Abstract
Methods for reducing the number and/or size of gas bubbles in a material are disclosed. The disclosed methods involve subjecting materials to pressure for a period of time. The methods have been found to be useful in the preparation of dental composites and dental structures prepared from those composites. Materials produced using the disclosed methods can have enhanced structural and/or aesthetic features.
