    The aim of this research is to evaluate the surface microhardness of low-viscosity flowable composite resins, 3M Filtek Flow™, Tetric N-Flow, and Opallis Flow for use as dental sealants. A comparative, in vitro, descriptive, prospective, and cross-sectional study was conducted, consisting of 60 low-viscosity flowable resin cylinders, divided into 20 cylinders for each group. The samples were measured after 24 hours. Microhardness was evaluated using a Vickers microhardness tester, applying a 50-gram indentation on each sample in each resin cylinder. Data were collected on a data collection form and analyzed with SPSS statistical software, version 22.0. The results of surface microhardness showed that the Opallis Flow resin had a value of 52.23 Kg/mm², followed by Tetric N-Flow with a value of 40.72 Kg/mm², and 3M Filtek Flow™ with 40.17 Kg/mm². In conclusion, the Opallis Flow resin has the highest surface microhardness compared to Tetric N-Flow and 3M Filtek Flow™
