Mechanical Periodontal Therapy Recovered the Phagocytic Function of Monocytes in Periodontitis

Percentage of NBT reduction, nonstimulated (a) or stimulated (b), by cells obtained from control individuals (C) or with periodontitis before (PB) or after (PA) mechanical treatment for plaque removal. The results showed that the treatment increased the percentage of nonstimulated and stimulated NBT reduction compared with the control group (PA > C) (Mann–Whitney, ) or with the cells obtained before treatment (PA > PB) (Wilcoxon, ). There were no differences in the percentage of NBT reduction by control group cells and those obtained from periodontitis before treatment (PB) (Mann–Whitney, ).
