酸酸盐水泥酸水泥

背景情况:

生物牙是一种基于酸的材料,以其生物活性而闻名.
压缩强度和离子释放对于Biodentine的临床性能至关重要.
研究常见的内牙灌剂对生物牙特性的影响是必不可少的.

研究的目的:

为了评估双冲洗HEDP (DR HEDP),乙烯基二胺三酸 (EDTA) 和二酸盐 (NaOCl) 对Biodentine离子释放的影响.
评估这些灌剂对Biodentine压力强度的影响.
为了比较不同灌剂对Biodentine属性的有害影响.

主要方法:

准备了80个Biodentine标本,并分为四组.
群体接受了17%的EDTA,DR HEDP,2.5%的NaOCl或1分钟的蒸水治疗.
使用原子吸收光谱测量测量离子释放,并测试压力强度.

主要成果:

二 (NaOCl) 导致离子释放率最低,而17%的EDTA显示最高.
蒸水的压力强度最高,而2.5%NaOCl的压力强度最低.
与DR HEDP相比,EDTA显著降低了压力强度,其有害影响最小.

Strength of Cement

Strength of Cement

Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...
