Multi-Wavelength Curing Lights Replace Single-Peak LED Units
First-generation LED curing lights emitted a narrow blue wavelength band tuned to camphorquinone photoinitiators, but newer bulk-fill and fast-set composites increasingly rely on alternative photoinitiators requiring violet and near-UV wavelengths those older lights cannot produce. Manufacturers including Ultradent and Ivoclar Vivadent have shifted new product lines almost entirely to multi-wavelength or broad-spectrum output to guarantee compatibility across the full range of resins a practice might use. Clinicians who mismatch light and resin risk under-cured restorations that fail prematurely, a quality problem malpractice insurers have begun flagging explicitly in continuing education materials distributed to dental practices.
