The aim of this study was to evaluate some of the physicochemical properties of a new root canal sealer.
The sealers tested were Sealer Plus compared with AH Plus. For the radiopacity, flow, solubility, and fabrication of test specimens relative to setting times, the American National Standards Institute/American Dental Association No. 57 (2000) and International Organization for Standardization 6876 (2012) specifications were followed. To measure the initial and final setting times, the ASTM C266/2008 standard was used. pH was evaluated in the time intervals of 3, 24, 72, and 168 hours. Statistical tests were applied to the results obtained at a level of significance of 5%.
The results demonstrated that the Sealer Plus sealer showed a lower radiopacity value than AH Plus sealer (P < .05); however, this was higher than the minimum value recommended by the specifications (ie, 3 mm Al). Relative to flow, the value for Sealer Plus was 19.19 mm and for AH Plus, 19.81 mm (P > .05). Sealer Plus presented initial and final setting times of 138 minutes and 210 minutes, respectively, whereas the values for AH Plus were 437 minutes and 849 minutes, respectively (P < .05). Relative to solubility, Sealer Plus presented 0.21% and AH Plus, 0.27% (P > .05). None of the sealers showed a significant increase in pH (P > .05).
Sealer Plus sealer presented physicochemical properties in accordance with American National Standards Institute/American Dental Association (2000) No. 57 and International Organization for Standardization 6876 (2012) specifications.
•New root canal sealer were introduced on the market, such as Sealer Plus sealer.•There are no studies in the specific literature about the physicochemical properties of the cited sealer.•Sealer Plus presented physicochemical properties in accordance with the specifications No. 57 of ANSI/ADA and ISO 6876.
