The purpose of this study was to contrast histopathologically the pulp response to
formocresol with electrosurgical pulpotomy. Upper and lower teeth in three dogs, aged
about 1 year, were subjected to mechanical pulp amputations and were divided into two
groups, pulpotomized with formocresol and momentary electrosurgical exposure.
The experimental animals were sacrificed at 3 days, 2 weeks, 6 weeks postoperatively,
sections were obtained and observed with light microscope.
The results were as follows.
1. In the formocresol groups, pulp tissue responses showed inflammation and atrophy
of odontoblast confined to subjacent to amputation site and reparative dentin was formed
in 6-week group.
2. In the electrosurgical groups, inflammatory zone was decreased with time elapsed
and reparative dentin was formed in 6-week group.
3. Electrosurgical pulpotomy exibited no significant difference with formocresol
histopathologically and almost typical morphology of pulp tissue for the time studied.
