Light-curing dental resin-based composites: How it works and how you can make it work

Aim Clinicians may become quite familiar with the rapid transformation of composite pastes to rigid solids, as a routine phenomenon in operative dentistry. But they still lack scientific understanding how and why this happens. Efforts learn scientifically about interaction between light beams resin-composites can significantly promote effective clinical placement restorations. Neglect such study result practical procedures light-curing that are inadequate or even seriously defective. Method This review addresses underlying science technology elucidate curing works, for dental resin-based composites, including—but not limited to—bulk fill types. involves questions concerning: (a) particle-wave light; (b) photons penetrate sufficiently deeply into bulk composites; (c) necessary LED units (LCUs); (d) criteria absorption by photo initiators initiate free-radical addition polymerisation. Conclusions The implications practice surveyed. These include design variables selection LED-LCUs guidelines on their use. is guide practitioners towards safe so achieve optimal patients.
