Introduction: Dental biofilm is a complex structure formed from the adhesion of various microbial cells to the film acquired on the dental structure. These cells adhere to each other while synthesizing an extracellular matrix, becoming a highly organized community, which makes it difficult to remove and promotes resistance to antimicrobials. The presence of Staphylococcus aureus in the oral biofilm can cause an disturb in the microbiota, facilitating the beginning of a disease process. Aim: To evaluate the non-adherent ability of Eucalyptus globulus and Eucalyptus citriodora against Staphylococcus aureus strains. Results: It was possible to observe that the essential oil of Eucalyptus globulus inhibited the formation of the biofilm with a Minimum Adhesive Inhibitory Concentration (MAIC) similar to 0.12 % chlorhexidine digluconate, both of 1:8. The essential oil of Eucalyptus citriodora did not prevent bacterial adherence to the tube walls in any evaluated concentration. Conclusion: Only the essential oil of the species Eucalyptus globulus has nonadherent activity against Staphylococcus aureus and can be used as an alternative product to control the biofilm.

The oral cavity shows a reflex of the external flora, affected by the way of life of the individual, which shelters a different microorganism ecosystem for each anatomic region. Those microorganisms, majority commensals, have the ability of become pathogenic when in a state of imbalance, causing, among other diseases, a candida infection. In the oral cavity there are various Candida species, such as Candida albicans, which is the most common between the Candida variety and predominant among other fungus species. The objective of this project was to make a short literature review, searching for studies that approach the pseudomembranous candidiasis and its pathology in pre-school aged children. It was used the internet database to select the papers. Children in pre-school age possess a developing immune system and oral microbiota, what makes them susceptible to this kind of infection. Another conditions, such as bad oral hygiene, tooth decay, use of soother and Down Syndrome ease the imbalance of oral flora and, consequently, the candidiasis. The treatment must be individualized and based on diagnostic both with topical medication or associated with systemic medication. [ABSTRACT FROM AUTHOR]
