IntroductionResearch on the association between periodontitis and oral human papilloma virus (HPV) infection is inconsistent. The cross-sectional association of severe periodontitis with oral HPV infection was investigated in a sample of Hispanic adults.MethodsData from the 2014–2016 San Juan Overweight Adults Longitudinal Study (n = 740) was analyzed. Periodontitis assessment and self-collection of oral HPV samples followed the National Health and Nutrition Examination Survey methodology. Periodontitis was defined using the Centers of Disease Control and Prevention/American Academy of Periodontology definition. HPV typing was performed using polymerase chain reaction. Multivariate logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs).Results5.7% of participants had oral HPV infection and 20.3% had severe periodontitis. Adults with severe periodontitis had higher odds of oral HPV infection than those with none/mild disease (OR=2.9, 95% CI: 1.0–8.4, p < 0.05) in multivariable analysis. Adults with clinical attachment loss≥ 7 mm and pocket depth PD≥ 6 mm had 2- to 3-fold higher odds of HPV infection.ConclusionsSevere periodontitis was positively associated to oral HPV infection. Longitudinal evaluation of periodontal inflammation's role in acquisition and persistence of oral HPV infection is needed, as periodontitis screening could identify individuals at increased risk of HPV-related oral malignancies.
Objectives Evaluate whether insulin resistance (IR) predicts the risk of oral inflammation, assessed as the number of sites with bleeding on probing (BOP) and number of teeth with probing pocket depths (PPD) ≥ 4 mm and BOP. Methods Data on 870 overweight/obese diabetes free adults, aged 40-65 years from the San Juan Overweight Adults Longitudinal Study over a three-year period, was analyzed. Baseline IR, assessed using the Homeostasis Model Assessment of IR (HOMA-IR) index, was divided into tertiles. BOP was assessed at buccal and lingual sites, and PPD at six sites per tooth. Negative binomial regression was used to estimate the risk ratios (RRs) for oral inflammation adjusted for baseline age, gender, smoking status, alcohol intake, education, physical activity, waist circumference, mean plaque index, and baseline number of sites with BOP, or number of teeth with PPD≥4 mm and BOP. The potential impact of tertiles of serum TNF-α and adiponectin on the IR-oral inflammation association was also assessed in a subsample of 597 participants. Results Participants in the highest HOMA-IR tertile at baseline, had significantly higher numbers of sites with BOP [RR=1.19, 95% confidence interval (CI): 1.03-1.36] and number of teeth with PPD≥4 mm and BOP (RR=1.39, 95% CI: 1.09 - 1.78) at follow-up, compared with individuals in the lower two HOMA-IR tertiles. Neither TNF-α nor adiponectin confounded the associations. Conclusion IR significantly predicts gingival/periodontal inflammation in this population.
Objectives: Oral human papilloma virus (HPV) infection is associated with nearly three-quarters of all oropharyngeal cancers in the United States. Research also suggests its association with periodontal disease. There are limited studies evaluating differences in HPV detection methods; however, oral rinse is considered the most sensitive detection method. We compared HPV detection by self-collected oral rinse versus self-collected cytobrush and assessed whether the strength of association between periodontitis and HPV is modified by the collection method.Materials and Methods: Data from a cross-sectional study of Hispanic adults in Puerto Rico (n = 346) who provided oral rinse and cytobrush samples for oral HPV detection and were clinically evaluated for periodontitis. The agreement between the oral mouthwash and cytobrush methods was assessed using the Kappa (κ) statistic. Logistic regression models were used to determine if the association between HPV infection and other risk factors varied by oral sample collection method.Results: HPV prevalence was slightly higher using cytobrush than oral rinse (5.8% vs. 4.3%). The sensitivity of cytobrush to detect oral HPV was 64.7%, and the specificity was 97.4%. We observed a κ of 0.61 (95% confidence interval [CI]: 0.45-0.78), indicative of fair to good agreement between the two collection methods. The association between oral HPV infection and periodontitis severity was stronger when using the oral rinse collection method (odds ratio [OR] = 3.23, 95% CI:1.06-9.84); the association was not statistically significant for cytobrush (OR = 1.96, 95% CI: 0.68-5.65).Conclusions: These findings support the significance of choosing the most suitable collection method in oral HPV-related studies. Selecting the most appropriate collection method is an essential criterion in oral HPV-related studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
