    Compressive strength of three bioceramic cements: mta, biodentine and mta repair hp, - in vitro. lima 2020

    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.

    Evaluation of apical microleakage using two filling cements: Bioceramic Sealer Flo (Alavon Biomed) vs MTA Fillapex Angelus in single root premolars, in vitro study in 2021
    (Universidad Privada Norbert Wiener, 2022-01-06) Rivera Isasi, Josue Sebastian; Huamani Caquiamarca, Yuliana Esther
    Objective: To evaluate apical microleakage using two obturation cements: bioceramic Neo Sealer Flo (Alavon Biomed) vs. MTA Fillapex® Angelus in single-rooted premolars, an in vitro study in 2021. Materials and Methods: Hypothetical-deductive method with a quantitative approach, experimental in vitro type, and an observational, analytical, cross-sectional experimental design. The sample consisted of 40 dental pieces. Results: For the bioceramic Neo Sealer Flo (Alavon Biomed), 77.5% (31 pieces) showed Grade 1, indicating greater effectiveness and reduced apical microleakage. Additionally, 20% (8 pieces) were Grade 2, and 2.5% (1 piece) was Grade 3. For the MTA-based sealer cement MTA Fillapex® Angelus, 77.5% (31 pieces) showed Grade 2, reflecting moderate effectiveness with suboptimal apical microleakage, and 22.5% (9 pieces) were Grade 3. Conclusion: Based on the results, bioceramic cements offer superior advantages and properties. The bioceramic Neo Sealer Flo is an ideal alternative for three-dimensional sealing of root canals due to its described properties, compared to MTA-based sealer cements like MTA Fillapex® Angelus.
