- Abstract
Aim This retrospective longitudinal study assessed the risk of and prognostic factors for tooth loss in patients with generalized aggressive periodontitis ( GAgP) after periodontal treatment in a university setting. Methods Fifty-seven patients (1,505 teeth) were examined before (T0) and after active periodontal therapy ( APT, T1) as well as after 17.4 ± 4.8 [range: 9-28] years of supportive periodontal therapy ( SPT, T2). Descriptive statistics and a Cox-proportional-hazards shared-frailty model were applied. Results Overall, 98 and 134 teeth were lost during APT and SPT, respectively, with 0.14 ± 0.18 teeth being lost per patient and year. During SPT, three patients (5%) lost ≥10 teeth, 14 (25%) lost 4-9 teeth, 40 lost 0-3 (70%) teeth, respectively. One-third ( n = 19) of all patients lost no teeth. Mean PPD of the teeth surviving SPT was stable from T1 (3.5 ± 1.1 mm) to T2 (3.4 ± 1.1 mm). Nearly, 84% of all survived teeth showed stable or improved bone level at T2. Risk of tooth loss was significantly increased in active smokers ( HR[95% CI]: 4.94[1.91/12.75]), the upper dental arch (1.94[1,16/3.25]), with each mm of residual PPD (1.41[1.29/1.53]), teeth with furcation involvement (FI) ( HR 4.00-4.44 for different degrees) and mobility (5.39 [2.06/14.1] for degree III). Conclusion Within the provided conservative treatment regimen, GAgP patients lost only few teeth.
