Costs for active periodontal therapy (APT, including scaling and root planing, open flap debridement, root resections, but not pocket elimination or regenerative surgery) and supportive periodontal therapy (SPT, including also costs for restorative, endodontic, prosthetic and surgical treatments) were estimated from a mixed payer perspective in Germany. The impact of tooth\u2010 and patient\u2010level factors on annual costs was assessed using mixed modelling.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 52 patients (mean [SD] age: 35.2\/6.8\u00a0years), with 26.5 (4.0) teeth (38% with bone loss &gt;50%) were treated. Mean follow\u2010up (retention) time was 16.9 (5.4) years. Total treatment costs per patient and per tooth were 6,998 (3,807) and 267 (148) Euro, respectively. Approximately 87% of the costs were generated during SPT, 13% during APT. Annual patient\u2010 and tooth\u2010level costs were 536 (209) and 20.1 (65.0) Euro, respectively. Annual tooth\u2010level costs were significantly increased in patients aged 34\u00a0years or older, male patients, former or current smokers, teeth with furcation involvement degree II\/III, and bone loss 50%\u201370%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Annual treatment costs for treating AgP patients were similar to those found for chronic periodontitis patients.
