Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Methods: Oral examination was performed and blood IgG antibody titers against periodontal pathogens were measured by ELISA, in 1387 subjects. The cut-off value of IgG titer was determined in receiver operating characteristic curve analysis, and changes in periodontal clinical parameters and IgG titers by periodontal treatment were evaluated. The relationships between IgG titers and severity of periodontitis were analyzed.
