ARDILA MEDINA, Carlos Martin et al. Enterococcus faecalis in teeth with apical assintomatic periodontitis. AMC [online]. 2014, vol.18, n.4, pp.415-423. ISSN 1025-0255.

Background: asymptomatic apical periodontitis (AAP) covers a group of inflammatory diseases with complex pathogenesis including microorganisms associated with the host immune response. Objective: to determine if there is association between Enterococcus faecalis (Ef) and AAP and the oral condition of patients. Methods: a descriptive study was conducted from October 2010 to November 2011. The universe was composed of a total of 18 patients with endodontic infection and diagnosed with AAP without periodontal disease who requested for treatment at the Dental School of the University of Chile. Patients were selected according to the following inclusion criteria: patients between 18 and 70 years, with uniradicular teeth with primary endodontic infection and AAP, with enough tooth structure that would allow surgical isolation; teeth with gingival sulcus inferior to 3 mm and patients who did not report ingestion of antibiotics in the last three months. Patients with systemic chronic diseases and pregnant women were excluded. Results: nine patients presented Ef. On the other hand, the studied sample had a decay, missed, filled, surfaces index (DMFS) averaged 18, 17 COP ± 3, 59; in the case of positive Ef patients this rate was 18, 22 ± 4, 41 while for negative Ef was 18, 11 ± 2, 80 (p= 0.754) Conclusions: Enterococcus faecalis is a very prevalent microorganism in periodontal infections that is why strict aseptic measures are recommended during endodontic therapy.
