— The purpose of the present study was to evaluate the apical seal of root canals filled with a cold lateral condensation, a hybrid gutta‐percha condensation technique and with Soft‐Core obturators. Three groups of 35 maxillary anterior teeth and four control anterior teeth were treated with a crown‐down/step‐back technique. All roots were submerged in India ink for 1 week. The roots were cleared and the degree of linear dye penetration was measured. The mean apical leakage for the Soft‐Core technique was at least twice as extensive as for the two other gutta‐percha obturation techniques. No statistically significant differences were found between the two other condensation techniques.
