The solubility and disintegration of some dental luting cements.

Available technical methods do not permit the fabri­ cation of dental restorations outside the mouth which will not expose the cementing medium to the influence of the oral fluids. Although meticulous craftsmanship may attain very high standards of marginal adap­ tation in such restorations the solubility and disinte­ gration of cementing media is still considered suffi­ ciently important to warrant the inclusion of tests of these characteristics in standards specifications for ce­ ments. For this reason it was considered that a com­ parison of the solubility and disintegration of some of the luting cements which have been marketed fairly re­ cently would be of interest.
