[Metric recording of color changes in filling materials].
A new test arrangement for metric recording of color changes is described. Its usability is demonstrated by measurements made in test specimens of composite filling materials. Measurable differences were observed with both the original color and "yellowing" after irradiation. The color changes are visible with the naked eye, but objective comparison is possible by metric determination only.
