Elevated Prevalence of Oral HPV Infection Among Females with Periodontitis: A Cross-Sectional Study.
Article in Oral health & preventive dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study investigated the association between periodontitis and oral HPV infection, while exploring the role of oral bacterial microbiota diversity. METHODS AND MATERIALS: Data from 4,685 adults in the NHANES 2009-2012 cycles were analysed. Periodontitis was defined based on clinical examination, and oral HPV infection was identified using PCR from oral rinse samples. Multivariable logistic regression models were employed to assess the relationship, adjusting for body mass index (BMI), age, sex, ethnicity, education, smoking, alcohol consumption, daily dental flossing, and history of systemic diseases. Subgroup analyses were stratified by age, sex, and education. Mediation analysis was performed to evaluate whether the oral microbiome acts as a mediator in the relationship between periodontitis and oral HPV infection.
resultsNo statistically significant overall association was found between periodontitis and oral HPV infection (P > 0.05). However, females with moderate to severe periodontitis exhibited increased odds of oral HPV infection (P 0.05). Oral HPV infection was associated with greater microbial diversity (higher operational taxonomic units [OTUs]). No significant mediating effect of the oral microbiome was observed.
conclusionModerate to severe periodontitis appears to be associated with higher odds of oral HPV infection in females. These findings highlight the potential relationship between oral health, microbial diversity, and oral HPV infection. CLINICAL IMPLICATION: In the general population, periodontitis does not appear to be a major risk factor for oral HPV; however, female with moderate to severe periodontitis and individuals with higher educati-on showed increased odds of oral HPV infection, suggesting that maintaining periodontal health may be particularly important for HPV related risk management in these subgroups.
