| Abstract ： | [Abstract] Forty-five male rats of five weeks of age which were operated upon to induce pulmonary emphysema and 51 non-operated rats were examined histologically. The rats which were experimentally induced to develop pulmonary emphysema and whose blood pH was acidic were sacrificed 56 days after the operation. In their molars, pulp stones were found in a considerably high incidence. The pulp stones were examined histologicaly, histochemically and their hardness compared with that of secondary dentin. They not only resembled those of the human, but also revealed variant stages of development. They were classified into five groups : 1) Pulp stone surrounded by odontoblasts, 2) pulp stone with necrotic pulp cells, 3) pulp stone with degenerated or necrotic epithelial cells, 4) pulp stone with a necrotic blood vessel, and 5) amorphous calcified deposits. The developmental mechanism, the histological and histochemical properties of the pulp stones and of the amorphous calcified deposits were discussed. |
