The white spot lesions without cavitation caused by demineralization of enamel can be a common and undesirable problem of orthodontic treatment. Although the prevention of these injuries is one of the goals of the orthodontist, the rate of prevalence of white spot lesions (WSL) after orthodontics has been reported between 18.5% to 88% of cases, depending on the tooth in question. These lesions histologically resemble and feature similar to other white spot lesions without cavitation pathogenesis. Once formed, the aesthetic and dental health are compromised, however, the aesthetic factor is the biggest concern of the patient. Considering the existence of studies in vitro and in situ validated, embarked us the interest of conducting a randomized clinical trial aiming to evaluate methods of remineralization of white spot lesions (WSL) after orthodontic treatment, making use of three distinct protocols already used in vitro and in situ: 1. The education of hygiene; 2. Topical application of fluoride along with instruction in oral hygiene; 3. Use of fluoridated casein with hygiene instruction. This study parts from the null hypothesis that there is no differentiation between the three chosen protocols. 60 patients will be selected in the age group of 12 to 18 years in Piracicaba (SP), and the initial condition of the appearance of the enamel will be recorded by means of digital photographs using visual assessment. Patients in the study will be randomly divided into three groups of 20 patients each, to achieve the three protocols provided. The hygiene instruction will be held during the first clinical evaluation and every patient will receive a recorded CD containing the standard of hygiene for viewing instructions. Patients will be followed for a period of three months from the first clinical observation and photographic records. At the end of this period the clinical...
