Brief Summary

Treatment directed towards the control of periodontal infections is to about 90% non-surgical procedures. There is evidence from a large number of randomized controlled studies that the efficacy in terms of clinical outcomes of a full-mouth ultrasonic debridement approach (FMUD) is comparable to that of traditional section-wise scaling and root planing (SRP). A hypothesis for the current effectiveness study is that comparable clinical effects will be obtained with the FMUD approach as with conventional section-wise SRP, but with significantly more favourable patient-centred and health-economic outcomes. This randomized study involves about 100 professionals (dental hygienists) and more than 850 patients at 40 dental clinics in the Vastra Gotaland Region, Sweden. The project not only evaluate treatment effects in terms of pertinent clinical outcomes, it also has a strong focus on patient-centered measures - patient-reported experience measures (PREM) and patient-reported outcome measures (PROM) - as well as health-economics.

Study Arms (2)

Full-mouth ultrasonic debridement

ACTIVE COMPARATOR

Motivation and instruction in proper oral hygiene. Before initiation of the subgingival debridement the patient must show sufficient self-performed infection control (full-mouth plaque score \<30%). One session of full-mouth ultrasonic pocket/root debridement using a piezoceramic ultrasonic instrument. A follow-up visit after 2-4 weeks is scheduled for oral hygiene control and re-motivation/re-instruction if indicated. At 3 and 6 months re-evaluation is performed and re-instrumentation of all sites showing a remaining probing pocket depth of ≥5 mm carried out. Final evaluation at 18 months.

Procedure: Full-mouth ultrasonic debridement

Section-wise scaling and root planing

ACTIVE COMPARATOR

Conventional treatment approach comprising motivation, oral hygiene instructions and section-wise scaling and root planing at required number of consecutive appointments with 1-2 week interval. Follow-up 2-4 weeks after the last session of SRP for oral hygiene control and re-instruction if indicated. At 3 and 6 months re-evaluation is performed and re-instrumentation of all sites showing a remaining pocket depth of ≥5 mm carried out. Final evaluation at 18 months.

Procedure: Section-wise scaling and root planing

Interventions

Motivation and instruction in proper oral hygiene. Before initiation of the subgingival debridement the patient must show sufficient self-performed infection control (full-mouth plaque score \<30%). One session of full-mouth ultrasonic pocket/root debridement using a piezoceramic ultrasonic instrument.
