Dielectric analysis of depth dependent curing behavior of dental resin composites

Popis výsledku v původním jazyce

Objectives The aim of this study is to investigate depth dependent changes of polymerization process and kinetics of visible light-curing (VLC) dental composites in real-time. The measured quantity - "ion viscosity" determined by dielectric analysis (DEA)-provides the depth dependent reaction rate which is correlated to the light intensity available in the corresponding depths derived from light transmission measurements. Methods The ion viscosity curves of two composites (VOCO Arabesk Top and Grandio)were determined during irradiation of 40 s with a light-curing unit (LCU) in specimen depths of 0.5/0.75/1.0/1.25/1.5/1.75 and 2.0 mm using a dielectric cure analyzer (NETZSCH DEA 231 with Mini IDEX sensors). The thickness dependent light transmission was measured by irradiation composite specimens of various thicknesses on top of a radiometer setup. Results The shape of the ion viscosity curves depends strongly on the specimen thickness above the sensor. All curves exhibit a range of li
