As can be seen in Table 2, all sealers met this condition. In the present study, it could be observed that the sealer obtained using 120-180 day old eugenol had greater flow, with a possible decrease of liquid viscosity due to oxidation. Analysis of setting time results showed that after 30 days eugenol was altered causing a decrease in sealer setting time. Based on the research of Fragola et al. Thus, it can be observed that Grossman root canal sealers obtained from aged eugenol are prone to a faster setting time.
Traction is a vectorial force constituted by intensity, direction and orientation.
Traction tension is a scalar value constituted only by intensity. Considering that the adhesion of a sealer is directly proportional to the traction tension, it can be said that adhesion will be as great as the force necessary to displace the sample containing the tested sealer. Adhesion of a root canal sealer means its capacity to attach to the dentinal walls of the root canal and provide bonding between it and gutta-percha points. The American Dental Association did not standardize any method for studying the adhesion of root canal sealers due to a lack of consensus among researchers. The authors observed that the adhesion test gauged by the Universal testing machine promotes a better uniformity and greater reproducibility, providing more accurate results.
