    The objective of this research was to determine, through an in vitro study, the antibacterial capacity of an epoxy resin and calcium hydroxide-based endodontic sealer against Enterococcus Faecalis. Materials and Methods: The antibacterial capacity was evaluated using the disc diffusion test. For this, 14 Petri dishes were prepared with the culture medium (Mueller Hinton Agar) and left to gel for 24 hours before inoculating Enterococcus Faecalis ATCC 29212 using the swab technique. Then, 4 cavities of 5 mm in diameter were made, where the epoxy resin-based endodontic sealer (Vioseal), calcium hydroxide-based sealer (Sealer 26), negative control (physiological serum), and positive control (2% chlorhexidine gluconate) were placed. The reading of the bacterial inhibition zones was performed using a digital caliper at 2, 24, 48, and 72 hours. Vioseal showed the greatest statistically significant antibacterial capacity when compared to Sealer 26 (p < 0.05). In conclusion, 2% chlorhexidine gluconate demonstrated the highest antibacterial capacity, followed by Vioseal and Sealer, respectively.
