Abstract

A mixer for mixing a dental composition comprises a mixer housing with a wall of the mixer housing forming a light filter. The light filter provides for substantially blocking light of certain wavelengths, whereas it transmits light of at least some other wavelengths. The invention may help to prevent dental compositions from degrading.
