Five Years (Figs. 83, 84, 85). — The mouth is entirely made ; all of 

 the permanent teeth have reached the same level in both jaws. The jaws 

 are convex in both directions ; the tush teeth have completed their 

 eruption. The corner teeth have commenced to wear on their anterior 

 border; the pincher teeth are leveled, but the cups are still elongated 

 from side to side and are ver}^ narrow ; they commence to approach to 

 the posterior border of the teeth. This form of cup indicates that in 

 these teeth the cups are very shallow. The incisive arches form a regular 

 half-circle.
