1957年Fukada和Yasuda报告了关于“骨的压电效应”。这项研究表明当骨结构有机械变形出现时,在骨的另一面即产生电荷。这种效应是由于沿着分子平面和围绕着骨单位结构内的中心点的正负电荷不对称的分布所引起的。在这项研究以后,另一些作者也指出骨有压电特性。体外的研究表明500克的力量能引起0.5mm 的变形,产生大约2 mV 的电压;关于这些电荷的来源还不清楚。不论干的还是湿的胶原都有压电效应。口腔结构的研究表明釉质没有压电效应,牙本质有压电效应。有些理论认为作用在组织上引起电
In 1957 Fukada and Yasuda reported on “Bone Piezoelectric Effect.” This study shows that when mechanical deformation of the bone structure occurs, the other side of the bone that is charged. This effect is due to the asymmetric distribution of positive and negative charges along the molecular plane and around the center within the bone unit structure. After this study, other authors also pointed out that the bone has piezoelectric properties. In vitro studies have shown that 500 grams of force can cause 0.5 mm of deformation, resulting in about 2 mV voltage; the source of these charges is unclear. Both dry and wet collagen has a piezoelectric effect. Oral structure studies have shown that enamel has no piezoelectric effect and that dentin has a piezoelectric effect. Some theories suggest that the action causes electricity in the organization
