概括
用MEP和HF等陶修复原料/蚀刻剂污染牙,显著降低了自我蚀刻 (SE) 粘合效率. 然而,蚀刻和冲洗 (E&R) 粘合物仍然不受这种污染的影响,即使经过6个月的老化.
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:
- 陶修复通常需要相邻的维修.
- 在修复过程中牙被原料/蚀刻剂污染可能会影响粘合.
- 了解这种污染对不同粘合剂系统的影响对于临床成功至关重要.
研究的目的:
- 评估牙污染与陶修复原料/蚀刻剂对使用通用粘合剂 (UA) 在蚀刻和冲洗 (E&R) 和自蚀刻 (SE) 模式中的粘合的影响.
- 在类似的污染条件下,将粘合性能与黄金标准的SE粘合剂进行比较.
主要方法:
- 人类牙被使用,牙被污染了Monobond Etch & Prime (MEP) 或IPS陶蚀刻凝 (HF).
- 在E&R和SE模式中使用单一债券通用 (SBU),在SE模式中使用Clearfil SE债券 (CSE) 进行了结合.
- 在人工唾液中经过1周和6个月的老化后,测试了微拉力键强度.
主要成果:
- 与未被污染的对照组相比,蚀和冲洗 (E&R) 对污染的牙的粘合没有显著差异.
- 与受MEP和HF污染的牙相结合的自我蚀刻 (SE) 效果明显低于对照的效果.
- 6个月的老化并没有对E&R债券产生负面影响,但进一步降低了SE债券的有效性.
结论:
- 牙污染MEP和HF显著损害了自蚀刻 (SE) 粘合剂的粘合.
- 蚀刻和冲洗 (E&R) 粘合协议更适应陶修复剂的污染.
- 临床方案应考虑污染对SE结合系统的潜在影响.

Bonding and Strength of Aggregate
429
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...

Masking and Demasking Agents
3.4K
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...

EDTA: Auxiliary Complexing Reagents
1.2K
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...

EDTA: Chemistry and Properties
3.2K
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...
