Aim: To analyze the physical-chemical properties, flow, setting time, solubility and dimensional change of endodontic cements, based on zinc oxide and eugenol: Endomethasone N, Endo fill, and Grosmann, according to specification number 57 of the American Dental Association.
Methods: The tests were conducted under environmental conditions of 23° ± 2°C and 50 ± 5% relative air humidity, maintained for 48 h prior to the procedures, repeating five times and obtaining an arithmetic mean.
Results: The cements based on zinc oxide and eugenol analyzed in this study showed high hardening times. For the flow test, Endo fill and Grossman were above the established parameters. Regarding solubility, Endomethasone N was within the standard, while the other cements exceeded this standard.
Conclusion: All analyzed cements obtained values that proved to be different from those recommended for dimensional changes. None of the cements were completely compliant with the regulations.
