Formaldehyde that is active constituent in formocresol used in pulpotomy is known
astoxic agent that causes systemic toxicity.
To determine the fate of the 14C-formaldehyde which was absorbed
following its application to pulpotomy sites, by-pass of posterior facial vein and
cannulation of external carotid artery were established with
14G-polyethylene tube. Blood samples (0.2ml) were collected in glass
syringe before the pulpotomy and then at 0,3, 5, 10, 20, 30, 45, 60, 90 and 120 minutes
there-after. Plasma was separated after centrifugation at 3000xg for 15 min and aliquots
of plasma were counted by liquid scintillation counter.
After liver, kidney, lung, heart, spleen, muscle, and alveolar socket were removed and
solubilized with tissue solubilizer, the radioactivities in solutions were counted by liquid
scintillation counter.
The acute toxicity of formocresol was determined by BUN (Blood Urea Nitrogen), GOT
(Glutamic Oxalacetic Transaminase) and OCT (Ornithine Carbamyl Transferase) assay
in blood samples collected at 0, 2, 4, 6, 9 and 12 hours by means of cardiac puncture.
The results were as follows:
1. The radioactivity of 14C-formaldehyde reached maximal value at 3-5
minutes and decreased thereafter.
2. About 8% of 14C-formaldehyde placed in the pulpotomy site was
actually absorbed systemicauy until 2 hour.
3. About 50% of 14C-formaldehyde absorbed actually was distributed
within 20 minutes.
4. The radioactivity of organ per gram was highest in the spleen and lowest in the
muscle.
5. Total radioactivity of organ was highest in the liver and lowest in the heart.
6. There were no significant differences between control and experimental groups in
BUN, GOT and OCT assay.
