Full-mouth ultrasonic debridement
Section-wise scaling and root planing
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.
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.
