Abstract
OBJECTIVES: This study aimed to examine the relationships among self-reported oral health, oral hygiene practices, and oral human papillomavirus (HPV) infection in women at risk for sexually transmitted infections (STIs) in Ho Chi Minh City, Vietnam. STUDY DESIGN: Convenience and referral sampling methods were used in a clinic-based setting to recruit 126 women aged 18-45 years between August and October 2013. Behavioral factors were self-reported. Oral-rinse samples were tested for HPV DNA of 2 low-risk and 13 high-risk genotypes. RESULTS: A higher unadjusted prevalence of oral HPV infection was associated with poorer self-rated overall oral health (P = .001), reported oral lesions or problems in the past year (P = .001), and reported a tooth loss not because of injury (P = .001). Higher unadjusted prevalence of oral HPV infection was also associated with two measures of oral hygiene: lower frequencies of toothbrushing per day (P = .047) and gargling without toothbrushing (P = .037). After adjusting for other factors in multivariable logistic regression models, poorer self-rated overall oral health remained statistically associated with oral HPV infection (P = .042); yet the frequency of tooth-brushing per day did not (P = .704). CONCLUSION: Results corroborate the association between self-reported poor oral health and oral HPV infection. The effect of oral hygiene on oral HPV infection remains inconclusive.
