Abstract
This invention discloses an improved dental pulp capping and cavity lining composition which is successful in capping and preserving the vitality of moderately inflammed, as well as normal, healthy dental pulps and also serves as an acid resistant, protective cavity liner. This composition is prepared by reacting suitable phenolic derivatives with formaldehyde or its polymer, under carefully controlled conditions, to form a low molecular weight polymer condensate, which is first purified and then compounded into a two-paste composition of optimized utility. In use, one paste portion, containing the condensate, reacts with the other paste portion, containing calcium hydroxide, to yield after mixing a solid protective layer of set material, which facilitates healing of the pulp and formation of secondary dentin.
