概括
全面粘合剂显著提高了玻璃离子体对母牙的粘合强度,改善了儿科牙科的临床成功. 这一发现为一个常见的牙科挑战提供了有希望的解决方案.
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
背景情况:
- 玻璃离子体对于恢复母牙至关重要.
- 将玻璃离子体粘合到初级牙上,在儿科牙科中是一个重大挑战.
研究的目的:
- 为了评估树脂改性玻璃离子体 (RMGI) 和高粘度玻璃离子体水泥 (Hv-GIC) 对初级牙的微剪切键强度 (μSBS).
- 评估一种通用粘合剂在提高这种粘合强度方面的有效性.
主要方法:
- 从人类初级犬的60个标本被分为六组,测试两种类型的玻璃离子体 (RMGI和HV-GIC) 有和没有通用粘合剂 (即时或延迟固化).
- 测量了微剪断键强度 (μSBS),并使用立体显微镜和SEM分析了故障模式.
- 数据使用双向ANOVA和Tukey的后期测试进行了统计分析.
主要成果:
- 通用粘合剂的应用显著增加了两种玻璃离子体类型的μSBS (p < 0.0001).
- 在通用粘合剂的立即和延迟固化之间没有观察到粘合强度的显著差异 (p = 0.157).
- 玻璃离子体的类型没有显著影响结合强度 (p = 0.305),混合失效占主导地位.

01:12Bonding and Strength of Aggregate
153
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...

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
