title: Effect of glutaraldehyde-based cold sterilization solutions on light transmission of single-use, plastic light-curing tips.
abstract: Previous research has demonstrated that autoclaving of conventional curing tips results in the build-up of an opaque scale on the curing tips ends, greatly reducing light intensity output. Cold sterilization of conventional light-curing tips in most glutaraldehyde-based solutions did not damage the tip or decrease light-transmission quality. However, the specific brand of cold sterilant was found to be of importance, as one specific product was shown to decrease light-tip intensity values irreversibly, even after subsequent tip polishing. A decrease in light intensity output from the curing source significantly affects polymer cure and the biological properties of the restorative material.
