  Purpose

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.
