化物SDF-dentin反应层.

结论:

SDF对通用粘合剂对牙的粘合强度产生负面影响.
建议采用蚀刻冲洗应用模式,将其粘合到被SDF污染的牙上.
观察到的SDF-dentin反应层可能会影响粘合剂粘合.

关键词:

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...
