Abstract
Artificial carious lesions were produced in human enamel using lactic acid [HL] buffers plus diphosphonate [MHDP]. Surface layer thickness was related to [MHDP], middle zone (body) and inner zone depths to [HL] and pH. Indications are that diffusion in enamel is predominantly by unionised species such as HL and CaHPO4, and dissolution by H+ and L-.
摘要
使用乳酸[HL]缓冲液加双膦酸盐[MHDP]在人牙釉质中制造人工龋损。表层厚度与[MHDP]有关，中间区（主体）和内层深度与[HL]及pH值有关。有迹象表明，牙釉质中的扩散主要通过HL和CaHPO4等非离子化物质进行，而溶解则由H⁺和L⁻引起。
