Avaliação do potencial antiderente dos óleos essenciais de Pogostemon cablin e Gautheria procumbes contra Staphylococcus aureus.

Abstract

The control of biofilm associated with gingival and dental diseases, including caries, is a major challenge in dentistry, especially with regard to the possible triggering of systemic manifestations. Under this bias, microorganisms, such as Staphylococcus aureus, which cause pulmonary infection, can adhere to the biofilm of dental surfaces, prostheses, oral cavity mucosa and endotracheal tubes. When the bacterial plaque is not disorganized, this pathogen can be aspirated or enter the bloodstream through diseases in the periodontium, in order to initiate the infection of the lung parenchyma. This condition is one of the main causes of morbidity and mortality, which may be related to the multiple resistance of the most common strains of this bacterium to antibiotic therapy supporting mechanical action in hospital settings. Still, chlorhexidine is considered one of the most effective methods of combat, but its negative effects by chronic use end up also becoming a problem. Based on the above, alternative drugs are sought and phytotherapy is presented as an important tool with broad possibilities for research. Among the studies with natural products, a group that has been highlighted is that of essential oils, in view of their medicinal potential, such as antimicrobial, antifungal, antiviral, antitumor, spasmolytic, anticarcinogenic and non-adherent activity. In the group of plant species, the essential oils of Pogostemon cablin and Gaulteria procumbes have documented pharmacological properties. When investigating the non-stick potential of the aforementioned oils against a clinical strain of Staphylococcus aureus (Sa 101), relevant results were obtained. Gautheria procumbes oil stands out for having a high anti-adherent potential against the bacterial species under study, being superior to chlorhexidine digluconate, thus being an effective therapeutic option in intraoral antisepsis and surfaces of materials inserted in the oral cavity.
