Apoptosis analysis of PMNs from controls (n = 16) and periodontitis subjects (n = 19) quantified by flow cytometry. The percentages of propidium iodide positive (PI+) PMNs were calculated, representing apoptotic cells. The different cell populations are expressed as a percentage of the total PMN cell population and are given as mean ± SD. *Comparisons periodontitis group versus control group, Student’s T-test, *P < 0.05. #Comparisons oPMN versus cPMN within subjects, Paired T-test, #P < 0.001
