“…What can be seen in all these analyses is that the group that received periodontal treatment showed significant improvement in periodontal parameters, the PD reduced significantly ( Al-Katma et al, 2007 , Ortiz et al, 2009 , Pinho et al, 2009 , Erciyas et al, 2013 , Okada et al, 2013 , Khare et al, 2016 , Zhao et al, 2018 ), there was a significant gain in CAL ( Al-Katma et al, 2007 , Erciyas et al, 2013 , Okada et al, 2013 , Khare et al, 2016 ), and a significant decrease in BOP posttreatment ( Al-Katma et al, 2007 , Ortiz et al, 2009 , Erciyas et al, 2013 , Okada et al, 2013 , Khare et al, 2016 , Zhao et al, 2018 ). The reduction in PD and improvements in CALs can be attributed to the decreased size of inflammatory components after periodontal therapy, this decrease in inflammation in patients with chronic periodontitis according to Luthra et al, 2019 can be observed 30 days after non-surgical periodontal therapy.…”
