| Abstract | ||
| Background: The purpose of this in vivo study was to investigate the difference in brackets failure rate between light cured and chemical cured (no mix) composites used in brackets bonding procedures. Materials and methods :A total of 729 Roth 0.22 stainless steel brackets were bonded to 40 patients requiring orthodontic treatment in the form of 3 groups ;light cured 237 ,no mix 240 ,control(split mouth design)249. Results: The results showed non significant difference in brackets failure rate between the groups and the majority of the failed brackets were in the posterior region. Conclusion: Clinically, the light cured bonding system has a comparable strength to no mix | ||
