概括
乙醇预处理增强了对牙的通用粘合剂的粘合强度,而蚀刻时间和乙醇都会影响金属蛋白酶 (MMP) 活性. 这项研究调查了改善牙科修复的这些因素.
科学领域:
- 牙科材料科学 牙科材料科学
- 粘合式牙科 粘合式牙科
- 生物材料是一种生物材料.
背景情况:
- 根性牙结合强度对于内牙治疗牙中纤维后保留至关重要.
- 金属蛋白酶 (MMPs) 可以降解混合层,损害长期键的耐用性.
- 水友多模式通用粘合剂提供了多功能性,但需要优化应用协议.
研究的目的:
- 评估不同酸蚀刻时间和乙醇预处理对通用粘合剂即时粘合强度的影响.
- 评估这些协议对MMPs在根性牙中的凝溶解活性的影响.
主要方法:
- 一项实验室研究使用60根单根牙进行了四次粘合方案,涉及不同的蚀刻时间 (15s vs 30s) 和乙醇预处理.
- 纤维柱子使用双固化树脂水泥进行了水泥化,随后进行了推出键强度和纳米泄漏测试.
- 在现场抽图被用于量化固有的MMP在粘合剂-牙接口上的凝活性.
主要成果:
- 乙醇预处理显著增加了即时推出键强度 (p < 0.01),不管蚀刻的持续时间.
- 所有组都表现出MMP的凝溶解活性;30秒的蚀刻时间显示了活性显著增加.
- 乙醇预处理显著降低了粘合剂接口内的MMP活性 (p < 0.01).
结论:
- 仅仅是蚀刻时间并没有显著影响通用粘合剂的性能.
- 乙醇预处理有利于即时的键强度,并降低MMP活性,可能改善混合层的稳定性.
- 需要进一步的体内研究来确认这些发现的长期临床影响.

EDTA: Chemistry and Properties
1.9K
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...

Masking and Demasking Agents
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...
