概括

帕帕因脱蛋白化显著增强了Transbond XT.的正义牙科支架键强度. 这种处理还提高了树脂修饰玻璃离子体水泥和Biofix的结合强度,达到可比水平.

科学领域:

矯正牙科矯正牙科是一種矯正牙科.
牙科材料科学牙科材料科学
生物材料是一种生物材料.

背景情况:

乳脱蛋白化对于最佳的正统牙科支架粘附至关重要.
作为一种新的脱蛋白剂,正在探索一种蛋白质分解酶 - - 帕帕因.
评估 papain 对各种正牙粘合剂的剪接键强度 (SBS) 的影响是必不可少的.

研究的目的:

为了评估10%的帕帕因作为质脱蛋白剂的有效性.
为了比较Transbond XT,树脂修饰玻璃离子体水泥 (RMGIC) 和Biofix在帕帕因处理后的剪接强度 (SBS).
为了确定帕帕因脱蛋白化是否提高了这些粘合剂的粘合强度.

主要方法:

进行了一项单中心,双盲,分口随机对照试验.
来自20名参与者的80个前被分为四组:Transbond XT (papain/没有papain),Biofix (papain) 和RMGIC (papain).
切割键强度 (SBS) 在28天后使用通用测试机测量,然后进行统计分析 (ANOVA,Tukey的后期测试).

主要成果:

在所有组中观察到SBS的统计学上显著差异 (P = 0.002).
与未经治疗的对照组相比,Papain脱蛋白化显著增加了Transbond XT的SBS (P = 0.03).
在未经治疗的Transbond XT和接受了papain治疗的RMGIC或Biofix之间没有发现SBS的显著差异.

结论:

10%的帕帕因有效地降低了牙面膜的蛋白质,增强了正粘合剂的SBS.
帕帕因治疗将RMGIC和Biofix的结合强度提高到与未经处理的Transbond XT.相比的水平.
帕帕因代表了一种改善正统牙结合程序的有前途的药物.

Bonding and Strength of Aggregate

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...
