Introduction: Few studies have described the presence of subgingival plaque of patients with chronic periodontitis and were unaware of the implications that may have its presence in the periodontal treatment. Objective: The purpose of this research was to assess the prevalence of yeasts in periodontal pockets, their influence on clinical parameters and their association with other periodontopathogens in chronic periodontitis. Materials and methods: We reviewed the clinical parameters (pocket depth, clinical attatchment level, bleeding on probing, plaque index, suppuration, mobility and furcation involvement) and the presence of yeast in 76 patients with chronic periodontitis (mean age, 46±8 years) in Medellin, Colombia. Subgingival samples were processed by culture. To determine the differences in clinical variables with the presence or absence of yeasts were used chi square and Mann-Whitney tests. Through a non-parametric correlation coefficient (Kendal's k) expressed the association with other periodontal pathogens (p <0.05). Results and conclusions: The prevalence of yeasts in periodontal pockets of patients with chronic periodontitis was 13.2%. There were eight subjects with C. albicans and two patients with non-specific species of Candida. There was a significant correlation between the presence of yeast and Prevotella melaninogenica (p <0.000). The role of yeasts in chronic periodontitis is not clear and further studies are needed to demonstrate the clinical significance of their presence.
