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 single-peak LED LCUs. Methods Samples of Vit-l-escence (Ultradent) and Herculite XRV Ultra (Kerr) and fissure sealants Delton Clear and Delton Opaque (Dentsply) were prepared (n = 3 per group) and cured with either one of two dual-peak LCUs (bluephase® G2; Ivoclar Vivadent or Valo; Ultradent) or a single-peak (bluephase®; Ivoclar Vivadent). High-performance liquid chromatography and nuclear magnetic resonance spectroscopy were used to confirm the presence or absence of initiators other than camphorquinone. The DC was determined using micro-Raman spectroscopy. Data were analysed using general linear model anova; α = 0.05. Results With Herculite XRV Ultra, the single-peak LCU gave higher DC values than either of the two dual-peak LCUs (P
