The prevalence of Eikenella corrodens in dental plaque and saliva samples of 282 volunteers was determined by a semiquantitative method with a selective medium. E. corrodens was recovered in 58.9% of plaque samples and 0.3% of saliva samples. This prevalence rate was not significantly altered (P greater than 0.05) by variables of sex, race, smoking habits, clinic attended by the patient, general health status, or age; however, patients 7 to 14 years old had a significantly higher prevalence rate (90.5%; P less than 0.05). E. corrodens should be considered as a potential pathogen in infections associated with and wounds inoculated by the human gingival flora.
