Pilot study about utility of blood IgG antibody titer against periodontal pathogen for prediction of development of peri-implantitis - Pilot study about utility of examination for degree of periodontal infection in peri-implantitis

Results: Significantly more patients with BRIS were undergoing PSPT than PM. Significantly more patients with plasma IgG antibody titer to Porphyromonas gingivalis (P.g-IgG titer) not less than 1.68 were undergoing PSPT than PM. Also, significantly more patients with Tannerella forsythia in saliva were undergoing PSPT than PM. Significantly more patients with P.g-IgG titer not less than 1.68 and patients with T. forsythia in saliva were undergoing P with BRIS than P without BRIS. Conclusion: Periodontal bacteria-related examinations using blood and saliva may be useful as prognostic factors for periimplantitis.
