One third of the crown of root canal was drilled with G drill, then 1 / 3 of root canal was prepared with S1 file, 1 / 3 of root canal was prepared with S2 file, 1 / 3 of root tip was prepared with F1 file, 3% hydrogen peroxide solution and 2.5% sodium hypochlorite solution were used alternately to wash and dry.
