The physical and mechanical properties of most polymeric materials are dependent upon the extent of the reaction which converts monomer to polymer. This premise has led to the use of mechanical properties tests, such as hardness, transverse and tensile strength, as indirect methods for determining the degree of conversion in dental restorative resins. However, the correlation between properties and the conversion reaction becomes somewhat clouded when considering the cross-linked, network-forming polymers used in these dental resins. The properties of these systems are very likely dependent upon the quality of the network formed, as well as the concentration of residual unreacted species. The purpose of this study was to determine the nature of the correlation between the degree of conversion and the micro-hardness of unfilled dental restorative resins. An attempt was also made to compare the time frames between conversion and the acquisition of maximum hardness in these quick-setting resins.
