Abstract
The light-initiated process plays an increasingly important role in biomedical applications for the production of photocurable dental fillings. The use of photochemically initiated polymerization to obtain dental composites enables the use of unique and innovative features of this method. The most important are: short curing time of the composition (up to a few seconds); carrying out the reaction at room temperature; low energy consumption, spatial resolution (polymerization only in the exposed areas). Nevertheless, many different factors, such as the selection of appropriate monomers, initiators, inorganic fillers, curing time, type of radiation and light power, influence the quality of the composite obtained. In this work, influence of different factors such as weight ratio of BisGMA and TEGDMA monomers, amine concentration, type of amine, type of diode on properties of standard dental light-cure composite resins were studied. Completely new, safe initiating systems intended for the production of a new generation of dental composites polymerizing via cationic mechanism, characterized by reduced polymerization shrinkage were also presented. Conversion rates were investigated using the Real-Time FT-IR technique. The article shows that the highest conversion rates were obtained for a dental composition composed of camphorquinone (CQ) and ethyl 4-(dimethylamino)benzoate (EDB) in molar ratio 1: 2 and bisphenol A-glycidyl methacrylate (BisGMA) and triethylene glycol dimethacrylate (TEGDMA) monomers in weight ratio 7: 3.
