Glycogen content and phosphorylase activities in deciduous dental pulp. Study on porcine teeth during root formation,...

Glycogen content and glycogen phosphorylases (a and total) were measured in dental pulps from pigs sacrificed at 20, 40, 50, 70, 90, 120, 180, 270 and 300 days of age. The following conclusions were drawn: (a) pulp glycogen content was higher during root formation than during root resorption; (b) the phosphorylase activities (a and total), were higher during root resorption than in the other phases; (c) pulps from different teeth, when in the same developmental stage, possessed a similar glycogen metabolism, as revealed by glycogen content and enzyme activity determinations.
