摘要
1990年黄力子提出了“龋病发病机理的生物电化学理论”,认为龋病的发生和发展主要是一种电化学腐蚀过程。本研究为验证此理论,将离体牙置于电解池中以观察对比电解池阴、阳极的氧化还原反应对牙齿脱矿的不同影响。结果表明电解池阳极的氧化反应能促进牙齿脱矿,使接触阳极的牙齿开窗区形成深达牙本质的类龋洞;电解池阴极的还原反应能够抑制牙齿脱矿,接触阴极的牙齿开窗区表面完整。电化学人工龋模型的成功为“龋病发病机理的生物电化学理论”提供了直接的实验证据。
Based on the results of clinical experiment, combined with modern electrochemical theory, Huang Lizi put forward the bioelectrochemical theory of pathogenesis of dental caries in 1990. The new theory suggested that the occourrence and development of dental caries were not the dissolution of teeth in acids but a process of electrochemical corrosion. In order to test the new theory, intact and caries -free teeth were immersed into electrolytic cell. Results: the oxidation of anode could promote dental demineralization and formation of caries -like cavities with lesions deep into dentin at exposed areas while the reduction of cathode could inhibit demineralization and the surfaces of teeth at exposed areas were intact. Hence, the results of this study provided Bio-electrochemical theory with direct experment evidences.
