 The root canals were obturated with gutta-percha and a resin based sealer AH26, De Trey Dentsply, Konstanz, Germany using cold lateral compaction technique. A standardized master cone size 40.02 gutta-percha was fitted with tug back at the working length. The gutta-percha cone was lightly coated with sealer and slowly inserted into the canal. Cold lateral compaction with accessory gutta-percha cones size 15 was performed until these could not be introduced more than 5 mm into the root canal. All canals were shaped, cleaned, and obturated in a single-visit.
