title: Clinical survey of Entamoeba gingivalis by multiple sampling in patients with advanced periodontal disease.
abstract: A clinical survey of Entamoeba gingivalis was conducted in patients with advanced periodontal disease. A total of 100 specimens were taken from 10 patients (four females and six males) who were each sampled at 10 disto-facial random sites. The oral hygiene of the persons scored from good to fair to poor and very poor. The age of the test persons ranged from 20 to 68 years. All persons examined harbored E. gingivalis: the minimum prevalence was four sites positive out of 10 and the maximum prevalence was 10 sites positive out of 10 for the protozoan. It is recommended that for reliable testing of the presence of E. gingivalis at least five-10 different sites should be examined within the periodontium of each patient. Data reported earlier in the literature on the incidence of E. gingivalis--obtained after a single sampling per individual--are believed to be on average too low and, therefore, should be interpreted with caution.
