The aim of this study was to evaluate in vitro the apical sealing ability of cold lateral and system B root filling techniques using dye penetration. Eighty‐six extracted single‐rooted human teeth were prepared and randomly divided into two experimental groups to be obturated by cold lateral condensation ( n = 33) and system B ( n = 33). The remaining 20 teeth served as positive and negative controls. The roots were embedded for 72 h in methylene blue dye solution and sectioned transversely for dye penetration evaluation using stereomicroscope. The results of this study showed that cold lateral condensation leaked significantly more ( P < 0.001) than system B technique.
