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.
