概括
牙粘合剂可以在再生性内牙科手术后部分防止牙变色,特别是在使用三重抗生素糊时. 然而,在这项研究中,无法完全预防颜色变化.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科材料科学 牙科材料科学
背景情况:
- 再生性内牙术程序 (REP) 的目的是恢复肉皮活力和牙结构.
- 牙变色是REP后的潜在并发症,影响美学.
- 登丁粘合剂用于密封纸,但它们在防止REP引起的变色方面的有效性尚不清楚.
研究的目的:
- 评估牙粘合剂在防止REP后牙变色方面的有效性.
- 为了比较用不同内药物和牙结合剂治疗的牛切口的色彩稳定性.
主要方法:
- 在体外研究使用120个牛切口.
- 两个因素:牙结合剂的应用 (是/不是) 和五种内通道药物类型 (三重抗生素糊 [TAP],双抗生素糊 [DAB],氧化 [CH],修改的TAP [TAPM],控制 [CTL]).
- 颜色变化 (ΔE00) 用CIEDE2000公式在28天内测量.
主要成果:
- 三重抗生素糊 (TAP) 组显示出最显著的颜色变化,无论使用粘合剂.
- 纸腔中的牙粘合剂提供了与无密封相比,防止变色的保护作用.
- 所有测试组都表现出超过临床可接受值的颜色变化,主要是由于亮度减少和向绿色转移.
结论:
- 用牙粘合剂密封纤维室可以减轻,但不能消除REP中TAP引起的变色.
- 需要进行进一步的研究,以制定在REP中完全预防牙变色的策略.

01:18Effects of EDTA on End-Point Detection Methods
272
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...

2.4K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...
