Abstract The water absorption of a dental silicate cement was measured both in de-ionized water and in pH controlled phosphate buffers of several ionic strengths. Uptake is found to be related to ionic strength. Water loss was studied using thermogravimetry. Water loss is seen to be a continuous process from ambient temperatures to in excess of 500° C. The implications of the findings are considered not only from a clinical viewpoint but also in relation to past reports of solubility of this material which were uncorrected for water uptake. The usefulness of the concepts of “evaporable” and “non-evaporable” water are considered and the results are examined to assess the importance of drying temperature in carrying out solubility measurements.
