Distribution of the adhesive remnant index (ARI) scores for the three different adhesives used in this study (Transbond XT = blue, iBond = grey, and Scotchbond = green; n = 270). An ARI of 0 corresponds to 0% adhesive on the tooth and 100% adhesive on the bracket. An ARI of 1 corresponds to less than 50% of the adhesive on the tooth and more than 50% of it on the bracket. An ARI of 2 corresponds to more than 50% of the adhesive on the tooth and less than 50% of it on the bracket, and an ARI of 3 corresponds to 100% of the adhesive on the tooth and 0% on the bracket. An ARI of 4 corresponds to surface fractures.
