SEVEN YEARS.

Fig. 91. 



Seven Years (Figs. 89, 90, 91). — There is nothing special to be seen 

 in front except that the teeth are whiter, — due to the disappearance of 

 "the cement, which has been worn from the surface of the enamel. In 

 profile it is seen that the table of the inferior corner tooth is narrower 

 than that of the superior from the front to behind, so that a notch is 

 formed on the posterior corner of the latter. The incident of the tooth 

 is less perpendicular than at six years. The cups of the tables of the 

 intermediate teeth are wider from in front to behind and narrower from 

 side to side. In the corner teeth the wearing surface is larger and the 

 •cups are smaller. The pincher teeth are oval and the intermediate teeth 

 •commence to become so. In this mouth, again, the superior corner teeth 

 iire fissured on their posterior borders.
