The efficiency and benefit of using, the halogen light source used for bleaching of teeth, in bonding of orthodontic brackets (an in vivo study)

Abstract

Background: The property of the bleaching light sources is the wide and curved(the negative of the mouth curve) head of exposure. The aim of this study was to,test the efficiency of this devise to bond orthodontic brackets, via unique exposurefor the whole teeth, by comparing the rate of the brackets failure with thetraditional led light source used in orthodontic brackets bonding which utilizeslight exposure for every tooth separately, and evaluating the benefit of time savingthrough contrasting the time required for bonding with the ordinary led andhalogen light sources.Materials and methods: 856Roth 0.22 stainless steel brackets were bonded to 39patients by using one of the two light sources in the form of three groups;bleaching light group (13 patients / 225 brackets) , ordinary led light group (13patients /237 brackets), split mouth group( by using combination of the twosources, 13patients / 229 brackets).Results: There is no statistically significant difference between the light source usedfor bleaching and traditional led light source in bracket failure rates, and the timerequired for bonding by the bleaching light source is 22% and 5% of that requiredby ordinary led light and ordinary halogen light respectively.Conclusion: the light sources used for bleaching can be used effectively in bonding oforthodontic brackets with given advantage of saving time and effort.
