The third molars generally make their appearance between the ages of sixteen and twenty. The final development of the length of the maxillæ posterior to the mental foramen in the lower jaw and maxillary sinus in the upper, takes place during this period, and in this manner sufficient space is provided for the proper alignment of the third molar when it breaks through the gum tissue. When this development proceeds without any disturbing constitutional causes, no difficulties attend the eruption of these teeth. As, however, all inflammatory actions that arise during this period either from local pathologic causes or by virtue of constitutional disturbances, have a marked effect on the osseous development of these parts we find the normal type of development to be the exception. These departures from a purely normal type vary greatly according to the amount of disturbance that has taken place, and in a large number
