title: Bond failure of a no-mix adhesive during orthodontic treatment.
abstract: Bond failure of a no-mix adhesive was evaluated in 320 patients followed longitudinally during orthodontic treatment. Factors evaluated were the patient's gender, the complexity of the appliance, the bond site location, initial crowding, and caries development. The overall bond failure rate was 7.2%. Bond failures were significantly higher in the mandible, with the second premolars showing the highest prevalence (23%) (P <.001). There were significantly higher bond failure rates in boys than in girls (P <.05). There was a significant negative correlation between initial crowding and bond failure. Increased white spot lesions during treatment and complex appliance design were significantly correlated with high bond failure rates.
