[Do root canal filling materials enter dentin tubules?].
After removal of the smear layer all root filling materials tested were able to infiltrate dentin tubules. With the cement types studied, filled dentin tubules were found even at a distance of 100 microns from the root canal. The infiltration of the dentin tubules now explains the outstanding results of pigment penetration tests. The question, if the smear layer is to be removed or not, can now be answered "yes".
