Real‐Time Kinetic Monitoring of Dental Composite Photopolymerization by Photo‐DSC

open access: yesJournal of Applied Polymer Science, EarlyView.
Real time photo‐DSC was used to investigate polymerization kinetics of Bis‐GMA/TEGDMA dental composites. The study thoroughly examines how photo‐initiator type, concentration, silica filler content, and moisture affect conversion and curing rate. Results highlight optimal initiator systems, filler effects, and moisture tolerance, providing valuable ...
