title: [Functional morphology of the odontoblast cell].
abstract: The most highly differentiated cells of the dental pulp - odontoblasts, taken from normal and carious teeth of persons of various age groups were investigated by the aid of electron microscope. Aim of the investigation to determine the relationship between the fine structure and function. Ultrastructural investigation shows that odontoblasts beside the 1) production of dentin take part in the 2) transport of substances and 3) tissue fluids. In the beginning and continuous promoting of the 4) crystallization of the enamel layers odontoblasts play a role of a border-surface which provide a necessary concentration 5) On the end part of nerve fibres they may function as supporting cells (replacement of the Schwann-cells). 6) When pathological processes present (caries) the ultrastructure shows cell-activity of defence type.
