Abstract
Knoop hardness was correlated to degree of conversion (DC) of carbon double bonds, determined by IR, during the setting reaction of three unfilled dental resins. For a specific resin, increase in hardness correlates well with increases in DC during setting. However, an absolute hardness number cannot be used to predict a DC when comparing different resins. The two techniques for determining extent of cure in dental resins cannot always be used interchangeably, since each is sensitive to different variables.
