The present invention is preferably directed to a dispenser of the type sold by 3M ESPE under the trade name Pentamix and as also described above. Such a dispenser preferably comprises at least a first and a second compartment for a first reservoir and a second reservoir, respectively, the first and the second reservoirs containing a first and a second component for the dental material, respectively. It further preferably comprises a first and a second plunger driven by a first drive for advancing the first and the second components from the first and the second reservoirs, respectively. Moreover, a dynamic mixer driven by a second drive for automatically mixing the first and second components to form the dental material from the first and second components is provided. Such a dispenser further preferably has a dispensing portion or mixing tip for dispensing the mixed dental material. The present invention is more particularly directed to a dispenser or method adapted for advancing and mixing at least one dental material, comprising at least one drive which is operated on a predetermined, non-uniform drive speed profile. Preferably an advancing speed profile is provided for advancing the components and/or a mixing speed profile is provided for mixing the components, and either profile may be a 'drive speed profile' as that term is used herein. More preferably both profiles are provided.
