[Enamel demineralization in orthodontics. Systematic use of fluoride in prevention and treatment].

The development of the white spot demineralization associated with fixed appliance orthodontic treatment is a significant clinical problem. Several studies have reported a significant increase in the prevalence and severity of demineralization after orthodontic therapy. Orthodontists should be proactive and take active responsibility to prevent the development of WSL by educating their patients about the importance of maintaining an excellent dietary compliance and oral hygiene regime. In front of the appearance of the white spots, several preserving palliative treatments can be suggested.
