Research Abstract |
The detection frequency of P. gingivalis in NAFLD patients was significantly higher than that in the non-NAFLD control subjects(46.7% vs. 21.7%, odds ratio : 3.16). In addition, the detection frequency of P. gingivalis in NASH patients was markedly higher than that in the non-NAFLD subjects(52.0%, odds ratio : 3.91). Most of the P. gingivalis fimbria detected in the NAFLD patients was of invasive genotypes, especially type II(50.0%). Infection of type II P. gingivalis on NAFLD model of mice accelerated the NAFLD progression. The non-surgical periodontal treatments on NAFLD patients carried out for 3 months ameliorated the liver function parameters, such as the serum levels of AST and ALT.
