The purpose of this study was to determine the close relation between clinical symptom and histopathologic finding in pulp. 20 samples of pulp tissue were collected from badly decayed teeth with considerable pulp vitality. Hemogram was also made with the first drop of bleedieg after total pulp extirpation (10cases) and vital pulpotomy(10cases). Histologic specimen was made routinely with extirpated pulp and stained by H&E and P.A.S. Stains. The results under microsopic examination were as follows; 1. Hemogram obtained from dental pulp with acute inflammation revealed increase of polymorphonuclear leukocyte in number, more lymphocytes and monocytes. 2. Hemogram from pulp with chronic inflammation shown the number of lymphocyte and monocyte was remarkably increased. 3. Histologi specimen obtained from teeth with severe clinical symptome showed polymorphonuclear leukocyte infiltration and the hemogram also showed polymorphonuclear leukocytes. 4. Specimen from teeth with moderate symptom showed lymphocyte infiltration and vessel dilatation underneath decayed area. Erythrocytes were massively accumulated inside of the vessel wall.
