Impact of Orthodontic Adhesive Magnets on Degree of Conversion and the kinetics of polymerization

Abstract

The purpose of this study was to investigate the effects of storing uncured photopolymerized dental adhesive in a magnetic field on their kinetics of polymerization and degree of conversion (DC%). Method: Vage Ortho Uv orthodontic adhesive was used in this experiment. Under constant frequency (50Hz), the applied magnetic field was used at two different intensities (fixed at 0.01T and 0.05T) for 5 minutes each. Using Fourier transform infrared spectroscopy (FTIR-ATR), the degree of conversion (DC%) and polymerization kinetics were assessed. Results: There was a clear improvement in the results when compared to the control, the DC% mean tends to increase as MF increases starting at 0.05T. Conclusions: The DC% of the Vega ortho Uv assessed orthodontic adhesive is influenced by the MF. Uncured orthodontic adhesive that has been exposed to MF for five minutes improves the changed bond angles or causes bond elongations, both of which would cause molecular deformation.
