JUP and Periodontal Pocket: We determined that oPMN level exhibits a higher Sp for increased prevalence of Pg and Pi; hence, these results may suggest that an oPMN level >1.47 × 106/mL could be potentially useful to identify periodontal pockets with high concentrations of Pg and Pi (e.g., promoting targeted antimicrobial therapy in recurrent periodontal pockets); however, in comparison to BOP% the differences observed were not statistically significant.
