The aim of this research is to evaluate the damage produced to the dental enamel after removing metallic braces and polishing the residual adhesive deposited on the teeth surface with three types of rotatory instruments. A total of 45 premolar were extracted, for orthodontic reasons, and divided randomly in three groups (n = 15): group A, Arkansas stone; group B, multi-laminated burs; group C, microdiamond burs were used. Each one of the samples was examined with the stereo microscope 0016813 in three phases: Before the cementing of the braces, after the braces removal, to define the amount of residual adhesive deposited on the enamel through the Adhesive Residual Index (ARI) to do this each image of the adhesive was digitalized and then vectorized using the Autodesk program “Autocad 2015”, and finally, the enamel after the final polish with each of the instruments was evaluated with the purpose of classifying them with the Enamel Surface Index (ESI). A comparative analysis was performed using: Lilliefors Analysis, which noted the use of non-parametric tests; Wilcoxon Sign to compare the initial and final state of each group; and Kruskal-Wallis to compare between groups and the adhesive residual index. Statistically significant differences demonstrated that multi-laminated burs caused less damage and maintained samples in an average Enamel Surface Index of 2.
