Long-term treatment costs for aggressive periodontitis in a German population

Abstract

Aim

This study assessed the long-term annual costs for treating aggressive periodontitis (AgP) patients.

Methods

A cohort of compliant AgP patients was retrospectively evaluated. Costs for active periodontal therapy (APT, including scaling and root planning, 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- and patient-level factors on annual costs were assessed using mixed-modelling.

Results

52 patients (mean [SD] age: 35.2/6.8 years), with 26.5 (4.0) teeth (38% with bone loss>50%) were treated. Mean follow-up (retention) time was 16.9 (5.4) years. Total treatment costs per patient and per tooth were 6998 (3807) and 267 (148) Euro, respectively. 87% of the costs were generated during SPT, 13% during APT. Annual patient- and tooth-level costs were 536 (209) and 20.1 (65.0) Euro, respectively. Annual tooth-level costs were significantly increased in patients aged 34 years or older, male patients, former or current smokers, teeth with furcation involvement degree II/III, and bone loss 50-70%.

Conclusions

Annual treatment costs for treating AgP patients were similar to those found for chronic periodontitis patients. Certain parameters might predict costs.
