A HISTOPATHOLOGIC STUDY ON THE PULPAL RESPONSE IN DOGS AFTER PULPOTOMY WITH FERRIC SULFATE
 
Abstract
The purpose of this study was to compare the effect of ferric sulfate and formocresol as pulp dressing agents in pulpotomized teeth of dogs. 40 teeth of 5 dogs, weighting 10kg. were used in this study. The animals were sacrificed at the intervals of 3, 7, 14, 28 and 56 days for histopathologic evaluation. The specimens were observed by the light microscope. The results were as follows : 1. Inflammatory response was observed in both groups, but pulp tissue of ferric sulfate group was showed lesser inflammatory degree and more rapid recovery than that of formocresol group. 2. In ferric sulfate group odontoblasts showed irregular arrangement pattern at initial stage and returned to regular pattern after 2 weeks. But in formocresol group. continued irregular pattern of odontoblast was observed during experimental period. 3. Reparative dentin was produced widely along the canal in one specimen of formocresol group at 8 weeks and dentinal bridge was formed in two specimens of ferric sulfate group at 8 weeks.
Key Words: Ferric sulfate, Formocresol, Pulpotomy, Pulpal response
