概括

与酸水泥 (CSM) 相比,现代基于树脂的生物活性材料对牙的重矿化能力有限. CSM有效地促进了在牙-物质接口的矿物沉积,这表明它具有更高的修复潜力.

科学领域:

生物材料科学生物材料科学
牙科材料牙科材料
矿化研究矿化研究

背景情况:

基于树脂的材料 (RBM) 越来越多地被销售为"生物活性",具有牙重矿化潜力.
酸水泥 (CSM) 以其诱导矿物沉积和促进愈合的能力而闻名.

研究的目的:

评估和比较现代RBM与CSM的牙重矿化能力.
通过使用先进的分析技术,评估材料-牙接口的矿物沉积.

主要方法:

经过测试的CSM (ProRoot MTA,MTA Angelus,Biodentine,TheraCal LC) 和RBM (ACTIVA Bioactive,ACTIVA Presto,Predicta Bioactive Bulk) 已经通过了测试,这些产品中使用的产品包括:
通过扫描电子显微镜 (SEM) 和能量分散式X射线光谱 (EDX) 评估矿物沉量.
在基线和浸入模拟体液28天后分析的标本,计算Ca/P比率.

主要成果:

CSM显示了显著的表面降水,有效地填补了材料和牙之间的差距.
环形机械表现出最小的矿物沉,并且没有重新矿化牙-材料接口.
与RBM相比,CSM在诱导矿物沉积方面表现出更好的能力.

结论:

现代"生物活性"的RBM在诱导牙重矿化方面不如CSM有效.
CSM更适合在牙-材料界面促进修复过程.
这项研究强调了CSM的优越矿化能力,而不是当前的RBM.

关键词:

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Essential Minerals for Bone Health

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Osteoclasts in Bone Remodeling

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...
