The author studied histopathologically on the influence of sweets to the process of healing and dentin bridge formation on the amputated pulp of dog´s teeth. Calcium hydroxide mixed with 10% and 30% solutions of several sweets were applied on the surface of amputated pulp as irritants.
The results were as follows.
1. Dentin bridge began to form at 1st week after pulpotomy in most of the cases, but the cases of 10% solutions of maltose, 10% and 30% solutions of saccharin mixed with calcium hydroxide formed at 2nd week.
2. Eosinophilic homogenous substances appeared under the area of amputated pulp, and the substances j were replaced with the structures of dentin bridge.
3. The odontoblasts under the dentin bridge were round or spindle shape, and arranged in parallel or stratified to the dentin bridge at 1st week. But the palisade arrangement of columnar odontoblasts was found on the border between the dentin bridge and the root canal walls.
4. All of the cases showed mild inflammatory changes at 1st week after pulpotomy, and the changes were disappeared gradually.
5. Vacuolization in the odontoblastic layer was found in the cases of using 30% solutions of fructose, 10 and 30% solutions of lactose, and proliferation of fibroblasts, in the cases of using 30% solutions of maltose, 10% and 30% solutions of saccharin, and reticular atrophy, in the cases of 30% solutions of saccharin.
6. The formation of the secondary dentin was more prominent at 2nd week after pulpotomy.
7. The amputated area was composed of the blood clots layer, atrophic or necrotic pulp tissue layer and vital pulp tissue. The atrophic pulp tissue under the blood clots layer were gradually changed to myxomatous changes or liquefaction necrosis.
