AB  - AIMS: To investigate the incidence and reasons for tooth loss during active 
      periodontal therapy (APT) and periodontal maintenance (PM) in a specialist 
      institution. MATERIAL AND METHODS: Retrospective data were collected from 273 
      patients [all compliers (AC)] and cross-sectional data from 39 patients after 
      discontinuation of PM [non-compliers (NC)] for at least 7 years after APT. 
      Descriptive statistics and regression analysis were performed. A comparison was 
      made between AC and NC. The prognostic factors associated with tooth loss during 
      PM were identified. RESULTS: AC lost 1.3 teeth/patient during APT and 0.9 
      teeth/patient during PM (mean 10.7 years). Tooth loss due to periodontitis was 
      0.03 teeth/patient/year. The age of 60 was a significant predictor of tooth loss 
      during PM (odds ratio of 2.1). NC lost 1.1 teeth/patient during APT and 2.7 
      teeth/patient during discontinuation (mean 9.6 years). Tooth loss due to 
      periodontitis was 0.22 teeth/patient/year, a sevenfold increase (p<0.05) compared 
      with AC. Regression analysis failed to identify any significant predictors for 
      tooth loss during the discontinuation of PM. CONCLUSIONS: In this study, the 
      provision of PM led to minimal tooth loss, especially due to periodontitis, for a 
      mean period of 10 years after APT. The completion of APT without PM may 
      predispose patients to lose more teeth compared with patients who undergo PM.
