摘要翻译：
我们建立了一个由酸从牙菌斑扩散到牙釉质引起的龋病进展的理论模型。酸与静态羟基磷灰石反应，导致牙釉质脱矿，从而导致龋病的发展。该模型采用一个静态反应物和一个流动反应物的扩散反应方程组，其中反应项与酸和矿物浓度的乘积成正比。用微扰法近似计算了浓度的变化。将解析近似解与数值解和实验数据进行了比较。

英文摘要：
We develop a theoretical model of the carious lesion progress caused by acids diffusing into the tooth enamel from the dental plaque. The acids react with static hydroxyapatite, which leads to demineralization of the enamel, and consequently to the development of the carious lesion. The model utilizes the diffusion-reaction equations with one static and one mobile reactant where the reaction term is proportional to the product of concentrations of acids and of mineral. The changes of concentrations are calculated approximately by means of a perturbation method. The analytical approximate solutions are compared with the numerical ones and experimental data.
