J Clin Periodontol 2010; 37: 346–352. doi: 10.1111/j.1600-051X.2010.01541.x. Abstract Background: To date, no studies have evaluated the effect of patient age on the treatment response following non-surgical periodontal therapy (NSPT). Aim: To evaluate the outcomes of NSPT in two cohorts of patients with a substantial age difference. Materials and Methods: Two groups of periodontitis patients with a substantial age difference (younger group, Y, and older group, O) were retrospectively selected. The effectiveness of NSPT was assessed by evaluating the changes in the prevalence of sites with different pocket probing depths (PPD) as well as the changes in patient- and site-specific bleeding on probing (BoP) scores. Results: Y group comprised 57 patients, mean age: 34.7 ± 4.4 years, and O group comprised 60 patients, mean age: 58.9 ± 5.3 years (p
