Abstract
This invention relates to dental restorative materials and adhesives, and particularly relates to the control of chemical reactions in chemically initiated dental restorative materials. The invention includes a method for controllably affecting the reaction of a chemiclly initiated liquid dental adhesive, resin or restorative material comprising mixing the adhesive, resin or retorative material with an instrument, or in a mixing container, at least a portion of which instrument or container has been impregnated with a reaction affecting compound of predetermined amount to accomplish the intended reaction effect. Devices and kits for use in the inventive methods are also disclosed. The present invention affords both efficiency and greater control in applying dental adhesives, resins or restorative materials, reduces the time necessary for mixing and dispensing solutions and allows the components of the dental adhesive, resin or retorative material to be stored in a more stable form.
