概括
玻璃混合水泥 (GH) 与较旧的玻璃离子体水泥 (GIC) 相比,对初级牙的密封性更强. 牙损影响的牙显著增加了微漏,突出了GH对更好的牙修复的物质益处.
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:
- 玻璃离子体水泥 (GIC) 在儿科牙科中广泛使用.
- 评估GIC修复的边际完整性对于长期成功至关重要.
- 受牙影响的牙在实现良好的修复界面方面存在独特的挑战.
研究的目的:
- 为了比较玻璃混合体 (GH),高粘度 (HV) 和树脂修饰 (RM) 玻璃离子体水泥 (GIC) 和声音 (SD) 和受影响的牙 (ACAD) 之间的接口.
- 为了评估材料-牙接口的微泄漏和亲密接触.
- 为了确定GH GIC是否与较旧的GIC代相比提供了更好的密封性.
主要方法:
- 准备了120个主要牙,这些牙在牙中存在密闭腔或牙损伤.
- 用GH (Equia Forte HT-EF),HV-GIC (Equia Fill-E;Ketac Molar-KM) 或RM-GIC (Fuji-II LC-FII;Photac Fill-PF) 修复了空洞. 这两种方法均可进行.
- 使用甲蓝和光学显微镜分析了微漏;通过扫描电子显微镜评估了接口完整性,并使用Python算法量化.
主要成果:
- 在Equia Forte HT (50%),Fuji-II LC (42%) 和Equia Fill (33%) 的声音牙中没有观察到微型泄漏.
- 所有材料在牙损伤受影响的牙中显示出显著更高的微泄漏,而不是健康的牙 (p < 0.05).
- 埃基亚福特HT在健康 (76%) 和牙损伤 (32%) 的亲密接触比例最高,高于其他GIC.
结论:
- 引起的去矿化会对材料-牙接口质量产生负面影响.
- 与之前的HV-GIC和RM-GIC代相比,玻璃混合GIC提供了优越的密封性和亲密接触.
- GH材料代表了一项有前途的进步,可以在一次性牙修复中实现更好的边缘密封.

Hybrid Zones
22.0K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Restorative Care
2.4K
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Characteristics of Life

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

The Looking Glass Self
384
The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical...

Zones of Protection
818
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

Protein-protein Interfaces
14.8K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...
