| ABSTRACTBack Ground: Pulpal changes represented by cell renewal and ground substance formation and deposition ofspecific tissue was studied in replanted teeth. The aim of the study was to evaluate pulp response of replantedimmature teeth.Materials and Methods: Fifteen rats of 3 days old aged was subjected to replantation process of upper 1st molar. Theywere scarified after 7 days of replantation for histological analysis by Hematoxyline and Eosin stain and forhistochemical investigation by PAS stain.Results: There was a growth in replanted tooth germ (experimental group) in 12 of the 15 rats.The teeth showed well organized and well vascularized pulp tissue with regenerative potential response was seen inpulp by apposition of newly ground substance detected by histochemical PAS stain. Other 3 rats showeddegeneration of replanted tooth germ. Control rats group failed to show apposition of acid mucopolysaccharides asthe experimental one.Conclusion: Regenerative response for pulp cells recognized by well apposition of acid mucopolysacchridessubstance in pulp tissue of replanted immature rat tooth.Keywords: Cell, pulp, rat.
