Effect of Testosterone Propionate on Permanent Canine Tooth Eruption in the Monkey (Macaca mulatta).

Conclusions

A study of Table I reveals that in no normal male were the 4 permanent canines recorded as having emerged more or less simultaneously. The average age of the injected animals at time of canine emergence is seen to be about a year earlier than that of the controls. In fact, the earliest permanent canines in the latter group did not appear as early as the latest ones in the experimental group. It is thus evident that when androgen is employed as a growth-stimulating agent, the development with emergence of the canine teeth is also accelerated.
