Introduction: a global understanding of the bacterial composition of periodontal infection is necessary to allow the establishment of specific preventive and therapeutic strategies. Objective: to investigate the composition of the subgingival microflora of patients with chronic periodontitis in a Colombian population. Materials and methods: parameters were examined and the presence of subgingival microorganisms in 76 patients with chronic periodontitis in Medellin, Colombia. Subgingival samples were processed by culture. We used chi square test and Mann-Whitney test to determine differences between the clinical variables with sociodemographic (p <0.05). Results and conclusions: We found a higher insertion loss in men and higher rates of plaque, suppuration, mobility, and furcation commitment compared with women. The most prevalent microorganisms were P. gingivalis (64.4%), F. nucleatum (46.3%) and P. intermediate/nigrescens (44.3%). We found Gram-negative enteric rods in 20 (26.31%) of 76 patients. The prevalence of yeasts in periodontal pockets of patients with chronic periodontitis was 13.2% (10/76). These findings have important therapeutic implications that must be considered for the management of periodontal patients in Colombia.

Keywords : Chronic periodontitis; subgingival plaque; periodontopathogens; enteric; yeast.
