Alginate impressions of an acrylic study cast pair were disinfected to a variety of regimes using 2.2 per cent glutaraldehyde. A number of linear measurements on the resultant plaster study casts were made using a Reflex Plotter to assess the effect on the dimensional stability of the casts. Significant differences were found for a number of the variables measured. Quantitatively these differences were small and of limited clinical significance; they may, however, be of greater significance where serial records are being collected for research.
