Clinical comparison of three kinds of orthodontic adhesives

30 patients with fix orthodontic treatment were randomly divided into 3 groups( n =10). Westlake enamel adhesive resin,3M light-curing adhesive and chemical-curing adhesive were used in group A,B and C respectively for bracket bonding in orthodontic treatment. The exfoliation rate and the performance price ratio of the brackets were compared 1,3,6 months after treatment. All of these three kinds of the orthodontic adhesives achieved satisfactory results,while the non-mixing type of the Westlake enamel adhesive resin showed relatively higher ratio of performance to price.
