Purpose: The aim of the work was determine conversion degree of composite dental materials with different resins in relation to different light-curing parameters. Design/methodology/approach: The article provides an insight on factors influencing conversion degree of composite materials. Standardized samples made of Herculite XRV based on a methacrylate resin and Filtek Silorane based on silorane resin and were cured using two types of Light Curing Units (LCUs) – halogen and LED. The samples were cured at different distances and for different times. Findings:Research has showed that the polymerization of Filtek Silorane composite is significantly slower than polymerization of Herculite XRV composite. Extending exposure time does not compensate for decrease of light intensity caused by increase of the distance of the light source from the surface of cured composite. Research limitations/implications: Further studies on degree of conversion of dental composite materials will allow to expand the knowledge on characteristics of materials used in dental clinical practice. Practical implications: Evaluation of curing methods, curing parameters and good knowledge on units used in light-curing of composite materials allow to acquire filling materials with best functional qualities. Originality/value: The paper presents degree of conversion of composite materials based on different matrixes and cured with different methods.
