ARDILA M, Carlos Martín  and  GUZMAN Z, Isabel Cristina. Unusual microorganisms in subgingival plaque of patients with chronic periodontitis. AMC [online]. 2012, vol.16, n.2, pp.153-161. ISSN 1025-0255.

Background: subgingival environment of patients with chronic periodontitis have been found unusual microorganisms including Gram-negative enteric bacilli and yeasts. Mechanical or antimicrobial therapy in these patients may be inefficient to treat or to control periodontal disease. The common feature unusual microorganisms share is to be opportunistic pathogens, taking advantage of immunosuppression conditions to cause or aggravate the disease. Objective: to present the prevalence of unusual microorganisms in subgingival plaque of patients with chronic periodontitis in a Colombian population. Method: 76 systemically healthy patients who were presented in the dental clinic at the Dental School of Antioquia University were evaluated. Subgingival samples were processed by cultivation.      Results: enteric Gram-negative bacilli in 20 patients and yeasts in 10 were observed. Conclusions: these findings have important therapeutic implications that must be taken into account for patients management with periodontal diseases.

Keywords : CHRONIC PERIODONTITIS; GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS; YEASTS; PERIODONTAL DISEASES.
