MATERIALS AND METHODS: This cross-sectional study was carried out on 20 subjects (7 male – 13 female) their age ranged between 12-34 years old. During fixed orthodontic treatment each tooth in four quadrants was examined by naked eye to detect the occurrence of WSLs from the 1 month to 6 month of treatment duration. RESULTS: The prevalence of WSL according to age, gender, and duration of the orthodontic treatment. The mean age of male were 19.43 (S.D= 6.37) and the mean age of female were 19.00 (S.D= 7.37) ; but statistically calculated non- significant (P-value >0.05). In the first visit the mostly affected teeth are upper right canine, upper left canine, and upper left lateral incisor, In second visit the most affected teeth are upper left canine, upper left lateral incisor, and lower right canine. In the third visit the mostly affected teeth are upper left canine, upper left lateral incisor, and lower right canine, In the fourth visit the most affected teeth are upper left canine and upper left lateral incisor.
