of the dental bleaching efficacy in deciduous teeth with diode laser and led irradiation : An in vitro study

The purpose of this study was to compare the efficacy of bleaching in deciduous teeth with Diode Laser and LED Irradiation. Forty extracted caries free central incisors were used for the study (there Ciel*a*b* values were recorded). All the forty teeth were first discolored in the solution made of coco cola and tea (Ciel*a*b* values were recorded) and were then divided into 2 groups A (Laser) & B (LED). Discolored Samples in Group A were treated with the bleaching agent assisted by Laser and then there Ciel*a*b* values were recorded. Discolored Samples in Group A were treated with the bleaching agent assisted by LED and then there Ciel*a*b* values were recorded.
