Introduction: Apical sealing is the key to success in an endodontic treatment, this study seeks to compare the apical sealing capacity between the AH Plus sealant and the BioRoot sealant with and without the use of gutta-percha, 20 acrylic teeth were used that went through a complete endodontic treatment, following the appropriate guidelines and procedures, AH plus with gutta-percha, HA plus without gutta-percha, BioRoot with gutta-percha and BioRoot without gutta-percha were divided into 4 groups, after completing the filling, apical filtration was evaluated by immersing the teeth in methylene blue and taking data on its penetration. Objectives: To compare the apical sealing capacity between bioceramic sealants and HA plus with and without gutta-percha in endodontic treatments by means of an in vitro study. Methodology: The study is in vitro and seeks to compare the apical sealing capacity between the AH Plus sealant (based on epoxy resin) and the BioRoot RCS sealant (bioceramic), with and without the use of gutta-percha. 20 acrylic teeth were used and received complete endodontic treatment. These were divided into four experimental groups: AH Plus with gutta-percha, AH Plus without gutta-percha, BioRoot with gutta-percha, and BioRoot without gutta-percha. The evaluation of apical filtration was performed by immersing the teeth in methylene blue and measuring its penetration. Results: the text does not present the numerical or descriptive data of the results. The results are expected to compare microfiltration between the four groups to determine the most effective combination for optimal apical sealing and to analyze the influence of gutta-percha on the efficacy of both sealants. The aim is to determine whether the simplification of the gutta-percha technique, especially with bioceramic sealants, offers a comparable or superior seal. Conclusions: The conclusions of the study, once conducted, will focus on identifying the combination (sealant and use/absence of gutta-percha) that offers the best performance in the prevention of apical leaks. It will be concluded about the real need for gutta-percha in root canal filling when using modern sealants such as bioceramics (BioRoot RCS) compared to a traditional sealant such as AH Plus.
