概括

这项研究比较了玻璃离子体水泥,发现Riva光疗SDI具有优越的压力强度. 制造商的成分对GC产品的强度的影响比聚合方法更大.

科学领域:

牙科材料科学牙科材料科学
生物材料工程生物材料工程

背景情况:

玻璃离子体水泥 (GIC) 在修复性牙科中被广泛使用.
它们的机械性能,特别是压力强度,对于临床寿命至关重要.
不同的聚合机制 (自固化与光固化) 可能会影响GIC性能.

研究的目的:

评估和比较GICs与不同聚合机制的压力强度.
建立基于机械性能的GIC的性能类别.

主要方法:

四种GIC材料进行了测试:两种自我固化 (GC Fuji IX GP Fast,Maxxion R FGM) 和两种光固化 (GC Fuji II LC,Riva Light Cure SDI) 的材料.
根据ISO 9917-1:2007标准准备了圆柱形样本.
在进行压缩测试之前,样本在37°C的人工唾液中储存了15天.

主要成果:

在GIC之间观察到压力强度的显著差异 (p < 0.001).
瑞瓦光疗SDI证明了最高的压力强度 (1,603.7 kN).
富士九号GP Fast和富士二号LC的压力强度在统计上相似 (p=0.911),这表明制造商的成分是关键因素.

结论:

GICs可以分为高 (Riva Light Cure SDI),中等 (GC产品) 和基本 (Maxxion R FGM) 的性能组.
这些发现提供了基于特定材料要求的临床选择框架.
具有不同聚合机制的GC产品的等价性为临床应用提供了灵活性,特别是在儿科牙科中.

Strength of Cement

Strength of Cement

Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

Mortar Properties

Mortar Properties

Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...
