INTRODUCTION

One of the great advances in the profession of orthodontics has been the introduction of light-cured adhesives.¹ Mills was the first to suggest the use of led in orthodontics.² bonding of orthodontic brackets started being employed in orthodontics in the 1960’s by using the enamel acid etching technique. At that time, only auto-polymerizing materials were available. With the introduction of light-activated adhesive systems, orthodontists had sufficient time to position the bracket on enamel surface and remove the excess material. This evolution has allowed the emergence of several other bonding methods using different composites and light-curing devices.

During the early 1980s, advances in the area of visible light curing took place, which ultimately led to the creation of a curing device that uses blue light.the next form of curing light developed was the quartz-halogen bulb; this device had longer wavelengths and allowed for larger penetration of the activity light for resin composites.³
