Oral health of patients, with hepatitis C virus infection: a pilot study

OBJECTIVES: This study examined the oral health of a cohort of hepatitis C virus (HCV) patients. In particular, the prevalence of lichen planus and xe rostomia were determined. Experiences of discrimination against HCV infecte d patients by their dentists were also recorded. METHODS: Forty patients in fected with HCV, who were not undergoing anti-viral treatment, were examine d. Patient information collected included demographic details together with patients' perception of their oral health and access to dental care since being diagnosed with hepatitis C. Both extra-oral and intra-oral examinatio ns were conducted. Teeth present and visible caries were recorded, periodon tal condition was measured using a Community Periodontal Index of Treatment Need (CPITN) probe and denture fit and hygiene were assessed where appropr iate. The soft tissues were examined and lichen planus diagnosed clinically . Salivary flow rates were estimated by the Salivette (R) system. RESULTS: The oral health of this cohort was poor. Eight patients had clinic al evidence of oral lichen planus (OLP), although this was not confirmed hi stologically. The salivary flow rates were significantly lower (P < 0.001) than in previously reported healthy controls. Of the 15 (37.5%) regular den tal attenders, two had encountered problems accessing dental care. CONCLUSIONS: Chronic hepatitis C patients have significant oral health need s. More effective oral health education is required for both HCV-infected p atients and their carers, including dental practitioners.
