Background: The present investigation aims to estimate the frequency of Entamoeba gingivalis and Trichomonas tenax in periodontitis patients referring to Khorramabad Dental Faculty, Lorestan Province, Iran.

Methods: The present cross-sectional survey was carried out on 76 periodontitis patients (Based on the Periodontology Association protocols) referring to Khorramabad Dental Faculty during August 2017 to May 2018. The samples (saliva and dental plaque) after collection were smeared on a glass slide, and in next step using Giemsa stain were stained; finally by means of a light microscope were tested. A prepared questionnaire considering a number of data such as age, gender, use of toothbrush, etc. were provided by each patient.

Results: Among the 76 patients with periodontitis, these parasites were found in 24 (31.6%) patients including 13 (17.1%) patients for E. gingivalis, 11 (14.5%) patients for T. tenax. The obtained results indicates that although there was no significant relationship between age, gender, education, residence, smoking and the prevalence of E. gingivalis and T. tenax among the periodontitis patients; but a significant correlation was observed with mouthwash and teeth brushing (p<0.05).

Conclusion: The findings of current survey revealed that the remarkable prevalence of E. gingivalis and T. tenax in patients with periodontitis in Lorestan Province, Iran; indicating that E. gingivalis and T. tenax may possibly related to the progress of periodontitis. Nevertheless, consideration to oral health ideals, mainly brushing and use of mouthwashes may protect people from expose with these parasites.
