Immune Neutrality of Calf Skin Collagen Gel Used to Stimulate Revitalization in Pulpless Open Apex Teeth of Rhesus Monkeys

A collagen mineral gel has recently been shown to stimulate revitalization of pulpless open apex teeth when syringed into debrided root canals. Experiments were conducted to examine possible stimulation of the immune system by the experimental procedure. Ring tests (interface precipitation analysis), Ouchterlony plates and hemagglutination tests on plasma samples taken from experimental rhesus monkeys throughout the healing process indicate a complete lack of humoral immune responsiveness to the injected collagen.
