This study was undertaken to evaluate the pulpal responses to the intermediate
restorative materials such as Zinc phosphate cement, Polycarboxylate cement, IRM(zinc
oxide eugenol cement), Dycal, Life, Cresatin, and Fluoride in caivties which were cut
with high speed instrument. 5 dogs were used as experimental animals and devided into
8 groups. The internals of observa-observation ranged 3 days, 1, 3, 4, 8 weeks after
experiment respectively. The specimens were fixed with 10% formalin and decalcified in
5% nitric acid. All slides were stained with hemtoxylin-eosin and examined
histopathologically. The results were as follows:
1. In control group, severe vacuolar degeneration and atrophy of odontoblasts were seen
in 3 days, hemorrhage and congestion continued until 8 weeks. Necrosis of odontoblastic
layer was seen in zinc phosphate cement group and polycarboxylate cement group.
2, In dycal group, vacuolar degeneration and atrophy of odontoblast were not seen, but
in Life group, these were seen in 3 days and partially continued until 3 weeks. In 4
weeks, regeneration of odontoblast was occurred.
3. In Cresatin group, there was no pathosis except odontoblastic displacement. In
Fluoride group, vacuolar degeneration of odontoblast was seen and soon disappeared. As
compared with control group, pathological change of the pulp tissue in experimental
group were decreased after amalgam restoration.
