内牙灌溶液的选择显著影响牙结合强度. 将甲-EDTA-甲灌与自蚀粘合剂相结合,可以获得最高的微拉伸键强度.
科学领域:
- 牙科材料科学 牙科材料科学
- 牙周内科医院 牙周内科医院 牙周内科医院
- 粘合式牙科 粘合式牙科
背景情况:
- 牙结合强度对于牙修复的长寿至关重要.
- 内牙灌协议可以影响牙-牙接口的完整性.
- 了解灌溶液和粘合剂系统之间的相互作用是必不可少的.
研究的目的:
- 为了评估不同的内灌协议如何影响微拉伸键强度 (μTBS) 到牙.
- 为了比较蚀刻和冲洗 (ER) 与各种灌策略的自蚀刻 (SE) 粘合系统的性能.
- 为了确定最佳的灌和粘合剂组合,以提高粘合强度.
主要方法:
- 准备了80个人的牙,并接受了五个不同的27分钟内灌方案.
- 在灌后,应用了蚀刻和冲洗 (Optibond FL) 或自蚀刻 (Clearfil SE Bond) 粘合剂.
- 丹丁复合棒是用来测试微拉伸键强度 (μTBS) 和故障模式分析的.
主要成果:
- 在大多数灌协议中,蚀刻和冲洗粘合剂通常比自蚀刻粘合剂产生更高的μTBS.
- NaOCl-EDTA-NaOCl灌协议导致了最高的μTBS,特别是在自蚀刻粘合剂组内.
- 在使用蚀刻和冲洗粘合剂时,灌协议的有效性降低了,除了特定的序列.
结论:
- 选择内牙灌方案应仔细与所选择的粘合剂系统相匹配,特别是自蚀刻粘合剂.
- 与Clearfil SE Bond相结合的NaOCl-EDTA-NaOCl灌序列显示出优越的微拉伸键强度.
- 粘合系统的选择显著调节了内牙灌对牙结合强度的影响.

Effects of EDTA on End-Point Detection Methods
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...
