Résumé

The present study was conducted to determine the association between parathyroid hormone 1-34 administration and ectopic calcification in rats with glucocorticoid induced osteoporosis. A total of 18 rats were used in the current study. Osteoporosis was induced in all rats via dexamethasone administration, then rats were randomly distributed into Control and Forteo groups and were sacrificed 4 weeks after initiation of drug administration. Hemi-mandibles were decalcified followed by routine histological analysis. Among the Forteo group rats, three rats displayed the presence of ectopic calcification. True pulp stone, intra-pulpal calcified structure with entrapped cells and intra periodontal bone-like calcified structure with entrapped cells were observed while no ectopic calcification was noticed in the control group.
