Abstract
The following areas of oral mucosae were examined for the presence and distribution of glycogen, palatal epithelium, epithelium overlying the alveolar processes, dental lamina and outer enamel epithelium and buccal mucosa. Glycogen was observed in all tissues in varying amounts and in a number of different patterns Its presence in the outer enamel epithelium and the dental lamina is particularly discussed. There does not appear to be any relationship in this series between glycogen concentration and keratinization. The lack of any degree of inflammation in these tissues would make it difficult to compare these results with those found formerly in inflamed adult human gingival tissue. There may be a species difference With the exception of the dental lamina, there is a relationship between the amount of glycogen present and the thickness of the epithelium. Age did not appear to influence the glycogen distribution in the palatal and buccal mucosa in this series.
