A little more skepticism: > Instead of filling the root canal with artificial materials that may pose bio-compatibility problems Gutta-percha[1] is what is traditionally used to fill the empty canals. It is used because of its bio-compatibility and inertness. The most common complication of a root canal procedure is inadequate cleaning of the canals and related tissues, not bad apical sealing. 1: http://en.wikipedia.org/wiki/Gutta-percha http://en.wikipedia.org/wiki/Gutta-percha
