简要总结
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.
详细描述
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
