- 通过使用不同的最终灌协议来评估Ca (OH) 2去除后的粘合剂接口质量.
主要方法:
- 根管道被仪器化并用Ca () 2填充.
- 标本通过四种灌方案进行了Ca(OH) 2去除:蒸水,1%NaOCl,17%EDTA或17%EDTA+1%NaOCl.
- 根被填充AH Plus密封剂和gutta-percha,然后切割用于POBS测试和SEM分析.
主要成果:
- 与对照组 (蒸水) 相比,EDTA组对POBS产生了负面影响.
- EDTA + NaOCl 组表现出与对照组和 NaOCl 组相似的 POBS.
- 在蒸水,NaOCl和EDTA + NaOCl组中观察到一个均的,无间隙的粘合接口.
- 在蒸水和EDTA + NaOCl组中观察到更高的密封标签形成.
结论:
- 用EDTA单独进行最终灌会对AH Plus密封剂与根牙的结合强度产生负面影响.
- 使用EDTA,然后使用NaOCl进行最终灌,可以获得统一的,无间隙的粘合界面和增强的密封标签形成,类似于蒸水.
- 选择最终灌方案对于优化根管治疗中的键强度和界面完整性至关重要.

Factors Affecting Solubility
33.4K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Bonding and Strength of Aggregate
153
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...

Testing Water Quality
110
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
