JUP and periodontitis: Therefore, the main objectives of this work were twofold: to investigate the prognostic utility of oPMN count, as compared with BOP%, as a clinical marker for inflammation in the presence of periodontitis with advanced stages (i.e., 2 and 3) and grades (i.e., B and C) and to elucidate potential associations between oPMN count and BOP% with the presence of pathogenic microbial species Pg, Td, Tf, Aa, and Pi in a clinical setting.
