The inductive properties of human dentin and cementum.

Studies of the inductive properties of human dentin and cementum have yielded differing results. Comparisons are difficult to draw because of variations in time, donor tissue, host immunologic status, implant site, decalcifying agents and degree of decalcification. Analysis of the many experiments intimates that the answers may lie in the use of citric acid and/or the degree of decalcification. The direction of future investigations is suggested.
