Abstract EN
Specular reflectance Fourier transform infrared (SR-FTIR) spectroscopy was used to study the setting reaction of dental resin-modified glass ionomer (RMGI) restoratives as a function of curing depth and postirradiation time.
Two light-cure and one tri-cure RMGI materials were selected and used according to the manufacturers’ instructions.
Samples were prepared by filling the mixed materials into custom-made molds and then light-irradiating using a dental curing light.
The degree of conversion and the extent of acid-base reaction of the materials at different depths (0, 1, 2, and 4 mm) and postirradiation times (10 min, 1 day, and 7 days) were determined using SR-FTIR spectroscopy in conjunction with the Kramers-Kronig (K-K) transformation.
The setting reaction was also investigated using microhardness measurements.
The results showed that the depth of cure increased over time by the continuous acid-base reaction rather than photopolymerization or chemical polymerization.
Microhardness tests seemed less suitable for studying the setting reaction as a function of postirradiation time, probably due to softening from the humidity.
Analysis using specular reflectance in conjunction with the K-K algorithm was an easy and effective method for monitoring the setting reaction of dental RMGI materials.
