| Abstract | ||
| ABSTRACTBackground: This study investigated the influence of different new curing modes on the depth of cure of different light- activated composites to determine to the thickness of a composite layer that could be adequately cured clinically with these new curing modes.Materials and methods: This study investigated the depth of cure after exposure to different curing modes. Parameters included six curing modes: Control (C), Pulse Delay I (PDI), Pulse Delay II (PDII), Soft-start (SS), Pulse Cure I (PCI), and Pulse Cure II (PCII) plus three experimental curing modes of higher energy density: Prolonged low-intensity pulse cure mode (PLPC), Prolonged moderate-intensity pulse cure mode (PMPC) and Rapid high-intensity continues cure mode (RHCC) for each of the four different light-activated composite materials (Tetric Ceram, Heliomolar, Herculite XRV and Degufill Mineral).Results: Statistical analysis of the data by using the one-way analysis of variance revealed that, there is statistically very highly significant difference for all the depth of cures between the curing modes and composite types.Conclusion: This study indicated that, although, both curing mode and composite type significantly affect depth of cure but the effect of composite composition on the depth of cure is much more than that of curing mode.Key words: Composite, light curing modes, depth of cure.
