The Effect of Rotary Instrumentation on the Permeability of Dentin

Journal of Dental Research, 1981
The filtration and diffusion of tritiated water through dentin disks were measured in a split-chamber diffusion cell. The dentin had been cut with a diamond disk and the surfaces modified with a carbide fissure bur or diamond bur. Disks were given a secondary burnishing treatment with a blank bur or a modified blank bur.
