Abstract

Thermosetting dental materials which contain a peroxycarboxylic acid in addition to other components customarily contained in dental materials and in addition to at least one monomeric ester of methacrylic acid as polymerization catalyst. These dental materials are distinguished from those which contain an organic peroxide as polymerization catalyst by a distinctly better stability during storage.
