Summary Tooth germs from foetal rats of 17 days post-insemination were maintained in vitro for 12 days. Odontoblasts and ameloblasts differentiated and secreted their respective matrices in which mineralization occurred. The ultrastructure of the cells was qualitatively similar to that observed in normal development. Odontoblasts contained more lysosome-like bodies and were found to degenerate in some sites. Mantle dentine was formed but few von Korff fibres were observed. Calcospherites were rarely seen and the mineralizing front of dentine was predominantly linear, associated with numerous small early foci of mineral formation. Enamel showed prism formation associated with the Tomes' process of the ameloblast but some local disturbances in the pattern of enamel formation were observed.
