概括

像CPP-ACP,P11-4和白银胺化物 (SDF) 这样的重矿化疗法显著改善了牙粘合强度对牙损伤受影响的牙. CPP-ACP证明了最实质性的债券强度增强,为恢复性牙科提供了有价值的策略.

科学领域:

牙科材料科学牙科材料科学
皮肤病学皮肤病学皮肤病学
粘合式牙科粘合式牙科

背景情况:

由于基质结构和组成的改变,牙受病影响的粘附性受到损害.
再矿化剂正在探索加强牙和增强粘合性粘合.
普遍的粘合剂系统被广泛使用,但它们对牙损伤的有效性需要评估.

研究的目的:

评估三种重矿化剂CPP-ACP,P11-4和SDF对通用粘合剂微拉伸键强度 (μTBS) 的影响.
为了比较蚀刻和冲洗与自蚀刻策略的有效性,当应用于受脏影响的复矿化牙时.
确定最佳的再生矿物化方案,以改善对牙基板的粘附性.

主要方法:

70个人的牙被人为地去矿化,以模拟牙损伤的牙.
样品被CPP-ACP,P11-4或SDF处理,或没有处理.
使用蚀刻和冲洗和自蚀刻模式应用了通用粘合剂,随后进行了复合材料恢复和μTBS测试.

主要成果:

与健康牙 (41.3 MPa) 相比,未经处理的牙表现出明显较低的μTBS (18.3 MPa).
所有重矿化剂都改善了μTBS; CPP-ACP产生了最高的键强度 (约. 30MPa),其次是P11-4和SDF (大约为30MPa),其次是P11-4和SDF (大约为30MPa),其次是P11-4和SDF (大约为30MPa). 22-24 MPa) 的情况.
蚀刻和冲洗通常显示出比自蚀刻更高的μTBS,尽管在统计学上并不显著.

结论:

用CPP-ACP,P11-4或SDF进行预处理,可显著提高通用粘合剂对牙损伤受损的粘合强度.
在债券强度方面,CPP-ACP提供了最显著的改善,接近了健康牙所见的水平.
重矿化方案是改善损坏牙的修复结果的有希望的补充.

关键词:

在CPP-ACP中使用.这是一种P11-4.牙受病影响的牙.微拉力键的强度是微拉力键的强度.重矿化是指重矿化的过程.银胺化物银胺化物全面的粘合剂普遍的粘合剂

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...

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...

EDTA: Chemistry and Properties

EDTA: Chemistry and Properties

Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or bidentate ligands due to the chelate effect. Examples of polydentate ligands are ethylenediaminetetraacetic acid (EDTA), crown ethers, and cryptands. The most important feature of optimal polydentate ligands is the ability to form 1:1 complexes in a single-step process. Amino carboxylic acid derivatives are frequently used as complexing agents. EDTA is...
