Inclusion criteria

Inclusion criteria: The number of cases enrolled in the present study was set at 32 subjects per group, including 16 female and 16 male patients. All participants were regularly visiting the outpatient clinics at the Danube Private University, Krems, Austria, and requested a professional tooth cleaning. The participants were young right-handed adults; their age ranged from 18 to 30 years (mean (±SD): 24.27 (± 2.90) years), with well to moderate oral hygiene (dental plaque detectable in less than 40% of all interdental spaces). The level of oral hygiene was determined by means of a commonly used oral hygiene index (API, approximal plaque index), combined with the determination of the oral tissue inflammation level via gingival index (PBI, papillary bleeding index). In addition to the signed informed consent mentioned above, further inclusion criteria were absence of systemic diseases and destructive periodontal disease (no bleeding on probing > 40%; no gingival pockets > 4 mm) as well as any known allergies to components of the Erythritol powder (AIR-FLOW Plus Powder; EMS) and/or the polishing paste (Cleanic; KerrHawe). Patients who underwent procedures of professional tooth cleaning have used any oral hygiene items or plaque dissolving mouth rinse solutions in the 24 hours prior to the in-tended treatment were not considered in the present investigation, due to a possible influence of the aforementioned measures on the dyeability of dental plaque.

Exclusion criteria

Exclusion criteria: Minor patients or patients over the age of 30. Patients with inadequate oral hygiene (API of 70-100%), poor physical and mental condition, severe systemic diseases, patients who are known to have allergies to components of the test products used in the study patients with fixed orthodontic appliances, patients with a destructive periodontal disease (BOP over 40%, gingival pockets over 4 mm), patients with recently performed PZR, left-handers, no declaration of consent. The subjects take part in another study.
