Abstract

Summary. Thirty‐five single rooted teeth were biomechanically instrumented with salaine, following' which they were subjected to different methods of irrigation. Four groups of teeth were irrigatied using and Endomate unit with NaOCl in combination with H2O2, or EDTA, or glutaraldehde or saline. Two groups were irrigated with 5 per cent NaOCl in combination with ultrasound; one of them was further irrigated with 3 per cent H2O2 using the Endomate system. The control group was irrigated with NaOCl and H2O2 using the conventional technique. The prepared root canals were examined for the presence of smear layer under SEM. All groups irrigated with the ultrasonic technique and the group irrigated with the endomate system using EDTA solution showed significantly cleaner surfaces; the smear layer was also greatly reduced.
