Brief Summary

Because of the difficulties of disorganizing the dental biofilm in these adolescents with fixed orthodontic treatment, electric toothbrushes have been proposed as an alternative to manual toothbrushes. Electric toothbrushes, available in a wide range of price points, have been developed with the goal of replicating the complex motions required by the manual toothbrush and making plaque removal more efficient. However, the overall effect size is limited, and the clinical relevance is not yet clear. Applied to orthodontics, specialized manual toothbrushes have also recently been developed. Few recent clinical trials have been conducted in patients with orthodontic appliances. Thus, the question of whether and which type of manual or electric toothbrushes may be beneficial for patients with orthodontic appliances is still unresolved. Given the variety of toothbrushes available on the market, there is a need for sound clinical research to evaluate their effectiveness to guide professional recommendations. This work will provide a significant advance in the knowledge of the potential of the latest generation of electric toothbrushes on gingival inflammation, potentially reducing the risk of caries and gingival lesions.
