Objective: Compare the in vitro surface microhardness of a Bulk Fill resin subjected to different techniques to eliminate the oxygen-inhibited layer. Materials and Methods: This experimental study included a sample of 80 Tetric® N-Ceram Bulk Fill resin blocks, each measuring 6mm in diameter and 4mm in depth, distributed into four groups according to the technique used to eliminate the oxygen-inhibited layer: G1: control, G2: celluloid strip, G3: polishing, and G4: glycerin. Surface microhardness was evaluated using the Vickers scale, and the results were analyzed using ANOVA, followed by Tukey's Post Hoc test, with a significance level of 0.05. Results: The in vitro surface microhardness of the bulk-fill resin subjected to the celluloid strip technique was 44.30 ± 2.36 HV, followed by polishing at 43.18 ± 2.85 HV, glycerin at 34.96 ± 2.12 HV, and the control group at 33.37 ± 1.54 HV. Significant differences were found between the techniques, except between the celluloid strip and polishing (p=0.406), and between glycerin and the control group (p=0.132). Conclusions: The in vitro surface microhardness of a bulk-fill resin subjected to the polishing and celluloid strip techniques for eliminating the oxygen-inhibited layer was higher than that of the glycerin technique
