Arteriosclerotic changes within the diabetic oral vasculature.

Microscopic sections of diabetic, arteriosclerotic nondiabetic, and nondiabetic nonarteriosclerotic human palate were qualitatively evaluated for small artery colloidal-iron-positive, acid mucopolysaccharide content. The association of abnormal colloidal-iron-positive material with structural detail in the arterial wall was clarified by comparison with specimens of amputated diabetic human legs.
