Abstract

A comparison was made between the rate of iodide permeation of dentin by diffusion and by filtration. Before acid etching, filtration only doubled the rate of iodide permeation relative to that obtained by diffusion. After acid etching, filtration produced a 32-fold increase in permeation. Acid etching, by removing occluding debris, facilitates filtration more than diffusion.

摘要

对牙本质中碘化物通过扩散和过滤的渗透速率进行了比较。在酸蚀之前，相对于通过扩散获得的速率，过滤仅使碘化物的渗透速率增加了一倍。酸蚀后，过滤使渗透率提高了32倍。酸蚀通过去除阻塞性碎屑，比扩散更有利于过滤。
