    The objective of this study was to determine the antibacterial capacity of two endodontic cements based on calcium hydroxide and zinc oxide against Enterococcus Faecalis strains. In this in vitro, experimental, longitudinal, and prospective research, the sample consisted of 40 specimens divided into two experimental groups and two control groups. The agar diffusion test was used to determine the antibacterial capacity. For this, the Enterococcus Faecalis ATCC 29212 strain was inoculated onto Mueller Hinton agar plates, and four equidistant perforations were made where the materials were placed. The antibacterial capacity was evaluated by measuring the inhibition halos at 2, 24, and 48 hours. It was found that chlorhexidine gluconate produced the largest bacterial growth inhibition halos, which were statistically significant (p<0.05). When comparing the endodontic cements, it was found that the calcium hydroxide-based endodontic cement produced the largest bacterial growth inhibition halos, which were statistically significant compared to the zinc oxide-based endodontic cement (p<0.05). Conclusion: The calcium hydroxide-based endodontic cement demonstrated better antibacterial capacity against Enterococcus Faecalis.
