Fig. 7. Longitudinal Section of a Molar Tooth of Man. 

 ( SOBOTTA. ) 



X 8. 



The figure gives a general view of the structure of the tooth. The pulp 

 cavity is not cut its whole length in the two roots seen in the section. -We 

 recognize the three main elements of the tooth dentine, enamel, and cemen- 

 tum and their division into crown and root. On account of the low magnifica- 

 tion, the interglobular spaces appear only as a dark zone on the surface of the 

 dentine. C, Cementum. D, Dentine, P, Pulp cavity. S, Enamel.
