Effect of different polymerization devices on the degree of conversion and the physical properties of an indirect resin composite.

Polymerization of indirect resin composites (IRC) is carried out in the 'laboratories using special photo-polymerization devices to achieve a higher degree of conversion (DC). Such devices present variation in chambers and light output which may have consequences on the chemical and physical properties of IRCs. This study evaluated the effect of different polymerization devices on the flexural strength, Vickers microhardness and DC of an IRC.
