Objective: To evaluate the bacterial inhibition limit of Calcium Hydroxide powder on strains of Enterococcus faecalis ATCC® 29212™. Materials and Methods: This in vitro experimental study used 40 petri dishes with solidified BHI agar. The solution of Calcium Hydroxide [Ca(OH)2] powder of the brand Biodinámica and Maquira was prepared at the concentration of 1 g / ml. The Minimum Inhibitory Concentration (MIC) and the Minimum Bacteriostatic Concentration (MBC) were evaluated using different concentrations of Ca(OH)2 (0.02 g /ml - 1 g/ml). The CMI was evaluated using the Kirby Bauer technique and the CMB using the Colonies Formation Units (CFU) technique. Results: The antibacterial activity of Ca(OH)2 against the E. faecalis strain, presented the following means of inhibition halo were observed: Biodinámica 22.66 ± 0.38 mm; Maquira 23.58 ± 0.47 mm and 12% Chlorhexidine (positive control) 23.93 ± 0.73 mm. The MIC of the Ca(OH)2 powder of both brands was 0.063 g / ml as the lower limit, confirming the inhibition of the growth of Enterococcus faecalis ATCC ® 29212 ™ strain with the upper limit of 1 g / ml. On the other hand, CMB of the Ca(OH)2 powder shows a value of 0.031 g / ml for Biodinámica and 0.063 g / ml. for Maquira. Conclusion: The lower and upper limit of bacterial inhibition of Calcium Hydroxide, on strains of Enterococcus faecalis ATCC ® 29212™ was 0.063 g / ml and 1 g / ml, respectively.
