摘要：

The diffusion characteristics of dental plaque from four different subjects were examined. An estimate of the diffusion coefficient of radioactive xenon gas, 133Xe, in plaque was found by monitoring the clearance of this gas from a thin layer of plaque. The mean value for the diffusion coefficient, ± standard error, was (7.2 ± 0.2) × 10-6cm2 s-1, with no apparent subject-to-subject variation. It is concluded that plaque does not present a significant physical barrier to the diffusion of small uncharged species. © 1979.
