Abstract
A disposable, single chamber ampule is initially provided with a single reactive component, with additional component or components added to the ampule immediately prior to use. The ampule is placed within a capsule, and the capsule is then secured in a holding mechanism of a dental amalgamator for mixing the ingredients. The ampule has flexible wall portions and may be compressed by finger pressure or by use of a dispenser in order to expel the mixed contents directly to an application site.
