[Biological aspects of endodontics in advanced old age].

Abstract

The traditional rules of endodontics are basing on scientific results and clinical experiences, collected in the first half of our century investigating the teeth of teens and young adults with respect to the epidemiologic situation. Prevention, preserving vitality and teeth have caused a transfer of endodontics in elder persons, but there are other biological conditions, as post-eruptive maturation of enamel, regressive metamorphosis of the pulp, transparency of the dentine of the root, apical apposition of cementum. They are of influence for diagnostic and therapy. Proposals are made.
