Distribution of white spots after de-bonding in orthodontic patients

Fixed orthodontic appliances can interfere with removing bacterial plaques from dental surfaces which can ultimately lead to white spot formation. The aim of this study was to evaluate the quantity of white spots lesions in orthodontic patients treated with fixed orthodontic appliances during different treatment periods and to reveal the teeth most commonly affected by white spot lesions. Materials and Methods: A total of 30 patients undergoing or scheduled for fixed orthodontic treatment were divided into two groups. The patient's sample was divided according to the duration of fixed orthodontic appliance treatment. In the first group treatment time ranged from 1 to 1.5 year, and in the second group from 1.5 to 2 years respectively. The patients were selected randomly during regular recall visits to the Orthodontic Clinic at the University Dental Clinic Center in Skopje. The patients were examined for the presence of white spot before insertion of the appliance and after its removal using visual examination. Results: This study showed that there was a significant increase in the formation of white spot lesions along with the increase in treatment duration. The first molars were the most affected teeth by white spots followed by canines and second premolars. Conclusion: The results of the study showed an increase of white spots formation with the increase of orthodontic treatment duration. The orthodontists should educate their patients to perform and maintain good oral hygiene by proper brushing techniques including all teeth not emphasizing anterior teeth only.
