The study investigates the effect of supra- and subgingival rinsing of 10% PVP prior to ultrasonic debridement in patients with periodontitis (as compared to rinsing with water) in terms of post treatment bacteraemia. Study design: Randomized split-mouth (cross-over) study on 20 generally healthy subjects.
Process: Test treatment: * 1 min mouthwash with 10% PVP-iodine * 1 min subgingival rinsing with 10% PVP-iodine * 1 min ultrasonic debridement with 10% PVP-iodine as cooling liquid * blood sampling from the V.mediana cupidi Control: * 1 min mouthwash with water * 1 min subgingival rinsing with water * 1 min ultrasonic debridement with water as cooling liquid * blood sampling from the V.mediana cupidi lysis, culturing and analysis of bacteria in the samples
