概括

预混合型生物陶水泥 (PPBCs) 的深包装技术与盖技术相比,显示出优越的结合强度和放射性透明度. 单独的PPBC也产生了有利的结果,EDTA预处理对债券强度没有显著影响.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
生物材料科学生物材料科学
牙科材料牙科材料

背景情况:

预混合型生物陶水泥 (PPBC) 越来越多地用于根端填充物.
评估PPBC的不同应用技术对于优化临床结果至关重要.

研究的目的:

为了比较使用PPBC和基于酸盐的密封剂的三种根端填充技术的推出键强度和放射填充.
评估EDTA预处理对这些材料粘合强度的影响.

主要方法:

90个带有人工和侧面通道的根段被分为三个组:单独 (PA),盖盖技术 (LT) 和深包装 (DP).
使用BC-RRM和BC密封剂放置根端填充物,有或没有17%的EDTA预处理.
进行了推出键强度测试和放射性评估.

主要成果:

深包装 (DP) 技术的结合强度明显高于盖子技术 (LT).
在单独的 (PA) 与DP或LT之间没有观察到债券强度的显著差异.
预处理EDTA并没有显著影响推出键的强度.
放射分析显示,PA和DP在主通道中比LT更好地填充,PA在末端优越.

结论:

与盖子技术相比,深包装技术或单独使用PPBC可能为根端填充提供更好的结果.
在PPBC放置之前注入大量密封剂 (盖技术) 可能会损害结合强度和放射性透明度.
在这种情况下,EDTA预处理似乎没有提高PPBC的键强度.

关键词:

Porosity in Cement Paste

Porosity in Cement Paste

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.
The balance of water to cement in the mix is...

Additives and Fillers in Concrete

Additives and Fillers in Concrete

Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.
The...
