Abstract

Background: We aimed to study the frequency and risk factors of oral cavity protozoa (Trichomonas tenax and Entamoeba gingivalis) in pregnant women in Lorestan province, western Iran. Methods: The current cross-sectional descriptive work was performed on 200 pregnant women referring to health centers of Lorestan Province, Iran during August 2021 to February 2022. Two specimens were obtained from each women by means of sterile swabs from saliva and dental plaques. The frequency of oral cavity protozoa was investigated using microscopic and conventional polymerase chain reaction (PCR). Results: E. gingivalis and T. tenax parasites were found in 41 (20.5%) and 46 (23%) of the pregnant women by microscopic and PCR test, respectively. Among positive samples, 29 (63.1%) of the pregnant women were infected with E. gingivalis; whereas 19 (36.9%) of the participants were positive for T. tenax. In the multivariate model, living in rural regions (p < 0.001) and brushing teeth (p = 0.021) were considerably linked with the prevalence of oral cavity parasites. Conclusion: The current study evidently exhibited the high frequency of oral cavity parasites (E. gingivalis and T. tenax) in pregnant women in Lorestan province, Western Iran. Awareness of the main risk factors for oral cavity parasites especially teeth brushing is necessary in refining public and oral health approaches in pregnant women. Thus, dental practitioners and gynecologists must be alert of these risk factors to carefully identify and manage oral health concerns in pregnant women to prevent the oral diseases and infections.
