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

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 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- and patient-level factors on annual costs was assessed using mixed modelling. RESULTS: A total of 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 6,998 (3,807) and 267 (148) Euro, respectively. Approximately 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.

Scaling and root planing vs. conservative surgery in the treatment of chronic periodontitis.

A renewed interest in conservative surgical techniques has been fueled by new technology, changes in referral patterns to periodontists and a desire to achieve periodontal health in the least invasive, most cost-efficient manner possible. Trends suggest that an increasing amount of periodontal care is being provided in the offices of general dentists. If true, it is likely that patients receiving care in these offices will be offered simpler surgical treatment modalities that do not require an extensive armamentarium. The purpose of this article was to review the effectiveness of six relatively simple surgical techniques - gingivectomy, flap debridement, modified Widman flap, excisional new attachment procedure, modified excisional new attachment procedure and laser-assisted new attachment procedure - and to compare the results obtained using these procedures with the well-known clinical benefits of scaling and root planing. The intent was to determine whether the benefits of surgical procedures in the hands of most general dentists extend beyond those of conventional nonsurgical therapy.

A randomized controlled trial on immediate surgery versus root planing in patients with advanced periodontal disease: a cost-effectiveness analysis.

AIM: To compare immediate surgery to scaling and root planing (SRP) in the treatment of advanced periodontal disease focusing on the prevalence of residual sites and cost-effectiveness (1); to evaluate the adjunctive effects of azithromycin in a second treatment phase (2). MATERIALS AND METHODS: Thirty-nine patients (18 males, 21 females; mean age: 54.6) received oral hygiene instructions and were randomly allocated to surgery (n = 19) or SRP (n = 20). Patients with residual pockets (≥6 mm) at 6 months received re-debridement of these sites and systemic azithromycin. Treatment groups were followed up to 12 months and evaluated in terms of clinical response parameters and cost-effectiveness. Chair-time was used to assess the financial impact of treatment. RESULTS: Both treatment arms were equally effective in terms of clinical outcome demonstrating less than 1% residual pockets at 12 months. Surgery imposed an extra 746 Euro on the patient up to 6 months when compared to SRP. At 12 months, 46 Euro of this amount could be offset as a result of a reduced need for supportive care. Only 6 patients in the surgery group needed systemic antibiotics, whereas 14 patients in the SRP needed such additional treatment. CONCLUSIONS: Although 700 Euro could be saved on average by performing SRP instead of surgery, the latter significantly reduced the need for supportive care and systemic antibiotics.
