Moderate‐ to long‐term therapeutic outcomes of treated aggressive periodontitis patients without regular supportive care

Background and Objective Risk for deterioration in treated aggressive periodontitis (AgP) individuals remained unclear. This retrospective cohort study investigated 7‐26 years of periodontal outcomes and oral health‐related quality of life (OHRQoL) of young adults with advanced periodontitis. Material and Methods Eighty‐nine previously treated patients with AgP were re‐examined. Clinical and radiographic parameters before treatment discontinuation and at re‐examination were compared. OHRQoL at re‐call was assessed with the short‐form Oral Health Impact Profile (OHIP‐14S). Results None of the subjects adhered to suggested periodontal therapy and maintenance after discharge. Mean percentage of sites with probing pocket depth (PPD) ≥6 mm at re‐examination was 4.5 ± 5.9%. A total of 182 teeth had been lost over time. Tooth loss rate was 0.14/patient/year. From 68 subjects with documented favorable treatment outcomes, higher percentage of sites with PPD ≥6 mm at re‐examination and higher radiographic proximal bone loss was associated with current smoking status.
