N2  - This study was performed to compare the power bleaching effect of various bleaching systems on temperature rise and color changes of anterior teeth at different time periods. Eight products with hydrogen peroxide concentrations ranging from 25% to 40% were evaluated. The treatment contact time varied from 30 to 45min according to the manufacturer{u2019}s instructions.  Sixty four extracted human anterior teeth were selected. The crowns of all teeth were sectioned in the mesiodistal direction with a cutting machine under water irrigation to facilitate the access to the pulp chamber for the temperature measurements. The specimens were stained with a standardized tea solution method
