520			_aThis study was performed to evaluate the effectiveness of Laser bleaching technique compared to Chemical and light tooth bleaching by using digital colour detection. The study was conducted on sixty freshly extracted human upper central Incisors that were collected from patients complaining from high grade teeth mobility due to advanced periodontal diseases. The selected teeth were sound and free from cracks, decay, or any other defects that might have affected enamel .All data were collected, tabulated, and statistically analyzed. Descriptive statistics as recorded values, absolute values, average and standard deviation were calculated for the three bleaching groups.Teeth were extracted, collected, and stored in saline solution at 37{u00B0}c three months prior testing
