1. A method for curing a dental composition suitable for repairing a dental cavity or a dental surface comprising:

  • applying the dental composition to the cavity or surface; and

    , exposing the composition to radiation from a light emitting diode having output wavelengths selected to photo-activate a hardening chemical reaction within the composition, wherein the light emitting diode is operated at a power output in the range of about 25 mW/cm2 to about 38 mW/cm2, wherein the dental composition comprises a photo-curable composition, the light emitting diode is positioned a distance of about 7 mm±

    2 mm from the dental composition, and wherein a depth of cure of about 3 mm is achieved.
