Effects of radiant exposure values using second and third generation light curing units on the degree of conversion of a lucirin-based resin composite

摘要

Alternative photoinitiators with different absorption wavelengths have been used in resin composites (RCs), so it is crucial to evaluate the effectiveness of light-curing units (LCUs) on these products. Objective Using Fourier transform infrared analysis (FTIR) in vitro, the effects of varying radiant exposure (RE) values generated by second and third generation LED LCUs on the degree of conversion (DC) and maximum rate of polymerization (Rp^max) of an experimental Lucirin TPO-based RC were evaluated.
