El objetivo del presente estudio fue determinar el efecto inhibidor de las concentraciones mínimas del aceite esencial de Minthostachys mollis (muña) y Origanum vulgare (orégano) en comparación con sustancias antimicrobianas usadas en la terapia pulpar frente a cepas de Enterococcus faecalis. Para tal efecto se reactivaron los E. faecalis (ATCC 29212) que fueron utilizados en las dos etapas del estudio: 1.- Determinación de la concentración mínima inhibitoria (CMI) de ambos aceites esenciales. 2.- Determinación del efecto inhibidor de estos aceites esenciales en comparación a sustancias antimicrobianas usadas en la terapia pulpar. En la primera etapa del estudio se encontró que la CMI del aceite esencial de muña fue 10% y aceite esencial de orégano fue 30%. En la segunda etapa, los E. faecalis fueron sembrados en 56 placas petri que contenían el medio de cultivo Mueller Hint...

Objective: To assess the antibacterial activity of Psidium guajava fractions and their effects on adhesion of a multispecies biofilm consisting of Streptococcus gordonii, Fusobacterium nucleatum, and Porphyromonas gingivalis in vitro. Material and Methods: Guava leaves were obtained from the mountains of northern Peru, where they grow wild and free of pesticides. The antimicrobial activity of 25 mg/mL petroleum ether, 25 mg/mL dichloromethane and 25 mg/mL methanol fractions of P. guajava was evaluated by measuring inhibition halos, as well as the effect on the adhesion of multispecies biofilms at 4, 7 and 10 days of growth by measuring the optical density. In addition, antimicrobial susceptibility was compared using the Kruskal-Wallis test and its multiple comparison tests, and differences in mean biofilm adhesion between each fraction were assessed by repeated measures analysis and the ...
