概括
低化 (NaOCl) 并没有改善陶支架与质的粘合强度. 该OptiBond S+Orthocem (OS+OC) 协议显示了最低的结合强度,因此不推用于正牙陶支架.
科学领域:
- 牙科材料科学 牙科材料科学
- 矯正牙科 矯正牙科是一種矯正牙科.
- 生物材料工程 生物材料工程
背景情况:
- 在陶正牙支架和牙面膜之间实现持久的纽带对于有效的治疗至关重要.
- 低酸盐 (NaOCl) 有时用于牙科手术,但其对支架粘合效率的影响尚未完全理解.
- 评估不同的结合剂和协议对于优化临床结果至关重要.
研究的目的:
- 为了研究不同化 (NaOCl) 度对质接的陶支架的剪接强度 (SBS) 的影响.
- 在不同的NaOCl度下,比较三种不同的结合系统 (primer + Transbond XT,Optibond S + Transbond XT和Optibond S + Orthocem) 的疗效.
- 用扫描电子显微镜分析面膜的表面形态和粘合界面.
主要方法:
- 九十个牛切口被粘合在陶支架上,使用三种粘合剂系统和三种NaOCl度 (0%,2.5%,5.25%),创建了九个实验组.
- 使用通用测试机器测量了剪接键强度 (SBS).
- 通过扫描电子显微镜 (SEM) 检查了和接口表面形态.
- 统计分析包括克鲁斯卡尔-瓦利斯,恩的测试,以及通用线性模型.
主要成果:
- 在所有结合协议中,不同NaOCl度之间没有发现SBS的显著差异 (p>0.05).
- 在Optibond S+Orthocem (OS+OC) 集团中,债券强度始终是最低的.
- 与5.25%的NaOCl相结合的Optibond S + Transbond XT的结合强度明显高于与2.5%的NaOCl相结合的结合强度 (p<0.05).
- SEM分析表明,在NaOCl应用后,质蚀刻模式发生了变化.
结论:
- 在测试度下预先应用甲酸盐 (NaOCl) 并不能提高陶支架对牙质的粘合强度.
- 由于粘合强度低,不建议使用Optibond S + Orthocem (OS+OC) 粘合协议与固定的陶牙科器件一起使用.
- 临床方案应考虑粘合剂系统的固有特性,而不是NaOCl应用,以获得最佳的陶支架粘合.

Strength and Heat of Hydration
189
The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...

Bonding and Strength of Aggregate
119
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...

Accelerators
63
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.

EDTA: Chemistry and Properties
1.6K
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
2.2K
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...

EDTA: Auxiliary Complexing Reagents
512
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...
