the odontoblasts into the dentine tubules. The papillary tissue 

 is embryonic connective tissue in which capillaries and nerves 

 ramify. After the crown of the tooth has been completed, the 

 fang is produced in a like manner, but without enamel. 



The space required for the enlarging tooth is provided by 

 the growth of the jaw and the concurrent removal of osseous 

 material on the inner aspect of the alveolar cavity by the 

 osteoclasts, a number of which are observable upon the alveolar 

 tissue around. 



The dental germ for the permanent or secondary tooth occurs 

 as a small lateral offset from the strand of epithelial material 

 (.gubernaculum), which still connects the enamel organ with 

 the epithelium of the gum.
