Abstract: The aim of this study was to evaluate the efficacy on the cleansing of root walls from several hydraulic endodontic sealers , of smear layer, of the debris, and gutta-percha after the preparation of the restorative space. Methods: Xxx single rooted have been collected. All the samples were prepared by the same operator (DIKP), using Nickel-titanium rotating instruments (MTwo) through the Simultaneous Shaping Technique. The Continuous-wave of condensation technique of obturation was used in combination with the tested hydraulic endodontic sealers. To all specimens, the restorative space has been made, leaving 5 mm of apical gutta-percha and performed postoperative periapical X-Rays. The samples were randomly divided into 4 groups: Group A: traditional endodonti sealer; Group B): Experimental GC hydraulic sealer; Group C: OneFill hydraulic sealer; Group 4: Ceraseal hydraulic sealer. Accortdingly with the used cleansing procedure, the 4 Groups were subdivided in 3 SubGroups: A: no cleansing after preparation of root canal space; B: Cleansing with EDTA 17%; C: Cleansing with ETDA 17% ultrasonic activated. All dental sample groups were cut longitudinally with a low-speed saw (Isomet); the samples were observed using a scanning electron microscope (Jeol, Jsm-6060LV) to evaluate: 1. Amount of debris/ smear layer, 2. Amount of obstruction of dentinal tubules found in the groups, 3. Evaluation of the presence of hydraulic endodontic sealer. Statistical analysis was performed by Mann-Whitney non-parametric comparison test. Results: The SEM observations showed that to clean the root canal wall from hydraulic sealer EDTA 17% activated with ultrasonic device are needed. The traditional sealer was statistically significant better cleaned from root canal walls than hydraulic sealers. Conclusions: The hydraulic endodontic sealers are cleaned with more difficulty than traditional endodontic sealer.  

Clinical significance: The hydraulic endodontic sealers can be an obstacle to adhesive reconstruction of endodontically treated teeth.
