  • White spot lesions in orthodontics : comparison of the impact of fixed orthodontics appliances versus aligners
    Publication . Cretel, Mathilde; Pereira, François Durand
    Orthodontics is a specialty of dentistry that focuses on dental and facial aesthetics and harmony by correcting or improving dental, occlusal, and joint relationships. In comprehensive orthodontic treatment, there are two main types of appliances: conventional fixed appliances, which consist of brackets and wires, and removable appliances in the form of thermoformed plastic trays, known as aligners. The latter have emerged in recent decades, significantly transforming orthodontic treatment by offering a more aesthetic and removable alternative to fixed appliances. Patients often seek orthodontic treatment to improve or correct their dental or facial aesthetics. The treatment process, whether fixed or removable, can have side effects on oral health that should not be overlooked One of the most common concerns is the development of white spot lesions (WSLs), which are areas of enamel demineralization caused by prolonged plaque accumulation. Their whitish appearance results from an optical effect due to mineral loss in the surface and inner layers of the enamel, and they appear as well-defined white or brownish spots. WSLs are frequently observed during fixed orthodontic treatment, particularly around brackets, due to the increased difficulty in maintaining proper oral hygiene and the greater accumulation of bacterial plaque in these areas. They can also occur in orthodontic treatments with aligners, although oral hygiene is generally easier to maintain with this approach. This narrative review aims first to define white spot lesions and their etiology. It will then provide a brief overview of the two main types of orthodontic treatment, followed by a comparison of WSLs prevalence between them. Finally, prevention and treatment strategies for WSLs will be discussed.
