Abstract

OBJECTIVE: The purpose of this study was to evaluate the clinical performance of brackets cured with two light-curing units. MATERIALS AND METHODS: Forty female patients (between12-16 years old) who required fixed appliances were included in this study. Based on the characteristics of their lower arches, study participants were divided into two groups, A and B. In group A, the composites were cured on the right side by Ultralume LED2TM and on the left side by a conventional halogen unit. In group B, the sequence was reversed. A total of 160 brackets were bonded. After 12 months, bond failure rate was evaluated. RESULTS: We found that 18 brackets in the halogen group and 13 brackets in the LED group were debonded. No statistically significant differences were found in total bond failure rate and no enamel damage was clinically detected for either technique. CONCLUSION: These results suggest that LED dose curing does not result in more bond failure when compared with conventional halogen light curing.
