    The aim of this research was to compare the flexural strength of three brands of fiberglass posts: Fiber Post (Maquira), Refor Post (Ángelus), and Micro Medica (Simplex). An in vitro, comparative, prospective, and cross-sectional study was conducted with 30 fiberglass posts from three brands: Fiber Post (Maquira), Refor Post (Ángelus), and Micro Medica (Simplex), divided into three subgroups, each consisting of 10 fiberglass posts. Flexural strength was determined using a universal testing machine. Numerical values were collected using a data collection form, and the data was analyzed using the SPSS version 22.0 statistical software. The results showed that the flexural strength of the Refor Post fiberglass post had an average of 887.49 MPa, followed by Fiber Post and Micro Medica with averages of 798.91 MPa and 607.75 MPa, respectively. In conclusion, the Refor Post fiberglass post showed superior resistance compared to the Fiber Post and Micro Medica brands.
