Abstract
Conclusions
1. Infiltration of 3% calcium gluconate within 8 hours after intense application of hydrofluoric acid caused a significant shortening (about 30%) in healing time and a significant reduction (about 50%) in the incidence of suppuration. The latter cannot alone wholly account for the quicker healing. 2. Multiple treatment at 24-hour intervals is no more effective than a single treatment. 3. Rats appear to show a much quicker and less complicated recovery from severe hydrofluoric acid corrosion than humans. 4. The lesions heal characteristically by granulation under a hard crust.
We are indebted to Professor Torald Sollmann for his important suggestions.
