Relationship between hepatitis virus infection and dental status in an 80year-old population
Aim: Little is known about the relationship of hepatitis virus infection to dental status, especially in very elderly individuals. We evaluated hepatitis C, G, transfusion-transmitted (TT), and B virus infection in relation to dental status in 80-year-old subjects. Design and subjects: Of 1,282 individuals who were 80-years-old and resided in the Fukuoka Prefecture, Japan, 407 (156 male, 251 female) underwent oral examination and laboratory tests. Relationships between hepatitis virus infection, tooth number and community periodontal index (CPI) were analysed by logistic regression analysis. Results: The mean tooth number was 8.4. None of 404 individuals had HBs antigen (0%), while 26 of 406 were HCVseropositive (6.4%). Thirteen of the 405 (3.2%) and 161 of 406 (39.7%) had HGV RNA and TTV DNA, respectively. HCV infection was more prevalent in edentulous individuals (9.4% vs. 4.9%). Prevalence of HGV infection was significantly increased in edentulous individuals (6.5% vs. 1.5%). No significant differences were noted in prevalence of the TTV DNA between edentulous subjects and others. After adjustment for gender, smoking, and alcohol consumption, HGV RNA remained significantly more prevalent and HCV antibody still tended to be more prevalent, in edentulous subjects. TTV DNA tended to be more frequent in individuals with at least 20 teeth than in those with <19 teeth. No significant relationship was found between CPI and HCV, HGV, or TTV infection. Conclusion: Very elderly Japanese people showed an association of HGV infection with tooth loss, and weak associations of HCV infection with tooth loss and TTV infection with tooth retention. Key words: Hepatitis viruses, tooth loss, dental health, elderly population, periodontal disease
