Abstract:
It is known that high levels of residual monomer have a deleterious effect on the properties of denture base polymers and may cause irritation or hypersensitivity of the oral tissues. In the present study variations in determination methodology and their influence on residual monomer levels are evaluated. The results demonstrate that filtration of the sample, sealed storage and incorporation of an appropriate volume of internal standard enhanced the accuracy of the technique.
