Formocresol pulpotomy in teeth of dogs with induced pulpal and periapical pathosesKennedy, David B., 1946- January 1971 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Formocresol pulpotomy has been recommended for all infected primary
molars irrespective of pulp vitality. Microscopic evidence is lacking
when teeth with less than optimal pulpal preoperative conditions are
treated. This study evaluated clinically, radiographically, and microscopically
the effect of the five-minute formocresol pulpotomy in primary
and permanent teeth of dogs with induced pulpal and periapical
pathoses.
Radicular pulps of 18 permanent and 12 primary teeth were exposed
to the oral flora for 28 and 14 days, respectively, to produce pathoses
that would contraindicate routine use of the pulpotomy. The five-minute
formocresol pulpotomy was performed and nine permanent teeth were evaluated
after four weeks and another nine after 12 weeks; the primary teeth
were evaluated after 14 days. Eight permanent and four primary "control”
teeth had their radicular pulps exposed to the oral flora for identical
periods but were not treated by formocresol.
In permanent teeth clinical success was 90 per cent, radiographic
success was 30 per cent, and microscopic success of bloc sections was
10 per cent. The vital pulp reacted to formocresol by forming a homogenous
band of markedly eosinophilic tissue, interpreted as "fixation;"
very pale staining tissue was apical to this. A second area of marked
eosinophilic tissue was in the apical part of all vital canals, apical
to which was vital normal pulp. Similar trends were seen in the primary
teeth.
No "fixation," organization or repair was seen within any periapical
lesion. The microscopic periapical appearance of related vital
permanent and all necrotic canals indicated that formocresol pulpotomy
is not particularly effective in teeth with induced pulpal and periapical
pathoses. The findings suggest that it be used only under optimal
clinical conditions.

Comparison of electrosurgical and formocresol pulpotomy proceduresFulkerson, Bradley Todd January 1997 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Formocresol is the most commonly used pharmacologic pulpotomy agent.
Concerns over its safety have led investigators to search for new pulpotomy
medicaments. This study compared the electrosurgical pulpotomy with the
formocresol pulpotomy in teeth requiring pulp therapy after carious
involvement. There were 25 pulpotomies performed in each group. The teeth
were evaluated for clinical and radiographic success after at least six months. In
the electrosurgical group, the clinical and radiographic success rates were 96
percent and 84 percent, respectively. The age range at the time of treatment was
26 to 97 months, with a mean treatment age of 63.6 months. The postoperative
observation time range was six to 31 months, with the mean being 10.9 months.
In the formocresol group, the clinical and radiographic success rates were 100
percent and 92 percent, respectively. The age range at the time of treatment was
32 to 126 months, with a mean treatment age of 68.2 months. The postoperative
observation time ranged from five to 25 months, with the mean being 11.5
months. The electrosurgical and forrnocresol groups were compared for
differences in the percentage of successes by using a Fisher's Exact test. There
were no statistical differences between the two groups at the p < 0.05 level.
Therefore, this study failed to demonstrate a statistically significant difference in
the success rate between the electrosurgical and formocresol pulpotomy
techniques and supports the use of the electrosurgical pulpotomy as a viable and
safe alternative to formocresol.
