Dentine permeability determinations were made longitudinally in cavities prepared in dog teeth in vivo, using two different techniques: isotope clearance and fluid filtration. Measurements made with both techniques indicate that there is a large reduction in dentine-permeability within the first week following cavity preparation. The phenomenon requires an intact pulp and is not the result of microleakage of temporary restorations.
在体内对犬齿制备的窝洞进行纵向牙本质渗透性测定，采用两种不同技术：同位素清除法和流体过滤法。两种技术的测量结果均表明，窝洞制备后的第一周内牙本质渗透性大幅降低。这种现象需要完整的牙髓，并非临时修复体微渗漏的结果。
