Progressive decrease in dentine permeability following cavity preparation.
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.
