    Objective: To determine the compressive strength of three bioceramic cements: Mineral Trioxide Aggregate (MTA), MTA Repair HP, and Biodentine in vitro. Methodology: The total sample consisted of 60 blocks, divided into 20 for each bioceramic cement group. The study was experimental, longitudinal, and comparative, where the compressive strength of three bioceramic cements—Mineral Trioxide Aggregate (MTA), MTA Repair HP, and Biodentine—was measured in vitro at 24 and 48 hours after preparation. Statistical analysis was performed using the ANOVA and Shapiro statistical tests. Results: For all three cements, the compressive strength was higher at 48 hours than at 24 hours: MTA 3.69 MPa/2.51 MPa; MTA Repair HP 2.96 MPa/1.47 MPa; and Biodentine 69.97 MPa/51.28 MPa, with a significant difference (p<0.001). A time-dependent difference was observed between MTA and MTA Repair HP (p<0.001). Conclusion: Biodentine demonstrated higher compressive strength compared to MTA and MTA Repair HP, making it a better alternative among calcium silicate-based bioceramic materials.
