The anaerobic micro-environment of the grooved tongue surface provides optimal conditions for the survival of micro-organisms. These microbes may promote caries, periodontitis marginalis, periimplantitis as well as halitosis. A new device, the TS1 tongue vacuum cleaner, is designed to remove bacterial biofilm from the tongue’s surface. The aim of the present study was to both examine the acceptance of this tongue vacuum cleaner by children at the School Dental Clinic Basel as compared to a child’s manual tooth brush, and tongue cleaning at home for a 1-month period. This study did not investigate the cleaning effect. One hundred sixty-two children aged 5 to 18 years participated in this study. The acceptance of the tongue vacuum cleaner was significantly higher with 8.9 cm on the visual analogue scale (0 – 10 cm) in comparison to a child’s manual tooth brush with 7.8 cm (p < 0.001). After professional tongue cleaning, the children were asked to clean their tongues at home for a 1-month period, and to return a completed questionnaire (n = 66). The children estimated their acceptance of daily tongue cleaning with 8.3 cm on the VAS, their parents with 8.7 cm. Fifty-eight children reported willingness to continue cleaning their tongues at home after the 1-month examination time. The data show that the use of the tongue vacuum cleaner, as part of a professional oral prophylaxis, is well accepted by children and may help promote, along with professional instruction, home tongue cleaning on a regular basis.
