[Experimental studies of the size of the root surface of permanent human teeth].

Abstract

The surface of 173 of right maxillary and mandibular teeth were investigated by electron paramagnetic resonance technique. After particular preparation of the teeth the surface of their roots was covered with a layer of marker substance, before freezing them in liquid nitrogen. Resonance spectra were recorded under special standard conditions with an estimated error of 7% for the measurements. The method presented in this paper proved to be suitable for measuring the largeness of the surface of the root of human teeth and can find further application for solving other problems in descriptive anatomy.
