Abstract

Dental compositions and disulfide monomers are described. The disulfide monomer comprise a disulfide backbone group wherein each of the sulfur atoms are bonded to an ethylenically unsaturated group via a divalent linking group and the linking group comprises at least one heteroatom; and at least one other monomer ethylenically unsaturated monomer.
