Eficacia antibacteriana del hidróxido de calcio como medicación intraconducto frente al enterococcus faecalis estudio in-vitro en la Universidad Católica de Cuenca – 2022.

Abstract

Root canals harbor a variety of microorganisms that cause endodontic failures, including Enterococcus faecalis, which is responsible for periapical infections due to its ability to resist high pH and form biofilms. One of the most commonly used intracanal medications is calcium hydroxide due to its bactericidal capacity and osteogenic activity, which is why it is considered the first option in endodontic therapy. Objective: To evaluate the antibacterial activity of calcium hydroxide on E. faecalis in vitro. Materials and Methods: An experimental in vitro study was performed in which E. faecalis strain ATCC 29212 was seeded in 9 mono petri boxes with Müller Hinton blood agar using the Kirby-Bauer technique. Results: The efficacy of Ca(OH)2 against E. faecalis, Ultracal resulted in an inhibitory halo of 7-8 mm, while chemically pure calcium hydroxide gave an inhibitory halo of 7-9 mm. Conclusion: Both Ultracal and chemically pure calcium hydroxide showed no significant difference in their efficacy as a medication against E. faecalis due to its antibiotic resistance.
