Association of Periodontitis and Various Genotypes of Human Papillomavirus in Oral Rinse Specimens.

Objectives To evaluate the relationship between the presence of human papillomavirus (HPV) genotypes in oral rinse samples and periodontitis. Materials and methods This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) conducted in 2013-2014. The primary outcome was the periodontal status, categorized as either no periodontitis or mild periodontitis (combined) versus moderate to severe periodontitis (combined). The primary variable of interest was the presence of different HPV types in oral rinse specimens. Several confounders were selected based on previous evidence that demonstrated a potential association between HPV infectivity and periodontal disease. Results The final sample included 3103 participants. HPV genotypes 6, 35, 39, 55, 59, 71, 72, and 73 showed a statistically significant association with at least one of the periodontal statuses (p-value < 0.05). The presence of any HPV genotype was highly significantly associated with periodontal status, with a p-value of <0.001. Multivariable logistic regression analysis revealed statistically significant associations of HPV 6 and HPV 16 with periodontitis, adjusted for age, gender, diabetes, smoking, race, federal poverty level, last dental visit, and education level. Conclusion Our study highlights a potential link between periodontitis and specific HPV genotypes, such as HPV 6 and HPV 16, in oral rinse specimens. This suggests a complex interplay between periodontal disease and oral HPV infections, underscoring the need for further research to address public health concerns and inform preventive and treatment strategies. Clinical relevance Identifying a link between periodontitis and specific HPV genotypes, such as HPV 6 and HPV 16, in oral rinse samples could prompt early screening and tailored treatment approaches. This underscores the importance of oral health promotion and targeted interventions to address both conditions and improve overall patient outcomes.
