Microstructure and wettability of root canal dentine and root canal filling materials after different chemical irrigation

- Different irrigation solutions and disinfectants were used for treatment of root canal dentine and gutta-percha points.
- Materials surface characteristics were assessed using quantitative backscattered electron imaging, reference point indentation, and contact angle analyzer.
- The most significant differences in mineralization, indentation, and adhesive outcomes were observed after ethylenediaminetetraacetic acid treatment.
- Irrigation solutions confer to superior sealing ability of endodontic filling materials.
- Micromechanical characteristics of dentine after irrigation are considerable reduced.
