prevalence of salivary gland disorders and lichenplanus in patients infected with chronic hepatitis C virus

ABSTRACT

This study was carried out to examine the oral health of Hepatitis C Virus infected patients. In particular, the prevalence of salivary glands disorders and Oral Lichen Planus. Eighty patients infected with HCV, who were not undergoing anti-viral treatment, were examined. The information collected from the patients included, demographic details together with perception of their oral health and access to dental care since they were diagnosed of hepatitis C. Both extra-oral and intra-oral examinations were conducted. Teeth present and visible caries were recorded, periodontal conditions were measured using a Community Periodontal Index of Treatment Need [CPITN] probe and denture fit and hygiene were assessed where appropriate. The soft tissues were examined and lichen planus was diagnosed clinically. The whole salivary flow rates were estimated using spitting technique. The oral health of this cohort was poor. Twelve patients had clinical evidence of oral lichen planus [OLP], though all were not confirmed histologically. The salivary flow rates were significantly lower [p < 0.001] than previously reported healthy controls. Of the 25 regular dental attenders, only 5 had encountered problems accessing dental care. Chronic HCV infected patients require significant oral health care and an effective oral health education is required for HCV-infected patients and their carers
