  • Abstract - 2017 - International Endodontic Journal -

    A total of 206 survey invitations were successfully delivered. Positive response rate was 93.7% for DS (n = 15) and 47% for ES (n = 97). Among DS, 86.7% used sodium hypochlorite (NaOCl) between 0.5% and 2.5%, either ‘ready to use’ bottles (66.7%) or prepared extemporaneously (33.3%). Lateral opening needles were the most commonly available (60%).
