Aim: The aim of this study was to evaluate whether extraction thresholds in persons with severe periodontitis have changed between 2000 and 2010 and whether potential shifts have contributed to the reported decrease in tooth extractions in German adults over the last decades. Materials and methods: Data from two German population-based cohort studies in Northeast Germany (Studies of Health in Pomerania; SHIP-START [baseline 1997-2001; 11-year follow-up] and SHIP-TREND [baseline 2008-2012; 7-year follow-up] were used. In SHIP-START (SHIP-TREND) 522 (478) participants with severe periodontitis according to the CDC/AAP case definition were included. Patterns of maximum probing depth (PD) and maximum clinical attachment level (CAL) for retained and extracted teeth were compared between SHIP-START and SHIP-TREND participants. Results: No major differences in patterns of baseline maximum CAL of retained or extracted teeth were detected between SHIP-START and SHIP-TREND. Extraction thresholds were identified at the baseline maximum CAL ≥6 mm and ≥9 mm. Tooth-level incidence rates for extraction for baseline maximum CAL of 6 mm were comparable between SHIP-START and SHIP-TREND (17.1 versus 15.9 events per 1000 person-years). Conclusions: After a decade, teeth in persons with severe periodontitis were still extracted with minor or moderate attachment loss. A change of extraction pattern did not contribute to the higher tooth retention rate. This article is protected by copyright. All rights reserved.
