METHODS： Dentists in different hospitals were asked to fill in the questionnaire, which included the methods and factors of the first-choice treatment of endodontic diseases, instruments and materials used in RCT.

The reply rate was 91.1%. RCT was performed as the first-choice of endodontic treatment in 93.5% of total 410 dentists. And 90.2 % of them used hand instruments to prepare .root canals. Push-pull or stepback technique was widely used in anterior or posterior root canal preparation. Hydrogen peroxide was adopted to irrigate root canal by the majority of respondents （88.3%）. Nearly half of the respondents used camphorate phenol as intracanal medicine. 77.6% of them adopted cold lateral condensation technique and 32.7% of them used gutta-percha mixing with iodoform for canal obturation. 74.6% of them applied one-visit endodontic treatment sometime and prescribed antibiotics or hormone to the patients after RCT.
