Background: It was shown that two parasites of Entamoeba gingivalis (E. gingivalis) and Trichomonas tenax (T. tenax) may be responsible for oral parasitic infection. This study was designed to evaluate the prevalence of these parasites in oral cavity of patients with periodontal disease and in healthy population in Shiraz, Southern Iran. Materials and Methods: A total of 50 patients with periodontal disease (case group) and 50 subjects with healthy gingiva (control group) entered in the present study. A questionnaire recorded general health, smoking habits, and any history of antibiotic consumption during the last six months for each patient. In the case group, saliva was collected by sterile swab and the gingival crevicular fluid by the paper point. The plaque and calculi were collected by sterile curette and scaler. In the control group, saliva and gingival crevicular fluid were collected and sent to laboratory for further studies. Results: In the case group, nine patients were infected, six with E. gingivalis and three with T. tenax. Seven patients had mobility of the teeth, one patient was smoker and five had previous history of antibiotic consumption. In the control group, only one subject was infected with E. gingivalis without any history of smoking and antibiotic consumption. Conclusion: Parasitic infections are relatively common in patients with periodontal disease. It seems that follow-up of instructions are essential in control of parasitic infection in Southern Iran.
