摘要：
A tooth-whitening process includes providing an array of LEDs (20) disposed in a first plane and forming an inner arc (30) having an inner focal point (31) and an outer arc (40) having an outer focal point (41) different from the inner focal point； applying a whitening composition to at least the anterior surfaces of at least six mandibular or maxillary anterior teeth and maintaining the whitening composition on the at least six teeth for a first time period； after the first time period, directing a light radiation comprising blue visible light or near-visible UV light of at least a threshold intensity from the least a first array of LEDs for a second time period to the anterior surfaces of the at least six teeth, the first time period having a duration greater than 50% of a total duration of the first time period and the second time period； and removing the whitening composition from the at least six teeth.
