Abstract
Aims: To compare flow, film thickness, and 24-h solubility assessed by net mass change of Well-Root ST, Bioserra, and AH Plus Jet. Methods: Ten specimens were tested per material. Flow was measured using 0.05 ml of sealer under 120 g, including upper glass plate. Film thickness was calculated from the change in glass-plate thickness under 150 N, and solubility from mass change after 24-h water immersion. The Shapiro-Wilk and Levene tests evaluated normality and variance homogeneity. Flow and film thickness were analyzed using one-way ANOVA and Tukey’s test, whereas solubility was analyzed using the Kruskal-Wallis test with Bonferroni correction (p<0.05). Results: Flow differed significantly among the sealers (F=13.421, p<0.001, η²=0.499). Bioserra showed the lowest flow (22.96160±2.32206 mm), followed by Well-Root ST (26.73610±3.56334 mm) and AH Plus Jet automix (30.74825±3.97539 mm), with significant differences between all pairs. Film thickness also differed significantly (F=7.203, p=0.003, η²=0.348). Bioserra (96.2±27.89 µm) had a greater film thickness than AH Plus Jet (46.0±23.65 µm; p=0.002), whereas Well-Root ST (67.6±36.11 µm) did not differ from either material. No significant difference in 24-h solubility was detected (H=4.355, p=0.113). Conclusion: Within the limitations of this in vitro study, the sealers differed in flow and film thickness but not in 24-h solubility. All met the ISO flow requirement, whereas the mean film thicknesses of Well-Root ST and Bioserra exceeded 50 µm.
