Entamoeba gingivalis and Trichomonas tenax are protozoa that are usually found in the oral cavity of humans. E. gingivalis lives on the surface of the teeth and gums, gum pockets near the base of the teeth, and rarely in the crypts of the tonsils. They are usually spread by direct person-to-person contact through kissing, dousing, or sharing eating utensils. It is known that up to 95% of people with poor oral hygiene may be infected with this amoeba. On the other hand, Trichomonas tenax is a small trichomona that is usually found in the oral cavity of 5-10% of humans. Although they are considered non-pathogenic anaerobic commensals, the harborage of this protozoan is more common among people with poor oral hygiene or disease. Epidemiological reports have shown variable prevalence rates of E. gingivalis infection among children, and its occurrence may vary according to age, presence of gingivitis, periodontitis, and immunosuppressive conditions. School-age children and adolescents are extremely susceptible to a wide range of gingival infections including bacteria and protozoa. The objective of this work is to determine the prevalence of the protozoa E. gingivalis and T. tenax in adolescents between the ages of 10 and 19 in a population of 185 patients from the Peruvian city of Huancayo, Peru. The prevalence was higher in the female population (14.05%) than in the male population (11.35%), with a higher percentage of prevalence between the ages of 17 to 19 years (12.43%), lower salivary pH to 6.7 and with periodontal diseases (16.22%). The statistical results showed that age (p=0.001), salivary pH (p=0.024) and diagnosis of other periodontal pathologies (p<0.001) were statistically significant.
