Introduction: The relationship between the oral microbiota and serious infections in patients kept in intensive care units (ICU) has been established, mainly for patients with dentures or partials, since oral biofilm can become reservoir of micro-organisms that are not part of this microbiota. Objective: This study aimed to evaluate the presence of the main periodontal pathogens and infections in the mouth of patients kept in intensive care units. Material and method: Data were obtained on the health conditions of 156 patients held for more than 72 hours in the ICU environment. Intraoral clinical examination was carried out and collection of samples of saliva and oral mucosa, respiratory secretions, blood and urine. The presence of the main oral and opportunistic micro-organisms associated with hospital-acquired infections were evaluated by means of the polymerase chain reaction (PCR). Statistical analysis was performed by Mann-Whitney tests and Test T, while the correlation between the variables was obtained by Spearman test, all at a significance level of 5%. Results: There was a negative correlation between the presence of leukocytes and some oral opportunistic pathogens and exogenous. The microorganisms studied were more prevalent in male gender and obligate anaerobes and capnofilicos microorganisms from oral cavity were more relevant in systemic infections than the exogenous opportunistic pathogens, such as Enterobacteriaceae and Pseudomonas. Conclusion: It was concluded that the fragility of the oral health of patients admitted to ICU, sometimes with immune suppression associated with the colonization and/or infection from opportunistic micro-organisms can be an aggravating factor in the deterioration and worsening of the patient's systemic framework
