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%, of which 8.2% have white spot lesions on the total number of teeth. 1% of damaged teeth form cavities. The upper and lower jaw teeth were damaged at a rate of 10.9% and 5.4%, respectively. Palace 1 has the highest rate of white spot lesions at 12.2%. TTDT accounted for 60.7% in the group of patients treated for 1-6 months and 63.6% in the group treated for 7-12 months. Conclusion: Patients undergoing orthodontic treatment have a high rate of white spot lesions, the upper jaw has more damaged teeth than the lower jaw, the anterior teeth group has the highest rate of damage, the common location is the gum side compared to the braces. Therefore, we must take appropriate preventive measures as well as predict the treatment process
