概括
该研究发现,无论是粘合剂蚀刻模式还是凝固时间都没有显著影响到用酸基密封剂填充的根通道中的纤维后结合强度. 这些发现表明,纤维后安置的临床程序具有灵活性.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科材料科学 牙科材料科学
- 粘合式牙科 粘合式牙科
背景情况:
- 基于酸的密封剂提供了诸如氧酸盐形成之类的好处,但可能会使空间后准备复杂化.
- 套装密封剂可能会损害纤维柱和根牙之间的结合强度.
- 粘合策略和凝固时间是影响纤维后结合强度的潜在因素.
研究的目的:
- 为了评估一个粘合剂系统的不同蚀刻模式 (自蚀刻与蚀刻和冲洗) 的影响.
- 评估凝固后时间 (即时与延迟) 对推出键强度的影响.
- 为了确定纤维柱的这些影响,这些纤维柱在根通道中结,用酸基密封剂堵塞.
主要方法:
- 根据蚀刻方式和凝固时间 (即时或延迟7天) 将54颗牙分为6组.
- 用基于酸盐的密封剂堵塞了根管道,并准备了后位空间.
- 纤维柱子使用通用树脂水泥进行了水泥化,随后在不同根部区域的1毫米切片上进行了推出键强度测试.
主要成果:
- 关于蚀刻模式 (自蚀刻或蚀刻和冲洗) 的推出键强度没有发现统计学上显著的差异.
- 空间后的准备和凝固时间 (即时或延迟) 并没有显著影响结合强度.
- 根通道区域 (冠状,中部,顶部) 也没有显著影响债券强度.
结论:
- 粘合剂系统的蚀刻模式不会影响以酸为基础的材料密封的根通道中的纤维后结合强度.
- 固化后的时间,无论是立即的还是延迟的,都不会显著改变纤维柱的结合强度.
- 在这种情况下,关于粘合剂的应用和凝固时间的临床选择似乎对纤维柱的粘合强度的影响最小.

Hydration of Cement
201
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...

Porosity in Cement Paste
117
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
