概括
酸 (CPP-ACP) 显著增强了在正牙治疗期间的质再矿化. 与金属支架相比,使用CPP-ACP的陶支架在预防白斑病变方面表现出更好的结果.
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
- ортодонтика研究 ортодонтика研究
背景情况:
- 使用固定金属或陶支架的正牙治疗增加了白斑病变 (WSL) 的风险,原因是斑块积累和酸暴露.
- 早期的WSL代表了牙面膜的去矿化,这是牙损伤的前体.
- 制定预防策略至关重要,以减轻在正牙治疗期间的牙损伤.
研究的目的:
- 为了评估甲上素化-无形酸盐 (CPP-ACP) 的重矿化潜力.
- 评估CPP-ACP对最小化在正义牙科支架粘接过程中质损失的影响.
- 为了比较CPP-ACP与金属与陶支架在预防WSL方面的有效性.
主要方法:
- 一项体外研究使用了44个提取的前,经过了去矿化循环.
- 牙是用金属或陶支架粘合在一起的,有或没有CPP-ACP处理.
- 扫描电子显微镜 (SEM) 分析了剥离后的质表面变化.
主要成果:
- 在两组之间观察到质表面完整性的统计学上显著差异 (p < 0.0001).
- 与CPP-ACP相结合的陶支架显示出完全表面再矿化率最高 (90.9%).
- 使用CPP-ACP的金属支架显示出大量的重矿化 (72.72%),而对照组显示出严重的质损伤.
结论:
- CPP-ACP显著促进了质的重矿化,并最大限度地减少了在正牙治疗期间的去矿化.
- 陶支架和CPP-ACP的组合提供了对白斑病变形成的优越保护.
- CPP-ACP是一种有前途的药物,可以在接受固定牙科治疗的患者中预防牙质去矿化.

01:18Effects of EDTA on End-Point Detection Methods
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...

01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
