Objective: The objective of this study was to evaluate the effect of two irrigants, Nano silver, and QMIX 2IN1 on the adaptability and seal ability of gutta-core. Materials and methods: A total number of 120 extracted human straight single-rooted premolars were collected. Root canals were cleaned and shaped using the crown-down technique to a master apical file size of 40. Samples were divided into three groups (n=40) according to the irrigating solution: G1, 5.25% naocl; G2, Nano silver; G3, QMIX 2INI1. Each group was subdivided into two subgroups according to the obturation materials. Subgroup A, Gutta-Core, and subgroup B, Thermafil. Stereomicroscope and fluid filtration methods were used to evaluate the adaptability and seal ability of Gutta-Core and Thermafil. Data were statistically analyzed using one-way ANOVA. Results: Regarding the obturating materials, Gutta-Core showed statistically significantly higher adaptability mean values than Thermafil. The apical level of the root canal showed the highest leakage than the middle and coronal levels. Conclusion: QMIX 2IN1 and Nano silver irrigants enhance the adaptability of obturating material. Gutta-core is a promising obturating material. Adaptability is a problem with the apical third of the root canal.
