Summary

Oral health is essential for overall well-being and systemic health. A key factor in preserving this health is maintaining the balance of the interdental microbiota, which involves regulating the quantity of pathogenic bacteria in interdental spaces (IS). These IS represent a unique ecological niche where the body has limited specific defense mechanisms, making them vulnerable to infections. In adults, the colonization of interdental spaces by pathogenic bacteria increases the risk of periodontal diseases, which are themselves associated with non-communicable diseases such as cardiovascular diseases, diabetes, and certain types of cancer. Preventing interdental microbiota dysbiosis from a young age is therefore a priority to maintain quality oral health and contribute to good systemic health throughout life. However, conventional brushing techniques cover only accessible tooth surfaces and cannot reach the interdental spaces. Currently, the use of interdental brushes (IDBs) is recognized as the most effective method for interdental hygiene. There are various types of IDBs, differing in several aspects that influence their effectiveness and usability. The main differences relate to their shape, size, and calibration using an interdental probe or not, allowing adaptation to different interdental space sizes. To date, only one study has demonstrated the effectiveness of daily calibrated interdental brush use in reducing dysbiosis and interdental inflammation among young adults. However, no research has yet been conducted to compare the effectiveness of the various types of IDBs available on the market (calibrated versus non-calibrated).
