Description
Summary:Ng MC‐H, Ong MM‐A, Lim LP, Koh CG, Chan YH. Tooth loss in compliant and non‐compliant periodontally treated patients: 7 years after active periodontal therapy. J Clin Periodontol 2011; 38: 499–508. doi: 10.1111/j.1600‐051X.2011.01708.x 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
