background. there is a lack of data on polymerization of resin-based materials (rbms) used in paediatric dentistry, using dual-peak light-emitting diode (led) light-curing units (lcus). objective. to evaluate the degree of conversion (dc) of rbms cured with dual-peak or singlepeak led lcus.
the most common method of polymerization of dental resin-based materials (rbms) such as resin-based composites (rbcs), adhesives and fissure sealants is by light curing, and to date, the camphorquinone (cq)–tertiary amine initiating system is the most commonly used photoinitiator.
