Fluoride Varnish, Ozone, Octenidin and WSLs in Orthodontic Patients

In patients from the study groups I, II, III, IV a professional mechanical tooth cleaning (PMTC) including air-polishing was proceeded on every visit using a glycine-based prophylaxis powder (Air-Flow Soft, EMS, Switzerland).

In patients from groups I, II, III, IV a fluoride varnish of 5% NaF (Profluorid Varnish, Voco, Germany) was applied with a microbrush. Every patient was instructed to stop from drinking and eating for the next two hours (as recommended by the manufacturer).

Patients from groups II and IV were additionally subjected to in-office ozone therapy using OzonyTron-OZ (Mymed, Germany). Ozone was applied on a silicone double-jaw tray of a proper size (allowing even ozone distribution in the oral cavity) following professional mechanical tooth cleaning. A Full Mouth Desinfection program lasting 5 minutes was used.

Patients from groups III and IV received a domestic mouthrinse (Octenidol MD, Schülke, Germany) and were recommended to use 15 ml of the liquid for 30 seconds after evening toothbrushing.
