Resumen
TORRES, Sofía Cristina; GUTIERREZ DE FERRO, Marta Inés; TRACANNA, María Inés y GUTIERREZ, Susana. Estudio de la actividad antimicrobiana de Xenophyllum poposum sobre microorganismos de la cavidad bucal por el método de difusión radial. Acta bioquím. clín. latinoam. [online]. 2022, vol.56, n.1, pp.37-42. ISSN 0325-2957.
In this study, the in vitro antimicrobial activity of Xenophyllum poposum extracts on oral microorganisms such as Streptococcus mutans, Streptococcus sobrinus, Lactobacillus casei, Actinomyces naeslundii, Actinomyces odontolyticus, Candida albicans, Veillonella sp. was evaluated. The radial diffusion method in agar was used and 0.12% ethanol and chlorhexidine (Plac out NF®) were used as negative and positive inhibition controls, respectively. The extracts with the highest antimicrobial activity were the ethanolic and chloroform extracts. The difference between the two was not statistically significant (p≥0.05). No significant difference was observed with respect to chlorhexidine, except on Veillonella sp., since the ethanolic extract presented significantly lower inhibition halos on this microorganism. This is important as Veillonella is considered an indicator of health in relation to dental caries. Based on this, the ethanolic extract of Xenophyllum poposum could be used as chemical control of dental biofilm.
