Introduction of light-cured adhesives has given a great contribution and has been the greatest advances in the field of orthodontics. The most popular orthodontic adhesive is the light-cure composite resin. These adhesives have provided the practitioner the luxury of unlimited curing time. They have reduced the risk of contamination, easier removal of excess peripheral adhesive, and increased working time to position the brackets accurately on the teeth. Compared with the halogen curing system, LED lights can achieve clinical bonding success with shorter curing time. Curing-light manufacturers claim that by increasing the light intensity, less curing time will be required to reach adequate bond strengths.
