The effect of calcitonin in vitro on tooth germs in protein-energy malnourished rats.

The effect of calcitonin on the development of incisor and molar tooth germs was studied in normal and nutritionally deprived newborn rats. Calcitonin affected the calcium uptake of nutritionally deprived molar tooth germs in the early postnatal period; this interaction was not seen in the later postnatal period, however.
