The cause for regression of hypersensitivity has not yet been fully elucidated. We have established a method to measure quantitatively dentin permeability, and to analyze the time-based effect of hypersensitivity. The gradual relief of hypersensitivity with time was analyzed by morphological analysis of the dentin slices and measurement of their permeability. Crystal deposition in orifices of dentinal tubules was evident. Even small particle size crystallites not completely obturating dentinal tubules, have a major effect on reduction of permeability. The concentration of hydroxyethyl methacrylate affects the permeability of resin-based material for hypersensitivity. The structure and volume of the internal crystal varies depending on the stock solution in calcium phosphate-based material.

超敏反应消退的原因尚未完全阐明。我们已经建立了一种定量测量牙本质渗透性的方法，并分析了超敏反应的时间效应。通过对牙本质切片的形态分析和渗透性测定，分析牙本质过敏症随时间逐渐减轻的情况。牙本质小管口有明显的晶体沉积。即使是小颗粒的微晶不能完全封闭牙本质小管，对降低渗透性也有很大的作用。甲基丙烯酸羟乙酯的浓度影响树脂基材料的感光渗透性。内部晶体的结构和体积因磷酸钙基材料中的原料溶液而异。
