在酸 (HF) 蚀刻后,短暂的15秒水冲洗有效地清洁了二酸盐表面,与更复杂的方法的结合强度相匹配. 这种简单的技术确保了牙科修复的可比的总结合强度 (TBS).
科学领域:
- 牙科材料科学 牙科材料科学
- 表面处理 表面处理
- 粘合式牙科 粘合式牙科
背景情况:
- 酸 (HF) 蚀刻对于准备脱酸盐表面进行粘合至关重要.
- 有效的蚀刻后清洁对于实现持久的修复至关重要.
- 评估更简单的清洁协议可以优化临床工作流程.
研究的目的:
- 为了比较脱酸盐的总结合强度 (TBS) 在各种蚀刻后清洁方法后.
- 为了确定短时间的水冲洗是否与先进的清洁方案一样有效.
- 评估老化对结合强度和微泄漏的影响.
主要方法:
- 96个脱酸盐标本被 5% HF 蚀刻.
- 评估了六种后蚀刻清洁方法,包括喷水,刷毛和超声波浴.
- 样本被粘合,老化 (3天或150天的热循环),并测试TBS,微泄漏和故障模式.
主要成果:
- 在所有组中,衰老显著减少了TBS.
- 60秒的喷水产生了比酸加超声波清洁更高的TBS.
- 在大多数清洗方法中没有观察到TBS的显著差异,包括15秒的喷水.
结论:
- 在HF蚀刻后15秒喷水是一种简单但有效的清洗方法.
- 这种方法实现了与更复杂的协议相比较的总债券强度.
- 短水冲洗是牙科修复中表面准备的可行选择.

Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:
