Methods In this retrospective cohort study, 135 patients were examined after active periodontal therapy (APT) and periodontal maintenance for 5.09-8.65 years (mean 6.16±0.74 years). Regression models were applied to identify risk factors associated with tooth loss and disease progression. Results Stage IV periodontitis (Incidence Rate Ratio (IRR)=4.61; 95%CI [2.97,7.18], p<0.001), the presence of ≥5 sites with probing pocket depth (PPD)≥5mm at the end of APT (IRR=2.04; 95%CI [1.32,3.20], p<0.01), and residual PPD≥7mm at the end of APT (OR=3.01; 95%CI [1.14, 7.94], p<0.05) were risk factors for tooth loss. Residual PPD of 5mm (OR=2.02; 95%CI [1.20, 3.40], p<0.01) and 6mm (OR=2.41; 95%CI [1.22, 4.76], p<0.05) at the end of APT were risk factors for disease progression. Above 3mm, each 1mm increase in maximum PPD/clinical attachment loss was associated with an increased risk of tooth loss and disease progression. Conclusions Stage IV periodontitis is associated with an increased risk of tooth loss. Teeth with PPD≥5mm at the end of APT are at risk of periodontitis progression or tooth loss.
