    The objective of this research was to determine the antibacterial effect of Fortrimax paste in comparison with Trimix-MP paste on the Enterococcus Faecalis ATCC® 29212 strain. This study was developed in vitro at the microbiology laboratory of Universidad Privada Norbert Wiener, using the modified well diffusion method. The study population consisted of 160 Petri dishes containing Mueller Hinton agar, inoculated with Enterococcus faecalis, and distributed into 40 Petri dishes for each sample. A 6mm well was perforated in each plate, where the antibiotic paste was deposited, and incubated at 37ºC. The measurements of inhibition halos were taken at 24, 48 hours, and 7 days. The data were processed using the Mann-Whitney statistical test for comparisons. The Fortrimax paste showed a greater inhibitory effect, with an average of 36.5mm at 24 hours, 39.06mm at 48 hours, and 39.79mm at 7 days, showing an increasing trend in inhibition. The Trimix paste showed 30.38mm at 24 hours, 29.70mm at 48 hours, and 29.41mm at 7 days of inhibition. Finally, the positive control paste (Calcium Hydroxide) showed 13.15mm at 24 hours, 13.08mm at 48 hours, and 12.90mm at 7 days, demonstrating a lower inhibitory effect. The study concluded that Fortrimax paste had a better antibacterial effect and higher inhibition compared to Trimix paste and Calcium Hydroxide paste on the Enterococcus faecalis strain.
