Visible-light-activated Resin Composites
The relationships between the transmission coefficient and the cure depth were evaluated on eight commercially available light-activated resin composites. The determination of transmission coefficient was carried out by the use of a radiometer for various shades of the resin composites. The transmission coefficient, ranging from 0.042 to 0.263, wasdependent upon the shade of the resin. There wa...
متن کاملVisible Light Curable Restorative Composites for Dental Applications Based on Epoxy Monomer
A cationic photo-curable cycloaliphatic epoxy resin has been investigated as reactive monomer in blue light crosslinking process. We have demonstrated that camphorquinone is able to abstract labile hydrogen from the epoxy monomer, giving rise to the formation of carbon-centered radicals that are oxidized by the onium salt; a complete epoxy group conversion was reached after 50 s of irradiation....

متن کاملCuring Efficacy of Light Emitting Diodes of Dental Curing Units
BACKGROUND AND AIMS The aim of the present study was to compare the efficacy of quartz tungsten halogen (QTH) and light emitting diode (LED) curing lights on polymerization of resin composite. MATERIALS AND METHODS A hybrid resin composite was used to prepare samples which were cured using two QTH and ten LED light curing sources. Twelve groups, each containing ten samples, were prepared usin...
متن کاملDepth of Cure of Dental Composites Submitted to Different Light-curing Modes
OBJECTIVE This study evaluated the depth of cure of five dental composites submitted to different light-curing modes. MATERIAL AND METHODS Canal-shaped cavities with 5mm of length were prepared on the buccal surfaces of extracted third molars, and restored using P-60, A-110, Admira, Z-250 and Supreme resin composites. Materials were light-cured from the top, according to three modes (Group 1-...
