美国的牙科学家认为,以传统的方法(如用银合金、硅酸盐、塑料甚至金)填补牙的空洞即将过时。同时,取代因腐蚀失去的釉质,将是培养生长人的牙釉质。更重要的是,培养生长的釉质蛋白结合在一块的反应,是在病人坐在牙科医生的治疗椅上在口中进行的。这个未来的蓝图是由南加利福尼亚大学牙科学院等组成的研究小组描绘的。最近,他们报告了他们朝着根本改变补牙方向前进的第一步。研究人员应用基因工程技术,首次从活的生物中克隆出为牙釉质编码的基因。此基因是负责生产4种构成牙釉质蛋白质的一种。下一
American dentists believe that cavities filled with the traditional method (such as using silver alloy, silicate, plastic or even gold) is about to become obsolete. At the same time, to replace the enamel lost due to corrosion, will be to cultivate the growth of human enamel. More importantly, the reaction of growing enamel proteins in one piece took place in the mouth of a patient sitting in the dentist's chair. The blueprint for the future is drawn by a team of researchers at the University of Southern California School of Dentistry and others. Recently, they reported the first step toward a fundamental change in their fillings. Using genetic engineering techniques, researchers first cloned genes that code for enamel from living organisms. This gene is responsible for the production of four kinds of composition of enamel protein. Next
