Oral health is essential for overall well-being, and the balance of the interdental microbiota plays a crucial role. Interdental spaces are unique ecological zones, particularly vulnerable to the accumulation of pathogenic biofilm due to lower natural defences. In adults, these areas promote periodontal diseases, which are associated with non-communicable diseases such as cardiovascular diseases, diabetes, and certain cancers. Interdental biofilms, especially in young adults, contain pathogens that can cause cavities and initiate periodontal diseases.
Preventing dysbiosis of the interdental microbiota from an early age is crucial for good oral and systemic health. However, conventional brushing techniques do not effectively reach these areas. The use of interdental brushes (IIB) is currently the most effective method to disorganise the biofilm, to reduce inflammation, and to restore a symbiotic microbiota. IIBs vary in shape, size, material, and cleaning effectiveness. A single study has demonstrated the daily effectiveness of calibrated IIBs in reducing dysbiosis and inflammation in young adults.
The main objective is to compare the reduction of interdental dysbiosis in healthy young adults who perform daily interdental hygiene using brushes with different technological and mechanical properties.
