Abstract

Introduction: There is a risk of damaging the enamel surface and changing its original morphology during orthodontic bonding and debonding procedure. Research on better adhesive removal methods which can effectively remove the residual resin and restore it best, to its original form are continuing till now. Studies have shown that Stain buster bur creates a smooth enamel surface close to natural enamel when compared to other polishing systems. Recently a new bur called Adhesive Residual Removal bur was introduced by Dentarum company to achieve a smooth enamel finish after debonding. In this study I have compared the enamel surface roughness after debonding and polishing with 4 different polishing burs.
Aim: The objective of this study is to compare and evaluate enamel surface roughness after debonding and evaluated using four different finishing and polishing systems.
Materials and Methods: After debonding adhesive resin is removed from the buccal surface of 80 premolars. Based on the Bur used for polishing the tooth surface it is divided into four groups of 20 each. Group 1-Tungestine carbide system, Group 2-Enhance finishing and polishing system, Group 3-fiber reinforced stainbuster bur, and Group 4- adhesive residual remover bur. Quantitatively measurement was done with the help of surface roughness tester and qualitative measurement was done using scanning electron Microscope (SEM).
Results: Highest post-polishing roughness was observed in tungsten carbide bur (1.37 ?m) followed by enhance pogo bur (1.05 ?m), adhesive residual remover bur system (0.83 ?m), and Stainbuster bur (0.72 ?m) (p value < 0> Conclusion: The smoothest enamel surface was produced by Stainbuster bur that was close to the natural enamel followed by Adhesive residual remover bur, Enhance system, and tungsten carbide bur.
