RAMIREZ, Paula et al. Prevalence of white spot lesions before and after orthodontic treatment. CES odontol. [online]. 2014, vol.27, n.2, pp.61-67. ISSN 0120-971X.

Abstract Introduction and objective: Orthodontic fixed appliances are a risk factor for dental caries, and thus the understanding its prevention, diagnosis and treatment should be an integral part of specialty training in orthodontics. The purpose of this study was to evaluate the prevalence of white spot lesions before and after orthodontic treatment in patients between 10 and 22 years of age using digital photographs. Materials and methods: Initial and final photographs of 87 patients and final casts of 59 patients were evaluated. Chart information included: Age, sex, clinical crown size, and presence of white spot lesions in all 12 anterior teeth; ICDAS criteria was used to determine the prevalence of white spot lesions (d2) and enamel micro cavity (d3). Results: 26.4% of patients developed white spot lesions during orthodontic treatment; there was no significant difference in the distribution by quadrants or gender; the prevalence of white spot lesions was higher in gingival third, upper right canine and teeth with greater clinical crown size. Conclusion: Prevalence of white spot lesions increased during the orthodontic treatment with a homogenous distribution by sex. Orthodontists must to be alert and develop preventive strategies in these patients
