Abstract
The differences between the periodontiums of hibernat- and
non-hibernating 13-lined ground squirrels were determined.
Maxillas were removed, embedded in paraffine, sectioned
and stained with hemotoxylin and eosin. While the active
squirrel presented a "typical" periodontium structure, the
hibernating animals presented structures that were "atypical".
The hibernating animals did not illustrate the characteristic
wedge-shaped appearance of the gingiva and the
surface epithelium grew extensively down the root of the
tooth. The width of the periodontal membrane at the furcation
was drastically wider in the hibernating squirrels;
this is noted along with a loss in height of the interradicular
bone. The cementum of the hibernating squirrels was
much wider in comparison to the non-hibernating animal.
These differences provide the basic picture needed in order
to further research in the field of hibernation.
