The present investigation examined the activities of various enzymes associated with the carbohydrate metabolism in different phases of root development of swine deciduous dental pulps. The data showed that the potential carbohydrate metabolizing capacity of pulpal tissue was greatest in the root forming phase (two months). However, when compared with samples taken from the fully formed root (six months), a higher activity of glucose-6-phosphate dehydrogenase and lactate dehydrogenase was found in samples taken from the root resorption phase (nine months).
