| Outline of Final Research Achievements |
According to previous findings, we presumed that periodontal disease may cause liver dysfunction through the increase of proinflammatory cytokine. Therefore, we conducted an epidemiological study to find a causal-relationship between periodontal disease and liver function. Our cross-sectional study of general men and women aged 30-79 years showed that lactoferrin levels in gingival crevice fluid was positively associated with serum levels of ALT, AST and ALP (p<0.05). We also conducted a clinical trial to examine a treatment effect of periodontal disease on liver function and found that the treatment have significantly improved serum levels of ALT and gamma-GTP among men (but not women) without drinking habit. Thus, our findings suggested a possible causal-relationship between periodontal disease and liver function.
