To evaluate the bond strength and adhesive interface quality between root dentin and pre-mixed bioceramic sealers: AH Plus Bioceramic, Bio-C Sealer, and NeoSEALER Flo. Thirty-six single-rooted teeth were endodontically treated and divided into three groups (n = 12) based on the sealer used: GI-AH Plus Bioceramic
GII-Bio-C Sealer
GIII-NeoSEALER Flo. Fluorescein dye was added to two samples of each group. After three times the sealer's setting time, specimens were sectioned. The first and second slices underwent push-out testing with failure pattern analysis (n = 10). The third slice was used for confocal laser scanning microscopy (CLSM) (n = 10). Samples with dye were analyzed using confocal laser scanning fluorescence microscopy (CLSM). Data were analyzed using ANOVA, χ
