Evaluation of Enamel Surface Roughness after Various Finishing Techniques for Debonding of Orthodontic Brackets.

Objective: The aim of this study was to evaluate the surface roughness of enamel after debonding with various types of burs.

Methods: The buccal surfaces of 20 mandibular incisors for each group of bur were subjected to profilometer analysis, and three parameters of surface irregularity were recorded. After bracket debonding, adhesive remnants were removed by tungsten carbide burs in low-speed, high-speed, and stainbuster settings.
