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.
