  • Patent number: 9522099
    Abstract: A self-cure, dual-cure or tri-cure polymerizable dental composition is provided with at least one functional chemical. The dental composition is divided into a three-part composition to avoid stability issues caused by degradation and/or loss of function of one component in the extended presence of another component, and the three parts are packaged in a tri-barrel syringe or cartridge delivery system to avoid premature chemical interaction between the functional chemical, redox initiator and/or acid/base.

    Assignee: Kerr Corporation
    Inventors: Xuejun Qian, David Tobia
  • Patent number: 9399004
    Abstract: A self-cure or dual-cure polymerizable dental composition is provided with a redox indicator. The composition exhibits an initial first color upon mixing of the two parts and then changes to a second color that is noticeably different from the first color during the curing or polymerization of the composition initiated through the redox initiator system. Advantageously, the first color may be distinctively different from tooth structure and can be easily noticed. The second color may be essentially colorless, a neutral color, or a non-visually observable color in reference to the tooth structure.
