Introduction: Enterococcus faecalis (E. faecalis) is a Gram-positive, facultative anaerobic, unsporulated coccus whose habitat is the gastrointestinal tract. It can also be found in the hepatobiliary tract, the vagina, and wounds on soft tissues. It has been shown that due to its high virulence, E. faecalis can penetrate the dentinal tubules, surviving chemical-mechanical instrumentation, colonize them at a depth of 300 µm and re-infest the canals even after being obturated, but the source of infection is not clear. The objective of this study was to determine the frequency and resistance profile of E. faecalis in the oral mucosa of patients attending dental consultation. Methods: samples were collected from the gingiva, gingival sulcus, palate, tongue, and cheeks of 200 adult subjects attending dental consultation. E. faecalis was identified by means of a screening that included catalase, hemolysis in agar blood, bile esculin, 6.5% NaCl, and PYR, confirming by a Microscan panel (DadeBehring). Results: E. faecalis was isolated from the oral microbiota of 10 samples (5%). Conclusions: this study found low frequencies of E. faecalis in the oral mucosa of subjects attending dental consultation.
