Abstract
The apical sealing ability of the standard lateral condensation technique, vertical condensation technique, single gutta-percha technique and combined technique was measured and compared. Root canals of 40 single-rooted teeth were instrumented using the step back technique. Six additional teeth were used as controls. The apical leakage was measured using a stereomicroscope after submerging the root apices in a 1% methylene blue water solution. The best result was obtained with the lateral condensation technique (0.93±0.80 mm), followed by the vertical condensation technique (1.79±1.02 mm) and single gutta-percha cone (I.93±1.38 mm). The poorest result was obtained with the combined obturation technique (1.97±0.80 mm). The difference between the lateral condensation obturation technique and combined technique was statistically significant (p<0.05).
