Abstract

Objective: Demineralization of tooth enamel or white spot lesions is one of the most common risks in orthodontic patients, especially in the group of patients with poor oral hygiene using fixed orthodontic appliances. Determining the rate of white spot lesions around braces on permanent teeth in orthodontic patients will help doctors in prognosis, prevention as well as treatment for patients. Research methods: 90 patients, undergoing orthodontic treatment at National Hospital of Odonto-Stomatology, Hanoi with fixed appliances for 1 month or more on permanent teeth, were evaluated for the rate, location, and extent of white spot lesions after 1 month of treatment. Result: The rate of white spot lesions is 55.6%. The upper and lower jaw were damaged at a rate of 10.9% and 5.4%, respectively. The upper right jaw has the highest rate of white spot lesions at 12.2%. The tooth most affected by white spot lesions is lateral incisor maxillary with a rate of 17.2%. Conclusion: Patients undergoing orthodontic treatment have a higher incidence of white spot lesions, with the upper arch showing more affected teeth than the lower arch. The anterior teeth group has the highest rate of lesions.
