Abstract

oral parasitic infection. This study was designed to detect these parasites in oral cavity of patients with periodontitis
and gingivitis with some risk factors and compare it with healthy oral persons.
Material and Method: A total of 60 patients with periodontitis and gingivitis and 25 healthy person (control group)
enrolled in the present study. Two samples were collected from each patient, dental plaque and saliva samples.
These samples were stained with Giemsa stain and examined under light microscope, some factors were taken such
as PH saliva, age, sex, smoking habits, diabetes mellitus, blood pressure, heart disease and any history of antibiotic
consumption during the last six months.
Results: This result shown Entamoeba gingivalis and Trichomonas tenax in dental plaque samples was higher than in
saliva samples in patients with periodontitis (70%, 60%), (33%,20%) respectively. While in gingivitis it was shown that
these two parasites higher in saliva than the dental plaque (60%,46.6%),(46.6%,30.9%)respectively. these two parasites
are present in healthy individuals less than in patients with periodontitis and gingivitis . The presence of these
protozoans was related to the type of periodontal disease(p=0.0257),sex(p=0.043),age(p=0.0058),PH of
saliva(p=0.043) and risk factors (p=0.0168).
Conclusion: This study showed Entamoeba gingivalis more common in patients with periodontal disease whereas
Trichomonas tenax is that considered a protozoan in oral cavity. There was relationship between the presence of
these parasites and the type of periodontal disease and the risk factors.
