Dental curing lights deliver visible light to initiate photopolymerization in compatible light-cured dental materials, including resin-based composites, sealants, and resin cements. The emitted wavelength must correspond with the material’s photoinitiator system, while irradiance, exposure time, tip distance, and beam position can affect the energy delivered. LED units may use single or multiple wavelength ranges depending on design. This category includes cordless and wired curing lights, light guides, radiometers, protective eyewear, and related accessories. Output specifications, curing modes, tip dimensions, battery systems, and included components vary by model.
