Actividad antimicrobiana in vitro del chitosan/propóleo en gel sobre el enterococcus faecalis

Abstract

Purpose: Comparing the antibacterial efficiency of chitosan / propolis gel, calcium hydroxide (Calcifar-P), chlorhexidine gel 2%, 30% propolis extract and chitosan gel on Enterococcus faecalis.

Materials and methods: A cross - sectional in vitro study was carried out, using agar diffusion with Kirby - Bauer method. The samples were 14 replications per group and were calculated using Fisterra program. The inhibitory halos were measured in millimeters after 24 hours of incubation, at 37 ° C; the results obtained were processed by the statistical tests of Shapiro-Wilk, Kruskal-Wallis and Kolmogorov-Smirnov.

Results: The average of the chitosan / propolis gel inhibitory halo was 22.36 mm, the one with Calcifar-P was 13.93 mm, in the case of chlorhexidine gel 2% 15.86 mm, the chitosan gel had an average inhibitory halo of 17.71 mm, the 30% propolis extract had the lowest average with a value of 11.36 mm. None of the above values exceeded the positive control whose average was 34.86 mm.

Conclusion: This study concluded that chitosan / propolis gel has better antimicrobial efficiency compared with calcium hydroxide (Calcifar-P), 2% gel chlorhexidine, 30% propolis extract and chitosan gel.
