概括

与矿物三氧化聚合物 (MTA) 相比,当与各种牙科修复材料结合时,Theracal PT在实验室中表现出优异的剪切结合强度 (SBS). 这表明Theracal PT可能会提供更持久的牙科修复.

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
恢复性牙科恢复性牙科

背景情况:

评估牙封闭材料的粘合强度对于恢复寿命至关重要.
矿物三氧化物聚合物 (MTA) 和双固化,树脂修饰的酸盐材料,如Theracal PT,被用作直接的纸封装剂.
了解它们与常见的修复材料的相互作用,对于临床成功至关重要.

研究的目的:

为了将MTA和Theracal PT的体外剪接强度 (SBS) 与复合树脂,复合物和散装复合物进行比较.
在立体显微镜检查下评估这些材料组合的结合失效模式.

主要方法:

准备了90个带有中孔的烯酸标本,并将其分为MTA和Theracal PT组.
每组根据修复材料分为三个子组:复合树脂,复合物和散装复合物 (n=15).
切割键强度测试使用通用测试机进行,然后对故障模式进行立体显微镜分析. 数据使用双向ANOVA和Tukey测试进行了分析.

主要成果:

甲状腺PT表现出明显高于MTA的SBS值 (p < 0.001).
在与MTA一起使用的修复材料中,没有发现SBS的显著差异.
在Theracal PT +复合树脂和Theracal PT +复合物组之间观察到SBS的显著差异 (p < 0.001).

结论:

与MTA相比,theracal PT在体外显示出优越的结合强度.
甲状腺PT显示出创造持久牙修复的潜力,因为它可靠地与各种修复材料结合.
需要进一步的临床研究来证实Theracal PT.的长期性能.

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...

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...
