title: Carious lesions in patients undergoing orthodontic treatment.
abstract: OBJECTIVE
  To record the newly developing carious lesions in patients receiving fixed orthodontic treatment.
  
  
  METHODS
  A descriptive cross sectional study was conducted from January to June 2010. Group A (6 months of treatment) comprised of 45 patients, compared to Group B (12 months of treatment) 45 patients. In both groups no cavitation was present; all carious lesions were filled at the start of orthodontic treatment.
  
  
  RESULTS
  The frequency of caries increased with the time period rise after orthodontic treatment. Patients after 12 month treatment had more carious lesions than at 6 month; caries activity increases in orthodontic patients.
  
  
  CONCLUSIONS
  Patient motivation to maintain their oral hygiene with the use of fluoride mouthwashes reduces the amount of carious lesions.
