One would think that when teeth affected by periodontal disease are extracted there would be some difficulties with healing. Quite the contrary, sockets developed good blood clots and healed rapidly, without pain or the development of a dry socket.

It should be more apparent now that the cases mentioned involve two distinct types of individuals. This was borne out even more dramatically when two different types of extraction sockets were examined under a microscope. Here, too, the disparity proved so definite as to be of diagnostic value.

Sockets of teeth extracted for root end infections when condensing osteitis was present had only a few white blood cells(leucocytes) and granules,but large numbers of organisms outside these cells.

Dentists looked upon pyorrhea as being primarily an infectious disease at the time of the Price studies, and many still do today. You can see from the data that, although bacteria are present, pyorrhea is not due to a specific infection but, rather, involves definite systemic body conditions. The factors were found to be related to a person's specific susceptibility and biological inheritance; that is, they are connected in a very difinite way to one's own biological defense and ability of the immune system.
