Pathogenic effects of P.gingivalis W83 on rat oral cavity. (A) The gingival tissues were inflammatory and bleeding after P.gingivalis W83 inoculation in rat oral cavity for 8 weeks. (B) Severe alveolar bone losses were found in rats with P.gingivalis W83 inoculation. Left: control groups. Right: rats inoculated with P.gingivalis W83 intraorally for 8 weeks
