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

Abstract

Risk for deterioration in treated aggressive periodontitis (AgP) individuals remained unclear. This retrospective cohort study investigated 7-26years of periodontal outcomes and oral health-related quality of life (OHRQoL) of young adults with advanced periodontitis. 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). None of the subjects adhered to suggested periodontal therapy and maintenance after discharge. Mean percentage of sites with probing pocket depth (PPD) ≥6mm 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 ≥6mm at re-examination and higher radiographic proximal bone loss was associated with current smoking status. Patients with AgP with <20 teeth at re-call had worse OHRQoL than those with ≥20 teeth. Patients with higher full-mouth mean PPD also reported poorer OHRQoL. Treatment in patients with AgP who smoke and neglect proper supportive care, risk periodontal disease progression. Substantial tooth loss and higher full-mouth mean PPD led to poorer OHRQoL in this cohort.
