| Summary: | Objective: The aim of this study was to evaluate comparatively the physical properties of solubility, disintegration and flow of some root canal sealers: SEALAPEX™, PULP CANAL SEALER™, TUBLISEAL™, AH PLUS™, AH 26™, TOP SEAL™, SEALER PLUS™, SEALER 26™ and ENDOFILL™. Method: Methodology used was according ISO 6786 which test the physicochemical properties using five proof specimens for each test. Results: In terms of solubility, the root canal sealers analyzed have been classified in the following decreasing order: ENDOFILL™, SEALAPEX™, PULP CANAL SEALER™, AH 26™, TUBLISEAL™, SEALER PLUS™, AH PLUS™, TOP SEAL™ and SEALER 26™, where a statistically significant difference was found at a 1% level. Between TOP SEAL™ and SEALER™ 26 root canal sealers there was no statistically significant difference. None of the sealers above have shown disintegration. Regarding flow, the root canal sealers in the study have been classified in the following decreasing order: TUBLISEAL™ root canal sealer, followed by ENDOFILL™, SEALAPEX™, PULP CANAL SEALER™, AH PLUS™, TOP SEAL™, AH 26™, SEALER 26™ and SEALER PLUS™, where a statistically significant difference was found at a 1% level. Conclusion: The solubility, only the SEALAPEX™ and ENDOFILL™ have shown a limit above determined by ISO 6786.
