Enterococcus faecalis is a Gram-positive, facultative anaerobic coccus that can survive under harsh conditions. Studies have shown a positive relationship between biofilm formation and gelE gene expression in E. faecalis . The production of gelatinase (MMP 2) has been detected in 50% of E. faecalis isolates from endodontic and periodontal infections, which suggests its role in the pathogenesis of apical and marginal periodontitis. Although E. faecalis is not considered a periodontopathogen, this species has been more frequently detected in subgingival samples with periodontitis than from periodontally healthy subjects, suggesting that the local conditions in periodontitis may favor its colonization. Hence, the aim of the current study was to detect and compare the presence of E. faecalis in subgingival biofilms of healthy, gingivitis, and periodontitis subjects.
