Experimental study of pulpotomy with calcium hydroxide-iodoform paste in dogs' immature permanent teeth.

To investigate the healing process and continuous root development following pulpotomy with improved calcium hydroxide-iodoform paste, the authors performed an experimental study of pulpotomy in immature permanent teeth. Thirty five incompletely formed root canals in dogs were used, and radiographical and histopathological observations were made. The results lead to the conclusion that pulpotomy with improved calcium hydroxide-iodoform paste is a very effective treatment for immature permanent teeth.
