| Deskribapena: | This in vitro study investigated the push-out bond strength and adaptation of three root canal sealers AH Plus Jet (epoxy resin-based), MTA Fillapex, and EndoSeal Mineral Trioxide Aggregate (MTA) both with and without gutta-percha obturation, utilizing 90 straight, single-rooted teeth randomly assigned to groups and subgroups. Push-out bond strength was measured using an Instron universal testing machine, while adaptation was assessed via scanning electron microscopy, with statistical analysis performed using one-way ANOVA and Tukey's post-hoc test (p<0.05). EndoSeal MTA demonstrated the highest statistically significant push-out bond strength (p<0.001) in both conditions, though no significant difference existed between MTA Fillapex and AH Plus Jet without gutta-percha, where AH Plus Jet still showed higher bond strength at root levels than MTA Fillapex (p<0.001). While adaptation showed no significant differences among sealers with gutta-percha, AH Plus Jet achieved the lowest significant gap percentage in its absence. Ultimately, EndoSeal MTA exhibited the highest push-out bond strength overall, making its superior adhesion a promising choice for root canal obturation. |
