RESUMEN

Introducción:

Las plantas medicinales han demostrado poseer propiedades antibacterianas para el control de la periodontitis.

Objetivo:

Determinar la actividad antibacteriana frente a Porphyromonas gingivalis ATCC 33277 de un gel experimental compuesto por aceite esencial de Eucalyptus globulus Labill.

Métodos:

Se realizó un estudio experimental in vitro. Se empleó el programa EPi InfoTM para el cálculo de las repeticiones. El aceite esencial se obtuvo por el método de arrastre de vapor; se identificó su composición química por cromatografía de gases acoplada a espectrometría de masas. Se evaluó la concentración mínima inhibitoria (CMI) y concentración mínima bactericida (CMB). Se realizó un ensayo de difusión en Agar para medir los halos de inhibición del gel experimental al 4,46 por ciento frente a P. gingivalis, la comparación con clorhexidina al 0,12 por ciento se evaluó con la prueba U de Mann-Whitney. Se adoptó un nivel de significancia del 5 por ciento .

Resultados:

Se identificaron 11 constituyentes en el aceite esencial, los principales componentes químicos fueron 3-heptadecene, (Z)- (36,13 por ciento ), 1-tridecene (14,7 por ciento ) y 1,8-cineole (9,72 por ciento ). La CMI del aceite esencial fue 36,195 mg/mL y la CMB fue 39,114 mg/mL. Los halos de inhibición del gel experimental de P. gingivalis fueron 25,533 mm ± 0,960. mm. Se observaron diferencias estadísticamente significativas frente a clorhexidina al 0,12 por ciento (23,282 ± 0,345) (p < 0,05).

Conclusiones:

El gel experimental al 4,46 por ciento compuesto por aceite esencial de Eucalyptus globulus Labill presentó una actividad antibacteriana importante frente a Porphyromonas gingivalis ATCC 33277(AU)
ABSTRACT

Introduction:

Medicinal plants have proved to have antibacterial properties for the control of periodontitis.

Objective:

Determine the antibacterial activity against Porphyromonas gingivalis ATCC 33277 of an experimental gel composed of essential Eucalyptus globulus Labill oil.

Methods:

An in vitro experimental study was conducted. The software EPi InfoTM was used to estimate the repetitions. The essential oil was obtained by steam entrainment, and its chemical composition was determined by gas chromatography / mass spectrometry. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were also evaluated. An agar diffusion test was performed to measure the inhibition haloes of the 4.46 percent experimental gel against P. gingivalis. Comparison with 0.12 percent chlorhexidine was evaluated with the Mann-Whitney U test. A 5 percent significance level was adopted.

Results:

A total 11 constituents were identified in the essential oil. The main chemical components were 3-Heptadecene, (Z)- (36.13 percent), 1-Tridecene (14.7 percentand 1,8-cineole (9.72 percent). MIC of the essential oil was 36.195 mg/ml, whereas MBC was 39.114 mg/ml. The inhibition haloes of the experimental P. gingivalis gel were 25.533 mm ± 0.960 mm. Statistically significant differences were observed versus 0.12 percent chlorhexidine (23.282 ± 0.345) (p < 0.05).

Conclusions:

The 4.46 percent experimental gel composed of Eucalyptus globulus Labill essential oil displayed considerable antibacterial activity against Porphyromonas gingivalis ATCC 33277(AU)
