Forty single-rooted human mandibular premolar were instrumented with hand ProTaper instruments and obturated with gutta-percha and Zinc oxide eugenol sealer. Then all teeth were divided to two group the first group received immediate post space preparation half teeth with hot plugger and other half with peeso reamer, the roots were coated with nail varnish and were immersed in methylene blue 2% for 72 hours in an incubator. After one week the other group received delayed post space preparation same as the first group and coated with nail varnish and were immersed in methylene blue 2% for 72 hours in an incubator. All roots splitted longitudinally and the apical leakage measured and compared for each group. The minimal leakage value and the lowest mean of leakage were observed in subgroup one, while the maximum leakage value and the highest mean of leakage was obvious in subgroup four. A significant difference was found in the group of roots that received delayed post space preparation using peeso reamers, which showed more apical leakage than other subgroups.
