[3-D reconstruction of a tooth germ with hereditary opalescent dentine].

Abstract

A computer-aided three-dimensional reconstruction of a tooth-germ with hereditary opalescent dentine for the first time permitted to delineate the characteristic large dentinal canals as being of canal-like shape and to show their spatial relationship to the dentinal contour. The tubules often displayed links to pulpal tissue and extended from pulpo-dentinal junction up to the outer layer of dentine. The results of this study support the hypothesis of a vasal origin of these tubules.
