  • FLAVONOID DERIVATIVE FOR TREATING DENTAL CARIES
    Publication number: 20220281903
    Abstract: The invention relates to a flavonoid derivative containing a flavonoid that is coupled to an alkylene group via an ether bond, said alkylene group having an adhesion group for adhesion onto a dental surface. The flavonoid derivative has a long-term suppressing effect on the dental disease-causing formation of biofilm on the dental surfaces treated with the flavonoid derivative. The invention further relates to a kit for producing such a flavonoid derivative, and to the use of same.

  • Radically polymerizable compound
    Patent number: 10633491
    Abstract: The invention provides a radically polymerizable compound wherein an acid group is joined via a spacer group to a polyethyleneimine group. The polyethyleneimine group has at least one radically polymerizable group in the side chain and/or terminally. The invention relates further to a process for preparing such compounds by cationic polymerization of oxazolines, to the use of such compounds as constituents of a dental material, and to a dental material comprising the compounds of the invention.
