TL;DR: Tooth whitening products may be in contact with intraoral structures for several hours or they may be used daily to whiten the teeth, Consequently, these products should have a relatively neutral pH to minimize potential damage.

TL;DR: Understanding of the basic events occurring in any dental polymerization mechanism, regardless of the mode of activating the process, will allow clinicians to both better appreciate the tremendous improvements that have been made over the years, and provide valuable information on differences among strategies manufacturers use to optimize product performance.

TL;DR: Assessments and research publications should include the following information about the curing light: radiant power output throughout the exposure cycle and the spectral radiant power as a function of wavelength, and analysis of the light beam profile and spectral emission across the light beams.

TL;DR: The design of the light guide of a light curing unit affects light dispersion, power density, and ultimately the dentist's ability to properly cure composite, since significant differences exist between light guide designs.

TL;DR: The ability to reduce exposure times with high-power LED or QTH lights may improve clinical time management and reduce the microhardness of resin composites cured with a "second-generation" light-emitting diode (LED) curing light and a quartz-tungsten-halogen curing light.
